Question

斐伊川，还有很多人已经发布了很多关于这个的问题。但是这里的情况有所不同。

我需要提取前三位数字即。版本号$(major).$(Minor).$(Build)。我该怎么做？??我试过AssemblyInfo任务...但该任务只是为了覆盖版本号。不提取版本号。

我需要提取前三个数字并将它们分配给某个属性。以供进一步使用。

好吧，我可以使用FileUpdate task.like ::

覆盖它们

<FileUpdate 
    Files="@(AssemblyFile)" 
    Regex='(\d+)\.(\d+)\.(\d+)\.(\d+)' 
    ReplacementText='$1.$2.$3.$(Revision)'>
</FileUpdate>

现在我如何使用他们的价值即。 $1,$2,$3分配给属性。???

感谢名单。

Answer 1

您可以从文件中读取行，使用正则表达式获取字符串并根据需要进行更改。如果您使用的是MSBuild 4.0，则可以使用属性函数，这样您就可以访问.NET API。这个例子应该给你前三个AssemblyVersion号码。

<Target Name="ReadAssemblyVersion">

    <ReadLinesFromFile File="$(VersionFile)">
        <Output TaskParameter="Lines"
                ItemName="ItemsFromFile"/>
    </ReadLinesFromFile>

    <PropertyGroup>
        <Pattern>\[assembly: AssemblyVersion\(.(\d+)\.(\d+)\.(\d+)</Pattern>
        <In>@(ItemsFromFile)</In>
        <Out>$([System.Text.RegularExpressions.Regex]::Match($(In), $(Pattern)))</Out>
    </PropertyGroup>

    <Message Text="Output : $(Out.Remove(0, 28))"/>

</Target>

令人敬畏的线程，基于Alex和RobPol的工作，我能够定义受semver.org（Major，Minor，Patch，PreRelease）启发的扩展的msbuild属性。我选择解析AssemblyInformalVersion，因为这是与SemVer兼容的唯一属性。这是我的例子：

<PropertyGroup>
    <In>$([System.IO.File]::ReadAllText('$(MSBuildProjectDirectory)\Properties\AssemblyInfo.cs'))</In>
    <Pattern>\[assembly: AssemblyInformationalVersion\("(?&lt;Major&gt;\d+)\.(?&lt;Minor&gt;\d+)\.(?&lt;Patch&gt;[\d]+)(?&lt;PreReleaseInfo&gt;[0-9A-Za-z-.]+)?</Pattern>
    <AssemblyVersionMajor>$([System.Text.RegularExpressions.Regex]::Match($(In), $(Pattern), System.Text.RegularExpressions.RegexOptions.Multiline).Groups["Major"].Value)</AssemblyVersionMajor>
    <AssemblyVersionMinor>$([System.Text.RegularExpressions.Regex]::Match($(In), $(Pattern), System.Text.RegularExpressions.RegexOptions.Multiline).Groups["Minor"].Value)</AssemblyVersionMinor>
    <AssemblyVersionPatch>$([System.Text.RegularExpressions.Regex]::Match($(In), $(Pattern), System.Text.RegularExpressions.RegexOptions.Multiline).Groups["Patch"].Value)</AssemblyVersionPatch>
    <AssemblyVersionPreRelease>$([System.Text.RegularExpressions.Regex]::Match($(In), $(Pattern), System.Text.RegularExpressions.RegexOptions.Multiline).Groups["PreReleaseInfo"].Value)</AssemblyVersionPreRelease>
</PropertyGroup>

您可以通过在.csproj中添加以下内容来测试此操作的输出：

  <Target Name="AfterBuild">
    <Message Text="$(AssemblyVersionMajor)"></Message>
    <Message Text="$(AssemblyVersionMinor)"></Message>
    <Message Text="$(AssemblyVersionPatch)"></Message>
    <Message Text="$(AssemblyVersionPreRelease)"></Message>
</Target>

Ex：来自我的AssemblyInfo.cs的片段：

[assembly: AssemblyInformationalVersion("0.9.1-beta")]

将输出：Major：'0'，Minor：'9'，Patch：'1'，PreRelease：' - beta'

Answer 3

基于Alex的回答，我使用RegEx来读取AssemblyVersion（以及其他信息），并在我的WiX / MSI文件名和版本字符串中使用它。希望我的回答不是太吵。

这是我的.wixproj文件的顶部。兴趣点是第一个 PropertyGroup ， OutputName 和 DefineConstants ：

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <PropertyGroup>
        <In>$([System.IO.File]::ReadAllText('$(MSBuildProjectDirectory)\..\MyApplication\Properties\AssemblyInfoCommon.cs'))</In>
        <Pattern>^\s*\[assembly: AssemblyVersion\(\D*(\d+)\.(\d+)\.(\d+)</Pattern>
        <AssemblyVersionMajor>$([System.Text.RegularExpressions.Regex]::Match($(In), $(Pattern), System.Text.RegularExpressions.RegexOptions.Multiline).Groups[1].Value)</AssemblyVersionMajor>
        <AssemblyVersionMinor>$([System.Text.RegularExpressions.Regex]::Match($(In), $(Pattern), System.Text.RegularExpressions.RegexOptions.Multiline).Groups[2].Value)</AssemblyVersionMinor>
        <AssemblyVersionBuild>$([System.Text.RegularExpressions.Regex]::Match($(In), $(Pattern), System.Text.RegularExpressions.RegexOptions.Multiline).Groups[3].Value)</AssemblyVersionBuild>
        <Pattern>^\s*\[assembly: AssemblyDescription\(\s*"([^"]+)"</Pattern>
        <AssemblyDescription>$([System.Text.RegularExpressions.Regex]::Match($(In), $(Pattern), System.Text.RegularExpressions.RegexOptions.Multiline).Groups[1].Value)</AssemblyDescription>

        <Pattern>^\s*\[assembly: AssemblyCompany\(\s*"([^"]+)"</Pattern>
        <AssemblyCompany>$([System.Text.RegularExpressions.Regex]::Match($(In), $(Pattern), System.Text.RegularExpressions.RegexOptions.Multiline).Groups[1].Value)</AssemblyCompany>
    </PropertyGroup>
    <PropertyGroup>
        <Configuration Condition=" '$(Configuration)' == '' ">Debug</Configuration>
        <Platform Condition=" '$(Platform)' == '' ">x86</Platform>
        <ProductVersion>3.7</ProductVersion>
        <ProjectGuid>MYGUID00-840B-4055-8251-F2B83BC5DBB9</ProjectGuid>
        <SchemaVersion>2.0</SchemaVersion>
        <OutputName>$(AssemblyProduct)-$(AssemblyVersionMajor).$(AssemblyVersionMinor).$(AssemblyVersionBuild)</OutputName>
        <OutputType>Package</OutputType>
        <WixTargetsPath Condition=" '$(WixTargetsPath)' == '' AND '$(MSBuildExtensionsPath32)' != '' ">$(MSBuildExtensionsPath32)\Microsoft\WiX\v3.x\Wix.targets</WixTargetsPath>
        <WixTargetsPath Condition=" '$(WixTargetsPath)' == '' ">$(MSBuildExtensionsPath)\Microsoft\WiX\v3.x\Wix.targets</WixTargetsPath>
    </PropertyGroup>
    <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|x86' ">
        <OutputPath>bin\$(Configuration)\</OutputPath>
        <IntermediateOutputPath>obj\$(Configuration)\</IntermediateOutputPath>
        <DefineConstants>Debug;AssemblyVersionMajor=$(AssemblyVersionMajor);AssemblyVersionMinor=$(AssemblyVersionMinor);AssemblyVersionBuild=$(AssemblyVersionBuild);AssemblyDescription=$(AssemblyDescription);AssemblyProduct=$(AssemblyProduct);AssemblyCompany=$(AssemblyCompany)</DefineConstants>
        <SuppressValidation>False</SuppressValidation>
    </PropertyGroup>
    <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|x86' ">
        <OutputPath>bin\$(Configuration)\</OutputPath>
        <IntermediateOutputPath>obj\$(Configuration)\</IntermediateOutputPath>
        <DefineConstants>AssemblyVersionMajor=$(AssemblyVersionMajor);AssemblyVersionMinor=$(AssemblyVersionMinor);AssemblyVersionBuild=$(AssemblyVersionBuild);AssemblyDescription=$(AssemblyDescription);AssemblyProduct=$(AssemblyProduct);AssemblyCompany=$(AssemblyCompany)</DefineConstants>
    </PropertyGroup>

然后在.wxi文件中我有这个：

<?define MajorVersion="$(var.AssemblyVersionMajor)" ?>
<?define MinorVersion="$(var.AssemblyVersionMinor)" ?>
<?define BuildVersion="$(var.AssemblyVersionBuild)" ?>
<?define VersionNumber="$(var.MajorVersion).$(var.MinorVersion).$(var.BuildVersion)" ?>

最后在我的Product.wxs中：

<?include Definitions.wxi ?>
<Product Id="$(var.GuidProduct)" Name="$(var.AssemblyProduct) $(var.VersionNumber)" Language="!(loc.LANG)"
         Version="$(var.VersionNumber)" Manufacturer="$(var.AssemblyCompany)" UpgradeCode="$(var.GuidUpgrade)">
    <Package Id="$(var.GuidPackage)" InstallerVersion="301" Compressed="yes" InstallScope="perMachine"
             Keywords="!(loc.Keywords)" Description="$(var.AssemblyProduct)" Comments="$(var.AssemblyDescription)" />

Answer 4

我刚刚在google上找到了这个，可能有所帮助：

http://msdn.microsoft.com/en-us/library/system.reflection.assemblyname.version%28v=VS.90%29.aspx

特别地：

//For AssemblyFileVersion
Assembly asm = Assembly.GetExecutingAssembly();
FileVersionInfo fvi = FileVersionInfo.GetVersionInfo(asm.Location);
string version = fvi.FileVersion
//For AssemblyVersion
string revision = Assembly.GetExecutingAssembly().GetName().Version.Revision;

Answer 5

如果您希望能够以100％的准确率处理AssemblyInfo文件，则可以使用C＃任务+ Roslyn。

public class ReadAssemblyInfo : Task {
    [Required]
    public string AssemblyInfoFilePath { get; set; }

    [Output]
    public TaskItem AssemblyVersion { get; set; }

    [Output]
    public TaskItem AssemblyInformationalVersion { get; set; }

    [Output]
    public TaskItem AssemblyFileVersion { get; set; }

    public override bool Execute() {
        using (var reader = new StreamReader(AssemblyInfoFilePath)) {
            var text = reader.ReadToEnd();

            var tree = CSharpSyntaxTree.ParseText(text);
            var root = (CompilationUnitSyntax)tree.GetRoot();

            var attributeLists = root.DescendantNodes().OfType<AttributeListSyntax>();
            foreach (var p in attributeLists) {
                foreach (var attribute in p.Attributes) {
                    var identifier = attribute.Name as IdentifierNameSyntax;

                    if (identifier != null) {
                        var value = ParseAttribute("AssemblyInformationalVersion", identifier, attribute);
                        if (value != null) {
                            SetMetadata(AssemblyInformationalVersion = new TaskItem(value.ToString()), value);
                            break;
                        }

                        value = ParseAttribute("AssemblyVersion", identifier, attribute);
                        if (value != null) {
                            SetMetadata(AssemblyVersion = new TaskItem(value.ToString()), value);
                            break;
                        }

                        value = ParseAttribute("AssemblyFileVersion", identifier, attribute);
                        if (value != null) {
                            SetMetadata(AssemblyFileVersion = new TaskItem(value.ToString()), value);
                            break;
                        }
                    }
                }
            }
        }

        return !Log.HasLoggedErrors;
    }

    private void SetMetadata(TaskItem taskItem, Version version) {
        taskItem.SetMetadata(nameof(version.Major), version.Major.ToString());
        taskItem.SetMetadata(nameof(version.Minor), version.Minor.ToString());
        taskItem.SetMetadata(nameof(version.Build), version.Build.ToString());
        taskItem.SetMetadata(nameof(version.Revision), version.Revision.ToString());
    }

    private static Version ParseAttribute(string attributeName, IdentifierNameSyntax identifier, AttributeSyntax attribute) {
        if (identifier.Identifier.Text.IndexOf(attributeName, StringComparison.Ordinal) >= 0) {
            AttributeArgumentSyntax listArgument = attribute.ArgumentList.Arguments[0];

            var rawText = listArgument.Expression.GetText().ToString();
            if (!string.IsNullOrWhiteSpace(rawText)) {
                rawText = rawText.Replace("\"", "");
                Version version;
                if (Version.TryParse(rawText, out version)) {
                    return version;
                }
            }
        }
        return null;
    }
}

Answer 6

~~您可以使用MSBuild.Community.Tasks.AssemblyInfo.AssemblyVersion从AssemblyInfo.cs访问AssemblyVersion和AssemblyFileVersion。~~

确实，此任务只能用于设置版本。

也许this post很有用。

Answer 7

我使用MSBuild.Community.Tasks中的RegexMatch任务。

您可以将匹配的输出写入项目组，但是如果您想将其读入3个属性，如上所述，则会优先选择自定义任务。

Answer 8

唯一的解决方案是编写自定义构建任务，并在代码中手动解析版本号。

如何从assemblyInfo.cs中读取assemblyversion？
