Question

设置的长度始终为0，因此代码跳转到if语句的返回，这不应该是，我无法弄清楚为什么，poperty被设置为“TreatWarningsAsErrors” 我需要比较propertyName string中指定的节点的值。

public string CheckSettings(XElement propertyGroup, string groupName, string propertyName)
    {
        var setting = (from doc in propertyGroup?.Descendants(propertyName) select doc).ToArray();

        if (setting.Length == 0)
        {
            return groupName + ": " + propertyName + " is missing";
        }

        var allOk = setting.All(n => n.Value.Equals("true", StringComparison.InvariantCultureIgnoreCase));
        return allOk ? null : groupName + ": " + propertyName + " has wrong state.";
    }

示例xml

 <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">
<DebugSymbols>true</DebugSymbols>
<DebugType>full</DebugType>
<Optimize>false</Optimize>
<OutputPath>..\..\..\..\..\..\Bin\AlfaStandardXmlManifest\</OutputPath>
<DefineConstants>DEBUG;TRACE</DefineConstants>
<ErrorReport>prompt</ErrorReport>
<WarningLevel>4</WarningLevel>
<UseVSHostingProcess>false</UseVSHostingProcess>
<DocumentationFile>..\..\..\..\..\..\Bin\AlfaStandardXmlManifest\AlfaStandardXmlManifest.XML</DocumentationFile>
<CodeAnalysisRuleSet>..\..\..\..\Build\FxCopSoftship_ZeroTolerance.ruleset</CodeAnalysisRuleSet>
<RunCodeAnalysis>false</RunCodeAnalysis>
<TreatWarningsAsErrors>false</TreatWarningsAsErrors>
 </PropertyGroup>

添加了xml加载和settigns检查调用：

 var xmlDoc = XDocument.Load(projectFilePath);
        XNamespace nameSpace = xmlDoc.Root?.Name.Namespace;
        if (xmlDoc.Root != null)
        {
            var groups = xmlDoc.Root.Descendants(nameSpace + "PropertyGroup").ToArray();

            foreach (var group in groups)
            {
                result.Add(CheckSettings(group, GroupName(group), "RunCodeAnalysis"));
                result.Add(CheckSettings(group, GroupName(group), "TreatWarningsAsErrors"));

以下是调试器为组提供的内容

    <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' " xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <DebugSymbols>true</DebugSymbols>
  <DebugType>full</DebugType>
  <Optimize>false</Optimize>
  <OutputPath>..\..\..\..\..\..\Bin\AlfaStandardXmlManifest\</OutputPath>
  <DefineConstants>DEBUG;TRACE</DefineConstants>
  <ErrorReport>prompt</ErrorReport>
  <WarningLevel>4</WarningLevel>
  <UseVSHostingProcess>false</UseVSHostingProcess>
  <DocumentationFile>..\..\..\..\..\..\Bin\AlfaStandardXmlManifest\AlfaStandardXmlManifest.XML</DocumentationFile>
  <CodeAnalysisRuleSet>..\..\..\..\Build\FxCopSoftship_ZeroTolerance.ruleset</CodeAnalysisRuleSet>
  <RunCodeAnalysis>false</RunCodeAnalysis>
  <TreatWarningsAsErrors>false</TreatWarningsAsErrors>
</PropertyGroup>

Answer 1

大多数MSBuild项目文件都有一个XML命名空间（根元素中为xmlns="..."），它适用于XML中的所有名称。

您需要在元素名称中包含此命名空间：

XNamespace ns = "...";
XName name = ns + "...";

Answer 2

好吧，像SLaks说的那样，问题在于命名空间。在CheckSettings中，在Descendants中你缺少命名空间：

XNamespace nameSpace = propertyGroup.Name.Namespace;
var setting = (from doc in propertyGroup?.Descendants(nameSpace + propertyName) select doc).ToArray();

c＃数组的长度始终为0
