需要在.Net Core应用程序中提取并安装最新版本的nugets
Nuget.Core是可用的。但是在.Net Standard的情况下。
希望使用Nuget.Client更新。 How to download a nupkg package from nuget programmatically in .NET Core? 这几乎是相同的模式,但是我无法从该问题中找到相关的答案。
.Net标准实施 How to get nuget package version programmatically from a nuget feed?
需要安装最新版本,这可能在运行一组测试时发生,并且我的块需要更新为最新版本。这样我的测试才能针对最新的nuget版本进行验证

因此,要在给定的.csproj
中正确添加引用,这是我的工作:
var CsprojDoc = new XmlDocument();
CsprojDoc.LoadXml("*your_csproj_content*");
var Nsmgr = new XmlNamespaceManager(CsprojDoc.NameTable);
Nsmgr.AddNamespace("x", "http://schemas.microsoft.com/developer/msbuild/2003");
IPackage packageInfos = GetNugetPackage(packageId, packageRepositoryUri);
XmlNode referenceNode = CsprojDoc.CreateNode(XmlNodeType.Element, "Reference", XmlNamespaceValue);
XmlAttribute includeAttribute = CsprojDoc.CreateAttribute("Include");
var targetFwProfile = CsprojDoc.SelectSingleNode("//x:TargetFrameworkProfile", Nsmgr);
string targetFrameworkProfile = string.Empty;
if (!string.IsNullOrEmpty(targetFwProfile?.InnerXml))
{
targetFrameworkProfile = targetFwProfile.InnerXml;
}
var targetFwAttribute = GetTargetFrameworkFromCsproj();
Regex p = new Regex(@"\d+(\.\d+)+");
Match m = p.Match(targetFwAttribute.FrameworkName);
Version targetFwVersion = Version.Parse(m.Value);
// Get the package's assembly reference matching the target framework from the given '.csproj'.
var assemblyReference =
packageInfos.AssemblyReferences
.Where(a => a.TargetFramework.Identifier.Equals(targetFwAttribute.FrameworkName.Split(',').First()))
.Where(a => a.TargetFramework.Profile.Equals(targetFrameworkProfile))
.Last(a => (a.TargetFramework.Version.Major.Equals(targetFwVersion.Major) && a.TargetFramework.Version.Minor.Equals(targetFwVersion.Minor)) ||
a.TargetFramework.Version.Major.Equals(targetFwVersion.Major));
DownloadNugetPackage(packageInfos.Id, packageRepositoryUri, packagesFolderPath, packageInfos.Version.ToFullString());
string dllAbsolutePath = Path.GetFullPath($"{packagesFolderPath}\\{packageInfos.GetFullName().Replace(' ', '.')}\\{assemblyReference.Path}");
var assemblyInfos = Assembly.LoadFile(dllAbsolutePath);
includeAttribute.Value = $"{assemblyInfos.FullName}, processorArchitecture=MSIL";
referenceNode.Attributes.Append(includeAttribute);
XmlNode hintPathNode = CsprojDoc.CreateNode(XmlNodeType.Element, "HintPath", XmlNamespaceValue);
XmlNode privateNode = CsprojDoc.CreateNode(XmlNodeType.Element, "Private", XmlNamespaceValue);
hintPathNode.InnerXml = $"$(SolutionDir)\\packages\\{assemblyReference.Path}";
privateNode.InnerXml = "True";
referenceNode.AppendChild(hintPathNode);
referenceNode.AppendChild(privateNode);
var itemGroupNode = CsprojDoc.SelectSingleNode("//x:Project/x:ItemGroup/x:Reference", Nsmgr).ParentNode;
itemGroupNode.AppendChild(referenceNode);
这是我的DownloadNugetPackage
方法:
private static void DownloadNugetPackage(string packageId, Uri repoUri, string packagesFolderPath, string version)
{
IPackageRepository packageRepository = PackageRepositoryFactory.Default.CreateRepository(repoUri.ToString());
PackageManager packageManager = new PackageManager(packageRepository, packagesFolderPath);
packageManager.InstallPackage(packageId, SemanticVersion.Parse(version));
}
我的GetTargetFrameworkFromCsproj
public static TargetFrameworkAttribute GetTargetFrameworkFromCsproj()
{
XmlNode targetFrameworkNode = CsprojDoc.SelectSingleNode("//x:TargetFrameworkVersion", Nsmgr);
return new TargetFrameworkAttribute($".NETFramework, Version={targetFrameworkNode.InnerXml}");
}
还有我的GetNugetPackage
方法:
public static IPackage GetNugetPackage(string packageId, Uri repoUri, string version = null)
{
IPackageRepository packageRepository = PackageRepositoryFactory.Default.CreateRepository(repoUri.ToString());
IPackage package;
if (!string.IsNullOrEmpty(version))
{
package = packageRepository.FindPackagesById(packageId).SingleOrDefault(p => p.Version.ToFullString().Equals(version));
}
else
{
package = packageRepository.FindPackagesById(packageId).SingleOrDefault(p => p.IsLatestVersion);
}
return package;
}
注意:这一次,我使用的是官方的NuGet软件包: Nuget.core 2.14 :https://www.nuget.org/packages/NuGet.Core/
注2:当我在
Reference
属性中添加新的processorArchitecture
节点时,我已经硬编码了值:MSIL
如果要对其进行测试,可以对其进行一些调整。
这对我来说很好。
