如何以编程方式安装NuGet包？ [英] How to programmatically install a NuGet package?

问题描述

我想以编程方式将NuGet包安装到项目中，并更新.csproj文件和packages.config文件。

现在我可以从Nuget添加DLL to package.config，但我无法更新.cs proj文件。

 string packageID =Newtonsoft.json; 
 var sourceUri = new Uri（https://packages.nuget.org/api/v2）; 
 
 //返回一个IPackage 
 var package = GetNugetPackage（packageID，sourceUri）; 
 
 IPackageRepository sourceRepository = PackageRepositoryFactory.Default.CreateRepository（sourceUri.ToString（））; 
 
 string packagesPath =../../TestFiles/packages; 
 PackageManager packageManager = new PackageManager（sourceRepository，packagesPath）; 
 
 packageManager.InstallPackage（packageID，SemanticVersion.Parse（package.Version.ToFullString（）））; 
 
 // ----更新'packages.config'文件---- 
 var packageReferenceFile = new PackageReferenceFile（../../ TestFiles / packages.config） ; 
 
 //获取要添加的当前项目的目标框架 - > package.config文件中的targetframework =net452属性
 var currentTargetFw = Assembly.GetExecutingAssembly（）。GetCustomAttributes（typeof（TargetFrameworkAttribute），false）; 
 var targetFrameworkAttribute =（（TargetFrameworkAttribute []）currentTargetFw）.FirstOrDefault（）; 
 
 //更新packages.config文件
 packageReferenceFile.AddEntry（package.GetFullName（），SemanticVersion.Parse（package.Version.ToFullString（）），false，new FrameworkName（targetFrameworkAttribute。 FrameworkName））;

I want to programmatically install a NuGet package to a project, and update the .csproj file, and the packages.config file.

Right now i can add DLL from Nuget to package.config,but i couldn't update .cs proj file.

string packageID = "Newtonsoft.json";
var sourceUri = new Uri("https://packages.nuget.org/api/v2");

// Return an IPackage
var package = GetNugetPackage(packageID, sourceUri);

IPackageRepository sourceRepository = PackageRepositoryFactory.Default.CreateRepository(sourceUri.ToString());

string packagesPath = "../../TestFiles/packages";
PackageManager packageManager = new PackageManager(sourceRepository, packagesPath);

packageManager.InstallPackage(packageID, SemanticVersion.Parse(package.Version.ToFullString()));

// ---- Update the ‘packages.config’ file ----
var packageReferenceFile = new PackageReferenceFile("../../TestFiles/packages.config");

// Get the target framework of the current project to add --> targetframework="net452" attribute in the package.config file
var currentTargetFw = Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(TargetFrameworkAttribute), false);
var targetFrameworkAttribute = ((TargetFrameworkAttribute[])currentTargetFw).FirstOrDefault();

// Update the packages.config file    
packageReferenceFile.AddEntry(package.GetFullName(), SemanticVersion.Parse(package.Version.ToFullString()), false, new FrameworkName(targetFrameworkAttribute.FrameworkName));
