问题描述

有没有一种方法(文本或图形)来查看 NuGet 包之间的依赖关系层次结构?

Is there a way, either textual or graphical, to view the hierarchy of dependencies between NuGet packages?

推荐答案

类似于@neil-barnwell 解决方案，但适用于 NuGet.Core 2.7+

Like @neil-barnwell solution, but works with NuGet.Core 2.7+

Install-Package NuGet.Core

这里是代码

using System;
using System.Linq;
using System.Runtime.Versioning;
using System.IO;
using NuGet;

public class Program
{
    public static void Main(string[] args)
    {
        var frameworkName = new FrameworkName(".NETFramework, Version=4.0");

        // var packageSource = "https://www.nuget.org/api/v2/";
        var packageSource = Path.Combine(Environment.GetEnvironmentVariable("LocalAppData"), "NuGet", "Cache");

        var repository = PackageRepositoryFactory.Default.CreateRepository(packageSource);
        const bool prerelease = false;

        var packages = repository.GetPackages()
            .Where(p => prerelease ? p.IsAbsoluteLatestVersion : p.IsLatestVersion)
            .Where(p => VersionUtility.IsCompatible(frameworkName, p.GetSupportedFrameworks()));

        foreach (IPackage package in packages)
        {
            GetValue(repository, frameworkName, package, prerelease, 0);
        }

        Console.WriteLine();
        Console.WriteLine("Press Enter...");
        Console.ReadLine();
    }

    private static void GetValue(IPackageRepository repository, FrameworkName frameworkName, IPackage package, bool prerelease, int level)
    {

        Console.WriteLine("{0}{1}", new string(' ', level * 3), package);
        foreach (PackageDependency dependency in package.GetCompatiblePackageDependencies(frameworkName))
        {
            IPackage subPackage = repository.ResolveDependency(dependency, prerelease, true);
            GetValue(repository, frameworkName, subPackage, prerelease, level + 1);
        }
    }
}
