【Winform】所有的dll都打包到一个exe里

整个程序依赖很多dll

编译之后，Debug目录下会存在各种dll，比较乱。 

想要的效果是，最后只有一个exe，发给别人也方便

下面直接说方法

1、修改 csproj 文件，在 </Project> 节点上面，添加下面的节点

  <Target Name="AfterResolveReferences">
    <ItemGroup>
      <EmbeddedResource Include="@(ReferenceCopyLocalPaths)" Condition="'%(ReferenceCopyLocalPaths.Extension)' == '.dll'">
        <LogicalName>%(ReferenceCopyLocalPaths.DestinationSubDirectory)%(ReferenceCopyLocalPaths.Filename)%(ReferenceCopyLocalPaths.Extension)</LogicalName>
      </EmbeddedResource>
    </ItemGroup>
  </Target>


  <Target Name="DeleteOtherFile" AfterTargets="AfterBuild">
    <ItemGroup>
      <OtherFiles Include="$(OutputPath)\*" Exclude="$(OutputPath)\$(AssemblyName).exe" />
    </ItemGroup>
    <Delete Files="@(OtherFiles)" />
  </Target>

 2、修改Program方法，反射加载资源

using System;
using System.Collections.Generic;
using System.Globalization;
using System.Linq;
using System.Reflection;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WindowsFormsApp6
{
    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            AppDomain.CurrentDomain.AssemblyResolve += OnResolveAssembly;
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }

        private static Assembly OnResolveAssembly(object sender, ResolveEventArgs args)
        {
            var executingAssembly = Assembly.GetExecutingAssembly();
            var assemblyName = new AssemblyName(args.Name);

            var path = assemblyName.Name + ".dll";
            if (assemblyName.CultureInfo.Equals(CultureInfo.InvariantCulture) == false)
                path = $@"{assemblyName.CultureInfo}\{path}";

            using (var stream = executingAssembly.GetManifestResourceStream(path))
            {
                if (stream == null) 
                    return null;

                var assemblyRawBytes = new byte[stream.Length];
                stream.Read(assemblyRawBytes, 0, assemblyRawBytes.Length);
                return Assembly.Load(assemblyRawBytes);
            }
        }
    }
}

编译一下看看效果，已经只剩下一个大小几M的exe文件了，快乐的发给别人就好了。
