C# 把多个dll合成一个dll

1. Nuget 下载ILMerge
2. 两个工程
   dog为测试工程
   TestIlmerge为准备合并的类库
   
3. 如下图所示，
   由于我们引用下面4个库
   正常生成后，会有TestIlmerge.dll和下面的这4个dll
   
4. 只生成TestIlmerge.dll
   打开工程文件
   
   在最下方加入以下两段

  <Target Name="ILMerge"><Exec Command="$(ILMergeConsolePath) bin\Debug\TestIlmerge.dll /out:bin\Debug\TestIlmerge.dll bin\Debug\Newtonsoft.Json.dll bin\Debug\Emgu.CV.World.dll bin\Debug\Emgu.CV.UI.dll bin\Debug\ZedGraph.dll" /></Target><Target Name="_ProjectRemoveDependencyFiles" AfterTargets="AfterBuild" DependsOnTargets="ILMerge"><ItemGroup><_ProjectDependencyFile Include="bin\Debug\Newtonsoft.Json.dll" /><_ProjectDependencyFile Include="bin\Debug\Emgu.CV.World.dll" /><_ProjectDependencyFile Include="bin\Debug\Emgu.CV.UI.dll" /><_ProjectDependencyFile Include="bin\Debug\ZedGraph.dll" /></ItemGroup><Delete Files="@(_ProjectDependencyFile)" /></Target>

5. 点击生成即可
