Merging a WPF application into a single EXE

Merging a WPF application into a single EXE

第一步，找到项目文件下的 .csprojc 文件，用文本编辑器打开它，并找到下面这行：
<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />

把下面的 XML 粘贴到文件中，然后保存并在 Visual Studio 中重载：
<Target Name="AfterResolveReferences">
  <ItemGroup>
    <EmbeddedResource Include="@(ReferenceCopyLocalPaths)" Condition="'%(ReferenceCopyLocalPaths.Extension)' == '.dll'">
      <LogicalName>%(ReferenceCopyLocalPaths.DestinationSubDirectory)%(ReferenceCopyLocalPaths.Filename)%(ReferenceCopyLocalPaths.Extension)</LogicalName>
    </EmbeddedResource>
  </ItemGroup>
</Target>

粘贴后的文件应该差不多长这样：
</ItemGroup>
<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />
<Target Name="AfterResolveReferences">
  <ItemGroup>
    <EmbeddedResource Include="@(ReferenceCopyLocalPaths)" Condition="'%(ReferenceCopyLocalPaths.Extension)' == '.dll'">
      <LogicalName>%(ReferenceCopyLocalPaths.DestinationSubDirectory)%(ReferenceCopyLocalPaths.Filename)%(ReferenceCopyLocalPaths.Extension)</LogicalName>
    </EmbeddedResource>
  </ItemGroup>
  <!-- To modify your build process, add your task inside one of the targets
       Other similar extension points exist, see Microsoft.Common.targets.
  <Target Name="BeforeBuild">
  </Targe>
  <Targer Name="AfterBuild">
  </Target>
  -->
  </Project>
  
第二步，你需要在你的项目中新建一个文件（e.g. Program.cs）然后把下列代码加入（根据你的程序命名/结构）：
[STAThread]
public static void Main()
{
    AppDomain.CurrentDomain.AssemblyResolve += OnResolveAssembly;
 
    App.Main(); // Run WPF startup code.
}
 
private static Assembly OnResolveAssembly(object sender, ResolveEventArgs e)
{
    var thisAssembly = Assembly.GetExecutingAssembly();
 
    // Get the Name of the AssemblyFile
    var assemblyName = new AssemblyName(e.Name);
    var dllName = assemblyName.Name + ".dll";
 
    // Load from Embedded Resources - This function is not called if the Assembly is already
    // in the same folder as the app.
    var resources = thisAssembly.GetManifestResourceNames().Where(s => s.EndsWith(dllName));
    if (resources.Any())
    {
 
        // 99% of cases will only have one matching item, but if you don't,
        // you will have to change the logic to handle those cases.
        var resourceName = resources.First();
        using (var stream = thisAssembly.GetManifestResourceStream(resourceName))
        {
            if (stream == null) return null;
            var block = new byte[stream.Length];
 
            // Safely try to load the assembly.
            try
            {
                stream.Read(block, 0, block.Length);
                return Assembly.Load(block);
            }
            catch (IOException)
            {
                return null;
            }
            catch(BadImageFormatException)
            {
                return null;
            }
        }
    }
 
    // in the case the resource doesn't exist, return null.
    return null;
}

第三步，设定你的项目属性，确定程序的启动窗体（Startup object）是上面的这段代码。
