WPF 动态加载嵌入主程序的DLL

WPF 动态加载嵌入主程序的DLL，好处是节省文件数量，坏处是启动影响加载速度。

首先将DLL添加进项目，选择添加现有项，设置生成操作为“嵌入资源”。

代码：

    public App()
    {   
        
        AppDomain.CurrentDomain.AssemblyResolve += CurrentDomain_AssemblyResolve;
 
    }

    private Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
    {
        if (args.Name.Contains("HandyControl"))
        {
            string resourceName = $"TestWebview2.HandyControl.dll"; // 修改为你的命名空间加DLL名  
            using (Stream stream = Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName))
            {
                if (stream == null) return null;

                byte[] assemblyData = new byte[stream.Length];
                stream.Read(assemblyData, 0, assemblyData.Length);
                return Assembly.Load(assemblyData);
            }
        }
        Debug.Print("--------"+args.Name);
        return null;
    }
}
