这篇博客介绍了如何在Visual Studio 2008中使用.NET 3.5将DLL库嵌入到EXE应用程序中，主要参考了两个资源链接，提供了在项目中添加现有项以及在Main函数前添加特定函数的方法。

对于vs2008 使用.net3.5的情况，可以直接在项目上添加现用项，Main函数最前添加以下函数

    //格式1
    //!!! for load embedded dll: (2) implement this handler
    System.Reflection.Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
    {
        string dllName = args.Name.Contains(",") ? args.Name.Substring(0, args.Name.IndexOf(',')) : args.Name.Replace(".dll", "");

        dllName = dllName.Replace(".", "_");

        if (dllName.EndsWith("_resources")) return null;

        System.Resources.ResourceManager rm = new System.Resources.ResourceManager(GetType().Namespace + ".Properties.Resources", System.Reflection.Assembly.GetExecutingAssembly());

        byte[] bytes = (byte[])rm.GetObject(dllName);

        return System.Reflection.Assembly.Load(bytes);
    }
    
    //格式2
        // 框架加载dll失败后执行，手动加载dll
    AppDomain.CurrentDomain.AssemblyResolve += (sender, senderArgs) =>
    {
        // 当前程序集
        var executingAssembly = Assembly.GetExecutingAssembly();
        // 当前程序集名称
        var assemblyName = new AssemblyName(executingAssembly.FullName).Name;
        // dll名称
        var dllName = new AssemblyName(senderArgs.Name).Name;
        // 待加载dll路径，指向当前程序集资源文件中dll路径。* 根据程序结构调整，使其正确指向dll
        var dllUri = assemblyName + "." + dllName + ".dll";
        // 加载dll
        using (var resourceStream = executingAssembly.GetManifestResourceStream(dllUri))
        {
            var assemblyData = new Byte[resourceStream.Length];
            resourceStream.Read(assemblyData, 0, assemblyData.Length);
            //return Assembly.Load(assemblyData); //加载dll
            var valrt = Assembly.Load(assemblyData); //加载dll
            return valrt;
        }
    };

另外可以把dll都放到一个文件夹里，然后添加引用，并设置属性为"嵌入的资源"

改好的代码备份一下
