如何使用托管C#应用程序打包托管C#DLL而不留下文件？

我已经阅读了另外两个线程，它们在运行时从应用程序中提取dll。其中一种方法使用当前的Windows临时目录保存dll，但它是非托管dll，必须在运行时使用

DllImport

导入。假设我的托管dll已导出到临时目录，如何将该托管程序集正确链接到我当前的MSVC项目？

您根本不需要保存到临时目录。只需将托管dll作为“嵌入式资源”放在项目中即可。然后钩住Appdomain.AssemblyResolve事件，在事件中，将资源作为字节流加载，并从流中加载程序集并返回它

示例代码：

// Windows Forms:
// C#: The static contructor of the 'Program' class in Program.cs
// VB.Net: 'MyApplication' class in ApplicationEvents.vb (Project Settings-->Application Tab-->View Application Events)
// WPF:
// The 'App' class in WPF applications (app.xaml.cs/vb)

static Program() // Or MyApplication or App as mentioned above
{
    AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve);
}

static Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
{
    if (args.Name.Contains("Mydll"))
    {
        // Looking for the Mydll.dll assembly, load it from our own embedded resource
        foreach (string res in Assembly.GetExecutingAssembly().GetManifestResourceNames())
        {
            if(res.EndsWith("Mydll.dll"))
            {
                Stream s = Assembly.GetExecutingAssembly().GetManifestResourceStream(res);
                byte[] buff = new byte[s.Length];
                s.Read(buff, 0, buff.Length);
                return Assembly.Load(buff);
            }
        }
    }
    return null;
}
