C# dllimport 备忘录

dllImport的入口点问题

通过Dependencies查询Dll对应方法的EntryPoint

然后在dllimport的attribute中显式申明EntryPoint

[DllImport("demo.dll", SetLastError = true,EntryPoint ="[email protected]@Gfeit@@[email protected]")]
        public static extern IntPtr DemoManager();

导入类方法的问题

最好的方式还是使用C++构造wrapper，然后通过windowsApi的方式调用Pinvoke
