有一个用delphi写的dll导出方法: DllGetClassObject: function(const CLSID, IID: TGUID; var Obj): HResult; 标准调用;
我需要在 c# 中编写等效方法作为委托。它应该是什么样子?
像这样:
[UnmanagedFunctionPointer(CallingConvention.StdCall)]
public delegate uint DllGetClassObjectDelegate(
[MarshalAs(UnmanagedType.LPStruct)]
Guid rclsid,
[MarshalAs(UnmanagedType.LPStruct)]
Guid riid,
[MarshalAs(UnmanagedType.IUnknown, IidParameterIndex=1)]
out object ppv
);
