DllImport 动态类

[DllImport("XXX.dll", EntryPoint = "PGIP_startup", SetLastError = true, CharSet = CharSet.Unicode, CallingConvention = CallingConvention.Cdecl)]
private  static extern int _PGIP_Startup([MarshalAs(UnmanagedType.LPArray)]string[] szPluginDirs, int nCount);

如果XXX.dll还有连接别的动态类，并挂到iis上的时候，可能需要加CallingConvention = CallingConvention.Cdecl
