APlayerCaller.dll创建基本已写,创建依然失败。请求帮助。

// button1 事件是创建
// 事件写在按钮下后才发现,只要创建后就会程序意外结束!
  1. //Form1.cs 部分代码
  2. public delegate void fun3(int l1, int l2, int l3);//声明委托
  3.        private void button1_Click(object sender, EventArgs e)
  4.         {
  5.            // new 方法并取地址,以下方同。
  6.             fun3 DOnMessage = new fun3(OnMessage);
  7.             POnMessage = Marshal.GetFunctionPointerForDelegate(DOnMessage);

本机已用易语言测试过,C#嵌入COM组件(aplayer控件)都一切正常。求助!

对照 APlayerCaller.dll 的源代码(论坛有下),检查各个事件响应函数参数的数目和数据类型是否有不一致的,很有可能是这个问题导致的崩溃。
