调用：

RunAsyncMethod(new AsyncBeginInvoke(BusinessHandler.Handle), new AsyncCallback(BusinessHandler.Callback), data);

定义：

public delegate void AsyncBeginInvoke(dynamic data);
public delegate void AsyncEndInvoke(dynamic result);
public void RunAsyncMethod(dynamic method, dynamic callback, dynamic data)
{
IAsyncResult binvoke = method.BeginInvoke(data, callback, null);
method.EndInvoke(binvoke);
}
