Delegate.CreateDelegat 抛出异常：方法绑定失败

Question

异常：
System.ArgumentException:绑定到目标方法时出错
PS：MenuItem_Clicked 方法通过反射方式已经可以调用
代码:
绑定到Delegate
string methodName = "MenuItem_Clicked";
MethodInfo menuItemClicked = funType.GetMethod(methodName);
if (menuItemClicked == null)
throw new MethodException(funType.FullName+":"+methodName);

Delegate menuItemHandler = Delegate.CreateDelegate(typeof(EventHandler),item, menuItemClicked,true);
item.GetType().GetEvent("Click").AddEventHandler(item, menuItemHandler);

要绑定的方法
public void MenuItem_Clicked(Object sender, EventArgs e)
{

}
