利用反射查找绑定事件

1.手动创建一个控件

2.反射查找事件，绑定事件到控件 

private EventHandler BindEvent(ToolStripMenuItem Toostrip,string EventName)
{
    PropertyInfo propertyInfo = (typeof(ToolStripMenuItem)).GetProperty("Events", BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.IgnoreReturn | BindingFlags.IgnoreCase);
            
    EventHandlerList eventHandlerList = (EventHandlerList)propertyInfo.GetValue(Toostrip, null);

    FieldInfo fieldInfo = (typeof(ToolStripMenuItem)).GetField("EventClick", BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.FlattenHierarchy);
         
    Delegate d = eventHandlerList[fieldInfo.GetValue(null)];
    if (d != null)
    {
        foreach (Delegate de in d.GetInvocationList())
        { 
                    
            //textBox1.Text += de.Method.Name;
            if (d.Method.Name == EventName)
            {
                return (EventHandler)d;
            }
        }
    }
    return null;
}
