子程序定义：

　　  public delegate void CurrentControlListenEvent(string uniqueID, string way = null);        public event CurrentControlListenEvent CurrentControlEvent;        protected void InvokeCurrentControlEvent(string uniqueID, string way = null)        {            if (this.CurrentControlEvent != null)                CurrentControlEvent(this.UniqueID);        }

子程序调用：

InvokeCurrentControlEvent("123456");//或InvokeCurrentControlEvent("123456","del");

父程序定义：

　　　　　　　　　　  Control ctl = LoadControl("~/UserControls/Metadata/ucAttributeValues.ascx");                    ctl.ID = "ucAttributeValues" + (tempLoadPhValueControlCount);                    Type type = ctl.GetType();                    EventInfo currentControlEvent = type.GetEvent("CurrentControlEvent");                    Type tDelegate = currentControlEvent.EventHandlerType;                    MethodInfo miHandler = this.GetType().GetMethod("InvokeControl");                    Delegate d = Delegate.CreateDelegate(tDelegate, this, miHandler);                    MethodInfo addHandler = currentControlEvent.GetAddMethod();                    Object[] addHandlerArgs = { d };                    addHandler.Invoke(ctl, addHandlerArgs);                    //正常非反射的调用方式就一行代码，但有些情况不得不用反射来操作委托的实例                    //ctl.SetCaptureListener(new UserControls_Metadata_ucAttributeValues.CaptureListenEvent(InvokeControl));

委托子程序调用父程序的方法体：

public void InvokeSubtract(string uniqueID)        {            if (this.phCtl.Controls.Count > 0)            {                for (int i = this.phCtl.Controls.Count - 1; i >= 0; i--)                {                    if (phCtl.Controls[i].UniqueID == uniqueID)                    {                        phCtl.Controls[i].Visible = false;                        break;                    }                }            }        }
