在事件处理程序中解析Sender [英] Resolve Sender in event handler

问题描述

亲爱的朋友

i有一个类似

dear friends
i have a class like

class1{
int id;
string name;
public System.Windows.Forms.Timer TimerObj = new System.Windows.Forms.Timer();
}

然后创建对象

then create object

class1 Obj = new class1();

Obj.id=1;
Obj.name="AA";
TimerObj.Interval = 1000;
Obj.TimerObj.Tick += new EventHandler(Timer_Tick);

我希望在EventHandler中访问Obj

and i want to access Obj in EventHandler

private void Timer_Tick(object sender, EventArgs e)
{
// ??????  HOW I CAN ACCESS CLASS1 OBJ FROM SENDER
((Timer)sender).
}

谢谢

thanks

推荐答案

尝试：

Try:

    Obj.id=1;
    Obj.name="AA";
    TimerObj.Interval = 1000;
    TimerObj.Tag = Obj;
    Obj.TimerObj.Tick += new EventHandler(Timer_Tick);
    ...
private void Timer_Tick(object sender, EventArgs e)
    {
    Timer t = sender as Timer;
    if (t != null)
       {
       class1 c = t.Tag as class1;
       if (c != null)
          {
          ...
          }
       }
    }
