动态生成一批btton 控件和时间Timer组件取名称问题
C#2.0 winform中我动态生成一批btton 控件和时间Timer组件生成事件如下:
btnArray[n].Click += new System.EventHandler(ClickButton);
timArray[n].Tick += new System.EventHandler(timerTick);
请问大家怎能在事件public void ClickButton(object sender, System.EventArgs e)和 private void timerTick(Object sender, System.EventArgs e)取得他们的名称??谢谢 --------------------编程问答-------------------- Button btn=(Button)sender
btn.Name

http://feiyun0112.cnblogs.com/ --------------------编程问答-------------------- 你在动态生成时最好也给它们赋个名称,这样feiyun0112代码才有意义 --------------------编程问答-------------------- 有名称的啦，现在是Button单击的时候要知道是那个按钮
还是时间组件 --------------------编程问答-------------------- 用一楼的方法
在buttton的onclick事件中。
Button btn=(Button)sender ；
string a=btn.Name;
--------------------编程问答-------------------- ((Button)sender).Name.ToString() --------------------编程问答-------------------- 取sender, --------------------编程问答-------------------- 好奇怪我取和Name值为空,怎解决 --------------------编程问答-------------------- 代码我发一下,以免大家误解

} --------------------编程问答-------------------- 取名称的目的是什么？
你可以使用((Button)sender).Text等属性来判断
也可以用Tag来记录下标
btnArray[n].Tag = n;
btnArray[n].Click += new System.EventHandler(ClickButton);
public void ClickButton(object sender, System.EventArgs e)--------------------编程问答-------------------- 你生成Button的时候,没有赋名称呀.应该如下:
{
//btnArray[(int)((Button)sender).Tag];
}
case "btn ": // anyControl = btn to Add Button
{
// assign number of controls
btnArray = new System.Windows.Forms.Button[cNumber + 1];
for (int i = 0; i < cNumber + 1; i++)
{
// Initialize one variable
btnArray[i] = new System.Windows.Forms.Button();
btnArray[i].Name = "btn"+i.ToString() ;
}
break;
}

btnArray[i] = new System.Windows.Forms.Button();
btnArray[i].Name = "btn "+i.ToString();
}
break;
}
--------------------编程问答-------------------- 楼上是对的,但是Timer是没有Name这个属性的
其他我最想要就是知道那个Timer
private void timerTick(Object sender, System.EventArgs e)
{
string n = ((System.Windows.Forms.Timer)sender).Site.Name.ToString();
MessageBox.Show( "You have clicked button ");
}
--------------------编程问答-------------------- 我要取得是那个时间Timer控件的Tick然后再去执行另一个传入参数到另一个函数执行如下
private void timerTick(Object sender, System.EventArgs e)
{
int yy=取得Timer控件;
CheckID(yy);
}
--------------------编程问答-------------------- Timer也是有Name属性的呀。
--------------------编程问答-------------------- 1、你在创建Timer的时候，把Name赋上;
2、取法跟Button是一样的;
--------------------编程问答-------------------- wisest(无影无忠)你试过没有,我试过了是没有的 --------------------编程问答-------------------- 不信你在代码里写 --------------------编程问答-------------------- 哦，我没看清楚。
那你这样子做吧
创建Timer:
Timer t = new Timer(100);
t.tag="12345";
接下去，你会做了吧？ --------------------编程问答-------------------- 谢谢,搞定了,怎么结贴给分
