C #的一个小问题...

[irearn]

有一个form,里面有一个panel,我一单击button，panel里生成了两个label，代码如下：

private void button1_Click(object sender, EventArgs e)
{
int n = 2;
Label[] la = new Label[n];
for (int i = 0; i < n; i++)
{
la[i] = new Label();
la[i].Text = Convert.ToString(i);
flowLayoutPanel1.Controls.Add(la[i]);
}
}

然后我单击label1（左边那个） 弹出对话框，“你单击了label1”，单击右边那个就是“你单击了label2”。

我知道怎么弹出对话框，我想弄明白的是，这两个label是程序后来生成的，如何对它们编辑这样的事件。

通过事务绑定
不过你用循环生成的比较麻烦

private void button1_Click(object sender, EventArgs e)
{
int n = 2;
Label[] la = new Label[n];
for (int i = 0; i < n; i++)
{
la[i] = new Label();
la[i].Text = Convert.ToString(i);
flowLayoutPanel1.Controls.Add(la[i]);
la[i].Click+=(obj,eve)=>MessageBox.Show("你单击了label"+i);//C#3.0语法。
//也可以根据控件名来处理：MessageBox.Show(obj.ToString());//稍微处理一下就行了
}
}

private void button1_Click(object sender, EventArgs e)
{
int n = 2;
Label[] la = new Label[n];
for (int i = 0; i < n; i++)
{
la[i] = new Label();
la[i].Text = Convert.ToString(i);
la[i].Click+=new System.EventHandler(Label_Click);//正统语法
flowLayoutPanel1.Controls.Add(la[i]);
}
}

private void Label_Click(object sender, EventArgs e)
{
...
}
