我创建了一个WinForm并添加了动态按钮,我如何处理它的事件
public static void Notify()
{
var line = 3;
Form fm = new Form();
fm.Text = "Hello!";
fm.ShowInTaskbar = false;
fm.ShowIcon = false;
fm.MinimizeBox = false;
fm.MaximizeBox = false;
fm.FormBorderStyle = FormBorderStyle.FixedToolWindow;
fm.TopMost = true;
fm.ClientSize = new Size(150, 75 * line/2);
Rectangle workingArea = Screen.PrimaryScreen.WorkingArea;
int left = workingArea.Width - fm.Width-5;
int top = workingArea.Height - fm.Height-4;
fm.Location = new Point(left, top);
fm.StartPosition = FormStartPosition.Manual;
var buttomArray = new Button[line];
for (int i = 0; i < line; i++)
{
buttomArray[i] = new Button();
buttomArray[i].Text = "Button " + (i + 1);
buttomArray[i].Location = new Point(10,30*(i+1) - 16);
buttomArray[i].Size = new Size(130,25);
fm.Controls.AddRange(new Control[] { buttomArray[i] });
}
fm.Show();
}
当我点击不同的按钮时,我希望能够做一些不同的事情(也许我可以使用“名称”作为标识符?)

只需指定Click处理程序:
for (int i = 0; i < 10; i++)
{
var btn = new Button();
btn.Text = "Button " + i;
btn.Location = new Point(10, 30 * (i + 1) - 16);
btn.Click += (sender, args) =>
{
// sender is the instance of the button that was clicked
MessageBox.Show(((Button)sender).Text + " was clicked");
};
Controls.Add(btn);
}

订阅Button.Click事件。当您处于创建循环中时,将要在单击处理程序中使用的数据附加到Tag属性。
for (int i = 0; i < line; i++)
{
buttomArray[i] = new Button();
buttomArray[i].Tag=i;
.....
在点击处理程序中,发件人将是Button(您可以投射到它),标签将包含您的值。
Button btn=(Button)sender;
int value=(int)btn.Tag;
Tag-property接受任何类型。因此,您可以附加任何值。
