In my C# Windows Forms form I have some buttons which are dynamically generated. I assigned the following method on the click event. Is it possible to get the name of the button from which the event is triggered?
private void btnBrowsDoc_Click(object sender, EventArgs e)
{

openFileDialog1.FileName;

return;

推荐答案
您可以使用 sender 参数.那就是引发点击事件的控件(本例中的按钮):
You can use the sender argument. That is the Control (the button in this case) that has raised the click event:
var button = (Button)sender;
button.Name ...
注意:如果您已将其他控件(例如面板等)订阅到同一事件处理程序，您可以使用 as 操作符检查发送者是否为按钮:
N.B.: In case you have subscribed other controls (e.g. panels, etc.) to the same event handler, you can check if the sender is a button using the asoperator:
var button = sender as Button;
if (button != null)
{
button.Name ...
...
}
