Question

I am new to Windows Phone 7.
I clicked one button and got:

private void button1_click(object sender, RoutedEventArgs e)
{

}

Is it possible get the tag property and object type of sender?

Answer 1

You can get the Type by using the GetType() method:

sender.GetType();

If you want to cast it as a button, you can do this.

var myButton = sender as Button;
if(myButton != null)
    var buttonTag = myButton.Tag;

Using as instead of (Button)sender means that instead of an exception being thrown if it can’t be cast as a Button, it will simply return null. We can then check if it’s null and, if it’s not null, we can access its Tag property.
