Question

Imagine a method like this ( in Win Forms):

//First method
private void buttonStart_Click(object sender, EventArgs e)
{
       //I call another method here
       this.GetData(sender, null)
}

//Second method
private void GetData(object sender, EventArgs e)
{
       //how to check IF calling method is buttonStart_Click ???
       if(sender.Equals == buttonStart_Click) 
       {
            //DO BLAH BLAH
       }
}

I hope I was clear, that is I want to know which method is calling ‘GetData’. note I know I can have a global variable and set it to something, but I want to know if there is a DIRECT way to do this?

Thanks.

Answer 1

sender is not going to be buttonStart_Click, it will simply be the button. So you can test for it.

if (sender != null && sender.Equals(buttonStart))
{
   // work with this information
}

However, if you find yourself going down this route, you may end up seeing multiple if blocks each with different behaviors depending on the identity of sender. If that is the case, you’d be better served with a different approach. Have a different handler for each event, encapsulate the differing logic via a delegate, etc. Do not end up with a page full of if / else if / else if / ....
