How do I create a message box with “Yes”, “No” choices and a DialogResult?

Question

I want to make simple Yes/No choiced MessageBox, but I think it is nonsense to design a form for that. I thought I could use MessageBox, add buttons, etc. to accomplish this

Answer 1

DialogResult dr = MessageBox.Show("Are you happy now?", 
                      "Mood Test", MessageBoxButtons.YesNo);
switch(dr)
{
   case DialogResult.Yes:
      break;
   case DialogResult.No:
      break;
}

MessageBox class is what you are looking for.
