MessageBox Buttons?

Question

How would I say if the yes button on the messagebox was pressed do this,that and the other? In C#.

Answer 1

1. Your call to MessageBox.Show needs to pass MessageBoxButtons.YesNo to get the Yes/No buttons instead of the OK button.

2. Compare the result of that call (which will block execution until the dialog returns) to DialogResult.Yes....

if (MessageBox.Show("Are you sure?", "Confirm", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes) {     // user clicked yes } else {     // user clicked no } 

Answer 2

If you actually want Yes and No buttons (and assuming WinForms):

void button_Click(object sender, EventArgs e) {     var message = "Yes or No?";     var title = "Hey!";     var result = MessageBox.Show(         message,                  // the message to show         title,                    // the title for the dialog box         MessageBoxButtons.YesNo,  // show two buttons: Yes and No         MessageBoxIcon.Question); // show a question mark icon      // the following can be handled as if/else statements as well     switch (result)     {     case DialogResult.Yes:   // Yes button pressed         MessageBox.Show("You pressed Yes!");         break;     case DialogResult.No:    // No button pressed         MessageBox.Show("You pressed No!");         break;     default:                 // Neither Yes nor No pressed (just in case)         MessageBox.Show("What did you press?");         break;     } }
