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.

Answer 2

Use:

MessageBoxResult m = MessageBox.Show("The file will be saved here.", "File Save", MessageBoxButton.OKCancel);
if(m == m.Yes)
{
    // Do something
}
else if (m == m.No)
{
    // Do something else
}

MessageBoxResult is used on Windows Phone instead of DialogResult...

Answer 3

dynamic MsgResult = this.ShowMessageBox("Do you want to cancel all pending changes ?", "Cancel Changes", MessageBoxOption.YesNo);

if (MsgResult == System.Windows.MessageBoxResult.Yes)
{
    enter code here
}
else 
{
    enter code here
}

Answer 4

MessageBox.Show(title, text, messageboxbuttons.yes/no)

This returns a DialogResult which you can check.

For example,

if(MessageBox.Show("","",MessageBoxButtons.YesNo) == DialogResult.Yes)
{
   //do something
}

Answer 5

@Mikael Svenson's answer is correct. I just wanted to add a small addition to it:

The Messagebox icon can also be included has an additional property like below:

DialogResult dialogResult = MessageBox.Show("Sure", "Please Confirm Your Action", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
