Answer 4

You should add namespace if you are not using it:

System.Windows.Forms.MessageBox.Show("Some text", "Some title", 
    System.Windows.Forms.MessageBoxButtons.OK, 
    System.Windows.Forms.MessageBoxIcon.Error);

Alternatively, you can add at the begining of your file:

using System.Windows.Forms

and then use (as stated in previous answers):

MessageBox.Show("Some text", "Some title", 
    MessageBoxButtons.OK, MessageBoxIcon.Error);

        DialogResult result = MessageBox.Show("Are you sure you want to exit?", 
        "", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Question);
        if (result == DialogResult.Yes)
        {
            Application.Exit();
        }
