example (note: label1 and label2 can have only numbers):

If is label1.Text = 5  and label2.Text = 6

how to make a comparison, something like:

if (label1.Text < label2.Text)
{
   MessageBox.Show("some text...",
                    this.Text, MessageBoxButtons.OK, MessageBoxIcon.Information);
                return;
}
