You could do the same thing with a regular expression:if (Regex.Replace(textBox1.Text, @D, ) == textBox1.Text){textBox2.Text = (tryparse method succeed);} else { textBox2.Text=(value entered is not numeric); }

You could do the same thing with a regular expression:

if (Regex.Replace(textBox1.Text, @"\D", "") == textBox1.Text)
{
textBox2.Text = ("tryparse method succeed");
} else { textBox2.Text=("value entered is not numeric"); }
