To validate that a textbox contains a string in that format you can use the DateTime.TryParseExact method in combination with Munesh's format string: using System.Globalization; // ... DateTime dt; string format fmt = yyyyMMddHHmmss; CultureInfo ci = CultureInfo.InvariantCulture; DateTimeStyles dts = DateTimeStyles.None; bool isValid = DateTime.TryParseExact(textBox1.Text fmt ci dts out dt); if(!isValid) { MessageBox.Show(Date/Time is not in the correct format. Please amend); textBox1.Focus(); } else { // do something with 'dt' }
