Validate NIC field in vb.net

Question

I want to validate NIC number text field in my vb form. It should contain 9 numbers [0-9] and one letter (letter should be "v") (first 9 characters are numbers,last one is a letter)
How do I validate such a thing using regular expression?
Can you help me with the code?
I'm new to this section.

What regex have you tried? – doctorlove Jun 19 '14 at 08:44 — doctorlove, Jun 19 '14 at 08:44

The examples section in the docs shows you.
To match a digit use \d
To match 9 numbers you state you want 9: \d{9}
To match a letter you want [a-zA-Z] (or something more complicated depending on what a letter is). If you specifically want v then just allow v using [v] i.e. \d{9}[v]

Test this with Regex.IsMatch

Try this:

If Not System.Text.RegularExpressions.Regex.IsMatch(TextBox1.Text, "[0-9]{9}v") Then
    MessageBox.Show("Not valid NIC")
End If
