VB .net - shortest and fastest way to find Nth occurrence of char in string?

Question

What is the professional way to achieve this?

Thanks.

I've shamelessly ripped off the example from this question and converted it from C# to VB.net.

Public Function GetNthIndex(s As String, t As Char, n As Integer) As Integer
    Dim count As Integer = 0
    For i As Integer = 0 To s.Length - 1
        If s(i) = t Then
            count += 1
            If count = n Then
                Return i
            End If
        End If
    Next
    Return -1
End Function
