Does the first "name1" occur in the same place?

If not, you could use an IF statement to test if the string exists.  If it does exist, then do the replace using the substr function, then EXIT the IF statement.

See String.Replace method...
    Dim s As String = "some text, name1, some more text, name1"
    s = s.Replace("name1", "name2")

Are you trying to replace just the first occurance or all occurances of "name1"?

Replacing only the first occurrence could be done with:
Dim s As String = "some text, name1, some more text, name1"

        Dim find As String = "name1"
        Dim replaceWith As String = "name2"
        Dim index As Integer = s.IndexOf(find)
        If index <> -1 Then
            s = s.Remove(index, find.Length)
            s = s.Insert(index, replaceWith)
        End If

Try this:
Dim oldStr As String = "some string name1 new string name1 test"
Dim newStr As String = Replace(oldStr, "name1", "name2", , 1)
