How do I replace the *first instance* of a string in .NET?

Question

I want to replace the first occurrence in a given string.

How can I accomplish this in .NET?

Answer 1

And because there is also VB.NET to consider, I would like to offer up:

Private Function ReplaceFirst(ByVal text As String, ByVal search As String, ByVal replace As String) As String
    Dim pos As Integer = text.IndexOf(search)
    If pos >= 0 Then
        Return text.Substring(0, pos) + replace + text.Substring(pos + search.Length)
    End If
    Return text 
End Function
