How do you replace the first certain character in a string leaving the second character the same

I just need to know how to replace a the first certain character that appears in a string with a different character.

For example, I need to be able to change "need" to "noed" leaving the second 'e' the same.

What I have right now is changing "need" to "nood"

If you need any clarification please just ask me! Thank you so much!

Use IndexOf() to find the position of the "e". Now Insert() the "o" at that position and Remove() the position immediately following that to remove the "e":

    Dim word As String = "need"
    Dim oldLetter As String = "e"
    Dim newLetter As String = "o"
    Dim index As Integer = word.IndexOf(oldLetter)
    If index <> -1 Then
        word = word.Insert(index, newLetter).Remove(index + 1, 1)
    End If

    Dim findWhat As String = "ee"
    Dim searchThis As String = "need"
    Dim replaceWith As String = "o"
    Dim result As String = searchThis.Replace(findWhat, replaceWith & findWhat.Substring(1))
    Console.WriteLine(result)
