Removing first occurrence of string within a string?

Hi everyone

I'm wondering how i could remove the first occurrence of a set of characters from a string, and then looping until there are no characters left in the string.

For example:
I want to remove the first "wer" from "qwertyqwertyqwerty", so that the string then reads "qtyqwertyqwerty".

Any ideas on how to do that?

EDIT: Clarified example.

string.replace()

Code:

---

Dim str As String = "qwerty"
        Console.WriteLine(str.Replace("wer", ""))
        Console.ReadLine()

---

generally when you have a question about string manipulation the first place to look is msdn.

vb.net Code:

Dim testString As String = "Chumbawumba"
        MsgBox(Replace(testString, "umb", "", 1, 1)) 'source, search string, replacement, start, number of repetitions

Sorry, I meant if the substring you want to remove occurs more than once in a string. Like removing the first "wer" from "qwertyqwertyqwerty".

Yes, I know. That's what my code does. If you'd tried it you would know that it changes Chumbawumba to Chawumba.
