Question

I’m having a few problems with Regular Expressions in VB.NET.

I have a String like this one: "[Type=User][User=Hello]Thats the message"

I want to have the "Thats the message" part, so I thought that the best way to do that was replacing "[Type=User][User=Hello]" for "".

Notes:

• "Thats the message" is always at the end of the String and it can be "" (without characters).

• [Type=XXXX] can be anything, I mean, it can be [Type=Password], [Type=Message]…

So, here is what I did:

Dim regOptions As RegexOptions = RegexOptions.IgnoreCase Or RegexOptions.Singleline
Regex.Replace(buffer, "^(.*)[^\]]*$", "", regOptions)

It doesn’t work, the string ‘buffer’ is not modified.

Answer 1

According to the documentation of that overload it will return the resulting string (after all, in .Net strings are immutable).

So, instead, try:

buffer = Regex.Replace(buffer, "^(.*)[^\]]*$", "", regOptions)
