I must to use .NET 2.0 and I have no Linq support here, also...

I've tried to trim chars using Remove() and Trim() functions like:

  string guid = Guid.NewGuid().ToString();
  string result = header.Trim( new Char[] { ' ', '-'} ));

But for the Trim() sample, the result is the same as string guid ( they are just equal ).

I've done such function, but I want to use correctly functions from the sealed String class.

        string guid = Guid.NewGuid().ToString(); 
        string result = String.Empty;

        for (int i = 0; i < guid.Length; i++)
        {
            if (guid[i] != '-') result += guid[i];
        }

But it looks like plain C style and I want to use exactly String function. Where did I fail with Trim() and Remove().

Don't forget, that I can't use Linq or higher version of .net 2.0, so the question is on the lower level...

string guid = Guid.NewGuid().ToString("N"); //generate it the right way

or

result = guid.Replace("-", "").Replace(" ", "");

Don't use a Regex. It is unnecessarily complex and unnecessarily slow. It is not the best solution.

you could always use regex 

 system.text.regularexpressions.regex.replace(guid.NewGuid(),"[\s|-]","");

  • @OlegOrlov no problem, it's often difficult to understand a person's true intentions over the internet. My comment was directed at the answerer, not you. – Mike G Jan 12 '13 at 22:54
