string manipulation

[Kiran A K]

hi,

can anybody give me a c# method that removes non-alphanumeric characters
from a string?
i would prefer it if the code uses regular expressions.

HI

Hope this could help you

public static void Main()

{


/*Reg expression to find non-alphanumeric characters*/

string pattern = @"[^A-Za-z0-9]";

/*include System.Text.RegularExpressions name space*/

Regex rgx = new Regex(pattern);

string inputStr = "ab$!Cd&%$gf£!";

/*Replace non-alphanumeric characters with space*/

string outputStr = rgx.Replace(inputStr, " ");


Console.WriteLine("Output string:"+ outputStr);

}

Sting numbers = Regex.Replace(inputString, "[^\d]", String.Empty);

Whoops. I misread the question. You asked about "non-alphanumeric
characters." That would be:

String numbers = Regex.Replace(inputString, "[^\w]", String.Empty);
