    Filtering a string?

    ok, i've been trying to make an application that:

    1. user selects a text file through a open file dialog
    2. content of text file is displayed in a textbox
    3. user clicks a button with the caption "filter"
    4. then the program will filter out everything apart from links

    i've got up to step 3 but i can't seem to figure out how to filter everything apart from rapidshare links from the text box, any help is appreciated, thanks in advanced.

    Regards, Look-

    Use regular expressions:
    string Input = "Yatta yolla yorka yinto";
    string Expression = "http://www\\.rapidshare\\.com.*? ";
    System.Text.RegularExpressions.Regex Regex = new System.Text.RegularExpressions.Regex(Expression);
    foreach(System.Text.RegularExpressions.Match Match in Regex.Matches(Input))
    	string FullAddress = Input.Substring(Match.Index, Match.Length);
    The above code is relatively simple, may be improved. Like it assumes the address ends with a blankspace.
