Automatically remove Subversion unversioned files

Question

Does anybody know a way to recursively remove all files in a working copy that are not under version control? (I need this to get more reliable results in my automatic build

C# code snipet above did not work for me - I have tortoise svn client, and lines are formatted slightly differently. Here is same code snipet as above, only rewritten to function and using regex.

        /// 

    /// Cleans up svn folder by removing non committed files and folders.
    /// 
    void CleanSvnFolder( string folder )
    {
        Directory.SetCurrentDirectory(folder);

        var psi = new ProcessStartInfo("svn.exe", "status --non-interactive");
        psi.UseShellExecute = false;
        psi.RedirectStandardOutput = true;
        psi.WorkingDirectory = folder;
        psi.CreateNoWindow = true;

        using (var process = Process.Start(psi))
        {
            string line = process.StandardOutput.ReadLine();
            while (line != null)
            {
                var m = Regex.Match(line, "\\? +(.*)");

                if( m.Groups.Count >= 2 )
                {
                    string relativePath = m.Groups[1].ToString();

                    string path = Path.Combine(folder, relativePath);
                    if (Directory.Exists(path))
                    {
                        Directory.Delete(path, true);
                    }
                    else if (File.Exists(path))
                    {
                        File.Delete(path);
                    }
                }
                line = process.StandardOutput.ReadLine();
            }
        }
    } //CleanSvnFolder
