public static string GenerateURL(object Title, object strId)
    {
        string strTitle = Title.ToString();

        #region Generate SEO Friendly URL based on Title
        //Trim Start and End Spaces.
        strTitle = strTitle.Trim();

        //Trim "-" Hyphen
        strTitle = strTitle.Trim('-');

        strTitle = strTitle.ToLower();
        char[] chars = @"$%#@!*?;:~`+=()[]{}|\'<>,/^&"".".ToCharArray();
        strTitle = strTitle.Replace("c#", "C-Sharp");
        strTitle = strTitle.Replace("vb.net", "VB-Net");
        strTitle = strTitle.Replace("asp.net", "Asp-Net");

        //Replace . with - hyphen
        strTitle = strTitle.Replace(".", "-");

        //Replace Special-Characters
        for (int i = 0; i < chars.Length; i++)
        {
            string strChar = chars.GetValue(i).ToString();
            if (strTitle.Contains(strChar))
            {
                strTitle = strTitle.Replace(strChar, string.Empty);
            }
        }

        //Replace all spaces with one "-" hyphen
        strTitle = strTitle.Replace(" ", "-");

        //Replace multiple "-" hyphen with single "-" hyphen.
        strTitle = strTitle.Replace("--", "-");
        strTitle = strTitle.Replace("---", "-");
        strTitle = strTitle.Replace("----", "-");
        strTitle = strTitle.Replace("-----", "-");
        strTitle = strTitle.Replace("----", "-");
        strTitle = strTitle.Replace("---", "-");
        strTitle = strTitle.Replace("--", "-");

        //Run the code again...
        //Trim Start and End Spaces.

        //Trim "-" Hyphen
        strTitle = strTitle.Trim('-');
        #endregion
