public static T WriteJson(this System.Data.DataSet dataSet)
{
    try
    {
        XmlDocument doc = new XmlDocument();
        doc.LoadXml(dataSet.GetXml());
        return (T)Convert.ChangeType(JsonConvert.SerializeXmlNode(doc).Replace("null", "\"\"").Replace("'", "\'"), typeof(T));
    }
    catch (Exception ex)
    {
        throw ex;
    }
}
