如何在使用WriteElementString时避免XML注入

我有以下代码并抛出XML注入(请参阅高亮显示的文本)。可以有人让我知道如何可以删除

private string GetRecordSet(OleDbDataReader oDR)
        {
            XmlTextWriter xTWriter = null;
            StringWriter oSWriter = null;
            int iRecCnt=0;
            string sName = String.Empty;
            string sValue = String.Empty;
            try
            {
                //Create Out XML    
                oSWriter = new StringWriter();
                xTWriter = new XmlTextWriter(oSWriter);
                xTWriter.Formatting = Formatting.Indented;
                xTWriter.WriteStartElement("SESSION");
                while(oDR.Read()) 
                {
                    iRecCnt++;
                    sName = oDR.GetValue(0).ToString();
                    sValue = oDR.GetValue(1).ToString();
                    **xTWriter.WriteElementString(sName, sValue);**
                }
                xTWriter.WriteElementString("TotalRecords", iRecCnt.ToString());
                xTWriter.WriteEndElement(); //ROWSET END
                //Return XML string. If no records found then return empty string
                string sRtrn = oSWriter.ToString();
                if (iRecCnt == 0) sRtrn = string.Empty;
                return sRtrn;
            }
