     dtMessageInfo.TableName = "MSGInfoName";
     MemoryStream streamSaveUldByte = new MemoryStream();
     dtMessageInfo.WriteXml(streamSaveUldByte, XmlWriteMode.WriteSchema);
     LogMsgByte = streamSaveUldByte.ToArray();

     //将数组转换为datatable
     MemoryStream stream = new MemoryStream(LogMsgByte);
     dtMessageInfo.ReadXml(stream);
