stringBuild里面的XML文件，转化为DataSet

现有

    /**//// <summary>
        /// 生成BLCM02报文
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void GetMessage_BLCM02()
        {
            str_BLCM02=new StringBuilder();
            str_BLCM02.Append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
            str_BLCM02.Append("<Message><Message_Head>");
            str_BLCM02.Append("<Message_Type>BLCG01</Message_Type>");
            str_BLCM02.Append("<Message_ID>0000010000022006021418000000</Message_ID>");
            str_BLCM02.Append("<Sender_ID>000001</Sender_ID>");
            str_BLCM02.Append("<Receiver_ID>000002</Receiver_ID>");
            str_BLCM02.Append("<Sender_IP>192.168.0.1</Sender_IP><Receiver_IP>192.168.0.2</Receiver_IP><Sender_Port>3333</Sender_Port><Receiver_Port>3334</Receiver_Port><Send_Date>20060214</Send_Date><Send_Time>18000000</Send_Time><Version>001</Version><Message_Ref>0000010000022006021418000000</Message_Ref><Pic_Type>0</Pic_Type><Notes>备注</Notes>");
            str_BLCM02.Append("</Message_Head>");
            str_BLCM02.Append("<Message_Body><Exception_Traffic_Info><Err_No>200602140001</Err_No><IO_No>IO20060214180000</IO_No><Entr_No>0002</Entr_No><Entr_Name>社会车辆入场通道</Entr_Name><IC_Num>012345678</IC_Num><Ve_Num>苏E12345</Ve_Num><Entr_Pic> </Entr_Pic><Ve_Pic> </Ve_Pic><IO_Time>20060214T18000000</IO_Time><Exception>权限校验不通过</Exception></Exception_Traffic_Info></Message_Body>");
            str_BLCM02.Append("</Message>");
        }

其中定义了

 StringBuilder str_BLCM02;//通行异常信息（车辆）

把string 转化为DataSet如下：

    private void Show_Message()
        {
            DataSet ds=new DataSet();
            try
            {
                string str=str_BLCM02.ToString();                
                System.IO.StringReader reader = new System.IO.StringReader(str);
                ds.ReadXml(reader);  
                DataTable dt1=ds.Tables["Message_Head"];
                DataTable dt2=ds.Tables["Exception_Traffic_Info"];
                //根据通道编号决定显示位置
                string str_channel1=System.Configuration.ConfigurationSettings.AppSettings["channel1"];
                string str_channel2=System.Configuration.ConfigurationSettings.AppSettings["channel2"];
                if (str_channel1==dt2.Rows[0]["Entr_No"].ToString())
                {
                    FillDataToFrm(0,dt2);
                }
                if (str_channel2==dt2.Rows[0]["Entr_No"].ToString())
                {
                    FillDataToFrm(1,dt2);
                }
            }
            catch
            {

            }
            
        }
