XElement生成XML的问题

qufusongyu 2011-06-28 05:45:55



   DataTable dt = dsPurchaseInfo.Tables[0];

            //int rows = dt.Rows.Count;

            int rows = 1;

            XElement rtnXml = new XElement("PURCHASE");

            for (int i = 0; i < rows; i++)

            {

                DataRow row = dt.Rows[i];

                XElement tmpjl = new XElement("PURCHASE_INFO",

                     new XElement("HOSPITAL_CODE", row["HOSPITAL_CODE"].ToString().Trim()),

                     new XElement("PRODUCT_ID", row["PRODUCT_ID"].ToString().Trim()),

                     new XElement("REQUEST_QTY", row["REQUEST_QTY"].ToString().Trim()),

                     new XElement("SALE_ORG_CODE", row["SALE_ORG_CODE"].ToString().Trim())

                     );

                rtnXml.Add(tmpjl);

            }

            string PurchaseXml = rtnXml.ToString();

            textBox2.Text = PurchaseXml;

textbox2.text显示的内容为:

<PURCHASE>
<PURCHASE_INFO>
<HOSPITAL_CODE>370000737997</HOSPITAL_CODE>
<PRODUCT_ID>9370100000000</PRODUCT_ID>
<REQUEST_QTY>10000.00</REQUEST_QTY>
<SALE_ORG_CODE>37464</SALE_ORG_CODE>
</PURCHASE_INFO>
</PURCHASE>

但是问题出来了.
对方webservice接收到解密后,服务出错.
经过跟踪,找到问题,
跟踪为:
textbox2.text

"<PURCHASE>\r\n <PURCHASE_INFO>\r\n <HOSPITAL_CODE>370000737997</HOSPITAL_CODE>\r\n <PRODUCT_ID>9370100000000</PRODUCT_ID>\r\n <REQUEST_QTY>10000.00</REQUEST_QTY>\r\n <SALE_ORG_CODE>37464</SALE_ORG_CODE>\r\n </PURCHASE_INFO>\r\n</PURCHASE>"

中间发现有\r\n 字符,这个原因可能导致的问题,因为我用静态值形成以上格式,对方服务解析是可以的.正确
如何避免呢?

C# code

StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);
rtnXml.Save(sw, SaveOptions.DisableFormatting);
string xml = sb.ToString();

用字符串拼接或者格式化字符串。

StringBuilder sb = new StringBuilder();

StringWriter sw = new StringWriter(sb);

rtnXml.Save(sw, SaveOptions.DisableFormatting);

string xml = sb.ToString();
