XElement生成XML的有关问题

XElement生成XML的问题

C# code

   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?

[解决办法]

C# code

StringBuilder sb = new StringBuilder();StringWriter sw = new StringWriter(sb);rtnXml.Save(sw, SaveOptions.DisableFormatting);string xml = sb.ToString();
[解决办法]
用字符串拼接或者格式化字符串。

探讨

C# code

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

[解决办法]
\\r\\n
