从以上答复中我想从上述答复中获取一些数据。以下是我的代码
From above reply I want to get some data from above response. Below is my code
if (dt != null && dt.Rows.Count > 0)
{
totalRec = dt.Rows.Count;
timer.Start();
foreach (DataRow dr in dt.Rows)
{
var _url = "http://111.111.111.1:8090/HES/services/DoCommandRequest";
string uniqueID = dr["Application_No"].ToString();
//string meterNo = dr["METER_SERIAL_NO"].ToString();
XmlDocument soapEnvelopeXml = CreateSoapEnvelope(uniqueID);
HttpWebRequest webRequest = CreateWebRequest(_url);
InsertSoapEnvelopeIntoWebRequest(soapEnvelopeXml, webRequest);
// begin async call to web request.
IAsyncResult asyncResult = webRequest.BeginGetResponse(null, null);
// suspend this thread until call is complete. You might want to
// do something usefull here like update your UI.
asyncResult.AsyncWaitHandle.WaitOne();
// get the response from the completed web request.
string soapResult;
using (WebResponse webResponse = webRequest.EndGetResponse(asyncResult))
{
using (StreamReader rd = new StreamReader(webResponse.GetResponseStream()))
{
soapResult = rd.ReadToEnd();
processedRec++;
}
}
}
timer.Stop();
}
在上面的代码中，响应位于字符串 soapResult中。
In above code the response is in the string soapResult.
为了从响应中获取价值，我尝试执行以下操作
For getting a value from the response I tried to do the following
XDocument doc = XDocument.Parse(soapResult);
XmlReader xr = doc.CreateReader();
xr.ReadToFollowing("UserID");
string uid = xr.ReadElementContentAsString();
但是我得到了错误
{节点类型无不支持ReadElementContentAsString方法。第0行，位置0。}
{"The ReadElementContentAsString method is not supported on node type None. Line 0, position 0."}
我也试过了
var result = from p in doc.Descendants()
where p.Name.LocalName == "UserID" select p.Value;
但是我没有结果。
任何帮助将不胜感激
推荐答案
首先获取< return>的值元素转换为一个字符串变量（比如说 string returnValue ）
First Get the value of the <return> element into one string variable (lets say string returnValue)
然后XML解码 returnValue 通过将值传递给以下函数来使用。
Then XML decode the returnValue using by passing the value into the following function.
public static string XmlDecode(string value) {
var xmlDoc = new XmlDocument();
xmlDoc.LoadXml("<root>" + value + "</root>");
return xmlDoc.InnerText;
}
上述函数返回的值是有效的XML，您可以使用 XDocument.Parse 或LINQ to XML
The returned value from above function is valid XML that you can parse using the XDocument.Parse or LINQ to XML
