篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了C＃ - 如何从响应中获取值相关的知识，希望对你有一定的参考价值。
我正在开发一个C＃控制台应用程序。我已经硬编码了一个soap请求，其中我已经传递了200个唯一ID，如下所示。

通过它后，我能够得到一个值的响应

获取响应和值的代码
using (WebResponse webResponse = webRequest.EndGetResponse(asyncResult))
{
using (StreamReader rd = new StreamReader(webResponse.GetResponseStream()))
{
soapResult = rd.ReadToEnd();
var result = XmlDecode(soapResult);
XDocument doc = XDocument.Parse(result);
XmlReader read = doc.CreateReader();
DataSet ds = new DataSet();
ds.ReadXml(read);
read.Close();
if (ds.Tables.Count > 0 && ds.Tables["Reply"] != null && ds.Tables["Reply"].Rows.Count > 0)
{
kwhRead1 = GetRead(ds, ReadTypeEnum.KWH1);
kvhRead1 = GetRead(ds, ReadTypeEnum.KVH1);
mdiRead1 = GetRead(ds, ReadTypeEnum.MDI1);
kwhRead2 = GetRead(ds, ReadTypeEnum.KWH2);
kvhRead2 = GetRead(ds, ReadTypeEnum.KVH2);
mdiRead2 = GetRead(ds, ReadTypeEnum.MDI2);
string ts = GetTSpan(ds, ReadTypeEnum.KWH1).Replace("T", " ");
timeSpan = ts.Remove(ts.Length-6);
if (ds.Tables["Reply"].Rows[0][0].ToString().ToUpper() == "OK")
{
if (ds.Tables["Names"] != null && ds.Tables["Names"].Rows.Count > 0)
{
uniqueKey = ds.Tables["Names"].Rows[0]["name"].ToString();
}
if (ds.Tables["NameType"] != null && ds.Tables["NameType"].Rows.Count > 0)
{
refNo = ds.Tables["NameType"].Rows[0]["name"].ToString();
}
if (ds.Tables["Meter"] != null && ds.Tables["Meter"].Rows.Count > 0)
{
if (ds.Tables["Meter"].Columns.Contains("mRID"))
{
meterNo = ds.Tables["Meter"].Rows[0]["mRID"].ToString();
processedRec++;
}
}
}
}
}
}
上面的代码只给出了第一个ID的值。我怎样才能获得所有ID的所有值？
更新1
根据jdweng解决方案。我试过了，我把事情搞定了。响应中有很多值，所以我不想要所有这些值。我只想要有用的数据。换句话说，有很多ReadingType，但我想得到一些具体的ReadingType值列出如下
const string _readTypeKWH1 = "13.26.0.1.1.1.12.0.0.0.0.1.0.0.224.3.72.0";
const string _readTypeKWH2 = "13.26.0.1.1.1.12.0.0.0.0.2.0.0.224.3.72.0";
const string _readTypeKVH1 = "13.26.0.1.1.1.12.0.0.0.0.1.0.0.224.3.73.0";
const string _readTypeKVH2 = "13.26.0.1.1.1.12.0.0.0.0.2.0.0.224.3.73.0";
const string _readTypeMDI1 = "13.8.0.6.1.1.8.0.0.0.0.1.0.0.224.3.38.0";
const string _readTypeMDI2 = "13.8.0.6.1.1.8.0.0.0.0.2.0.0.224.3.38.0";
private enum ReadTypeEnum
{
KWH1,
KVH1,
MDI1,
KWH2,
KVH2,
MDI2,
}
以前，对于单个响应，我使用的是一个函数。
private static double GetRead(DataSet ds, ReadTypeEnum type, int i)
{
double TotRead = 0;
int ReadID = 0;
string readType = "";
try
{
if (ds.Tables.Count > 0)
{
if (ds.Tables["ReadingType"] != null && ds.Tables["ReadingType"].Rows.Count > 0)
{
switch (type)
{
case ReadTypeEnum.KWH1:
readType = _readTypeKWH1;
break;
case ReadTypeEnum.KVH1:
readType = _readTypeKVH1;
break;
case ReadTypeEnum.MDI1:
readType = _readTypeMDI1;
break;
case ReadTypeEnum.KWH2:
readType = _readTypeKWH2;
break;
case ReadTypeEnum.KVH2:
readType = _readTypeKVH2;
break;
case ReadTypeEnum.MDI2:
readType = _readTypeMDI2;
break;
default:
readType = _readTypeKWH1;
break;
}
DataRow[] dr = ds.Tables["ReadingType"].Select("ref='" + readType + "'");
if (dr != null && dr.Length > 0)
{
ReadID = int.Parse(dr[i]["Readings_Id"].ToString());
}
}
if (ReadID != 0 && ds.Tables["Readings"] != null && ds.Tables["Readings"].Rows.Count > 0)
{
DataRow[] drRead = ds.Tables["Readings"].Select("Readings_Id='" + ReadID.ToString() + "'");
if (drRead != null && drRead.Length > 0 && drRead[0]["value"] != null && !drRead[0]["value"].ToString().Equals("null"))
TotRead = double.Parse(drRead[0]["value"].ToString());
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
return TotRead;
}
正如你所看到的，我的第一个代码kwhRead1 = GetRead(ds, ReadTypeEnum.KWH1);已经调用了这个函数。我也想这样做。
任何帮助将受到高度赞赏。
答案
使用xml linq。下面的代码是从文件中读取并将结果放入字符串xml中。您的代码正在读取响应，并且应该将字符串结果写入xml
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.IO;
namespace ConsoleApplication110
{
class Program
{
const string FILENAME = @"c: emp est.xml";
static void Main(string[] args)
{
string xml = File.ReadAllText(FILENAME);
XDocument doc = XDocument.Parse(xml);
XElement root = doc.Root;
XNamespace mNs = root.GetNamespaceOfPrefix("m");
List<XElement> xMeterReadings = doc.Descendants(mNs + "MeterReading").ToList();
List<MeterReadings> meterReadings = new List<MeterReadings>();
foreach (XElement xMeterReading in xMeterReadings)
{
MeterReadings newMeterReading = new MeterReadings();
meterReadings.Add(newMeterReading);
XElement valuesInterval = xMeterReading.Element(mNs + "valuesInterval");
newMeterReading.start = (DateTime)valuesInterval.Element(mNs + "start");
newMeterReading.end = (DateTime)valuesInterval.Element(mNs + "end");
XElement meter = xMeterReading.Element(mNs + "Meter");
newMeterReading.name = (string)meter.Descendants(mNs + "name").FirstOrDefault();
newMeterReading.nameType = (string)meter.Descendants(mNs + "name").LastOrDefault();
newMeterReading.mRid = (string)meter.Element(mNs + "mRID");
List<XElement> xReadings = xMeterReading.Elements(mNs + "Readings").ToList();
foreach (XElement xReading in xReadings)
{
string readingType = (string)xReading.Element(mNs + "ReadingType").Attribute("ref");
ReadTypeEnum typeEnum = MeterReading.GetType(readingType);
if (typeEnum != ReadTypeEnum.NONE)
{

MeterReading meterReading = new MeterReading();
newMeterReading.meterReadings.Add(meterReading);
meterReading.readingType = readingType;
meterReading.start = (DateTime)valuesInterval.Descendants(mNs + "start").FirstOrDefault();
meterReading.end = (DateTime)valuesInterval.Descendants(mNs + "end").FirstOrDefault();
meterReading.value = (decimal)xReading.Element(mNs + "value");
