C#-Soap如何从响应中获取值

标签 c# xml soap response

我正在开发 C# 控制台应用程序。我硬编码了一个 soap 请求，我在其中传递了 200 个唯一 ID，如下所示。

请求

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++;
                    }
                }
            }
        }
    }
}

上面的代码只给我第一个 ID 的值。如何获取所有 ID 的所有值？

更新 1

根据 jdweng解决方案。我已经尝试过了，并且一切正常。响应中有很多值，所以我不想要所有的值。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下面列出的值

 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;
    }

如您所见，我的第一个代码中已经调用了此函数 kwhRead1 = GetRead(ds, ReadTypeEnum.KWH1); .我也想这样做。

如有任何帮助，我们将不胜感激。

使用 xml linq。下面的代码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，应该将结果字符串化为 xml
