c# - 使用 C# 帮助发送 SOAP 消息需要

Question

我想向 Web 服务发送 SOAP 消息并读取响应。我的代码如下: 感谢您的帮助。

我希望我的问题不再重复，我四处寻找解决方案，但没有成功。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Services;
using System.Xml;
using System.Net;
using System.IO;

namespace TolunaPush
{
    public partial class _Default : System.Web.UI.Page
    {
        private string sourceID = "50001255";
        private string email = "adsvine@gmail.com";
        private string firstName = "Muz";
        private string lastName = "Khan";
        private string countryID = "2000077";
        private string countryLanguage = "2000240";
        private string postalCode = "N19 3NU";
        private string dob = "1977-03-08";
        private string gender = "2000247";

        protected void Page_Load(object sender, EventArgs e)
        {
            sendSoapMessage();
        }

        protected void sendSoapMessage()
        {
            XmlDocument doc = new XmlDocument();
            doc.InnerXml = @"<soap:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
                  <soap:Body>
                    <SubmitPanelist xmlns=""http://www.greenfield.com/RegistrationGateway/Messages"">
                      <Registration xmlns=""http://www.greenfield.com/RegistrationGateway/Types"">
                        <Source>
                          <SourceID>" + sourceID + @"</SourceID>
                        </Source>
                        <Email>" + email + @"</Email>
                        <FirstName>" + firstName + @"</FirstName>
                        <LastName>" + lastName + @"</LastName>
                        <CountryUK>
                          <CountryID>" + countryID + @"</CountryID>
                          <Language>" + countryLanguage + @"</Language>
                          <Address>
                            <Postalcode>" + postalCode + @"</Postalcode>
                          </Address>
                        </CountryUK>
                        <DOB>" + dob + @"</DOB>
                        <Gender>" + gender + @"</Gender>
                      </Registration>
                    </SubmitPanelist>
                  </soap:Body>
                </soap:Envelope>";

            HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://coreg.surveycenter.com/RegistrationGateway/PanelistService.asmx");
            //if (proxy != null) req.Proxy = new WebProxy(proxy, true);
            // req.Headers.Add("GetClientInfo", "http://tempuri.org/GetClientInfo");

            req.ContentType = "text/xml;charset=\"utf-8\"";
            req.Accept = "text/xml";
            req.Method = "POST";

            Stream stm = req.GetRequestStream();
            doc.Save(stm);
            stm.Close();
            WebResponse resp = req.GetResponse();

            stm = resp.GetResponseStream();
            StreamReader r = new StreamReader(stm);
            Response.Write(r.ReadToEnd());
            //Response.Write(stm.ToString());
            //Response.Write(r.ToString());
            Response.End();
        }
    }
}

更新正如达林所建议的那样。我按照指示做了但是下面的代码行

using (var client = new RegistrationBindingsClient("RegistrationBindings"))

给出错误

The type or namespace name 'RegistrationBindingsClient' could not be found (are you missing a using directive or an assembly reference?)

任何帮助将不胜感激

您尝试使用的 Web 服务在 following address 处提供了一个 WSDL。 .因此，只需右键单击解决方案资源管理器中的引用并使用 Visual Studio 中的“添加服务引用”对话框并指向 WSDL，它将生成强类型类以便您轻松使用服务，就像这样:

protected void sendSoapMessage()
{
    using (var client = new RegistrationBindingsClient("RegistrationBindings"))
    {
        var registration = new RegistrationType();
        registration.Source = new SourceType();
        registration.Source.SourceID = "50001255";
        registration.Email = "adsvine@gmail.com";
        registration.FirstName = "Muz";
        registration.LastName = "Khan";
        var countryUK = new CountryTypeUK();
        countryUK.CountryID = 2000077;
        countryUK.Language = 2000240;
        countryUK.Address = new AddressTypeUK();
        countryUK.Address.Postalcode = "N19 3NU";
        registration.Item = countryUK;
        registration.DOB = new DateTime(1977, 3, 8);
        registration.Gender = 2000247;

        client.SubmitPanelist(registration);
    }
}

看看它是多么容易。您不必担心任何 SOAP 和 XML 管道。

如果您对使用此请求在线发送的实际底层 SOAP 信封感兴趣:
