将XML加载到WCF并将信息解析为WCF客户端应用程序

Question

我一直在尝试做的是加载任何XML文件并使用POST和HTTP将其作为参数传递。我遇到的问题是，我无法在客户端获得响应，甚至在本地浏览Service1.svc / XMLTest时也无法获得响应。我的代码如下： service.svc：

using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
using System.IO;
using System.Xml;

namespace XMLService
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.
    public class Service1 :IService1 
    {
        public string XMLTest(Stream XMLParam)
        {  
            XmlDocument xDoc = new XmlDocument();
            xDoc.LoadXml("D:\\test.xml");
            return xDoc.OuterXml;

        }
    }
}

Iservice1.cs

namespace XMLService
{// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
    [ServiceContract]

    public interface IService1
    {
        [OperationContract]
        [WebInvoke(Method = "Post", UriTemplate = "XMLTest")]
        string XMLTest(Stream XMLParam)

    }
}

Web Config

<system.serviceModel>
    <services>
      <!-- Note: the service name must match the configuration name for the service implementation. -->
      <service name="XMLService.Service1" behaviorConfiguration="Default" >
        <endpoint address ="" contract="XMLService.IService1" 
                  binding="webHttpBinding" behaviorConfiguration="web" />
      </service>
    </services>
    <behaviors>
      <endpointBehaviors>
        <behavior name="web">
          <webHttp helpEnabled="true"/>
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="Default">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>

  </system.serviceModel>

客户端Asp.Net页面，我使用“发布”和“HTTP”调用WCF

protected void Button1_Click(object sender, EventArgs e)
        {

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://localhost:23457/Service1.svc/XMLTest");
            request.Method = "POST";  // Set the Method property of the request to POST.

            // Create POST data and convert it to a byte array.
            string postData = "This is a test that posts this string to a Web server.";
            byte[] byteArray = Encoding.UTF8.GetBytes(postData);

            // Set the ContentType property of the WebRequest and Length
            request.ContentType = "application / x - www - form - urlencoded"; //"text/xml";
            request.ContentLength = byteArray.Length;

            //Load the XML Document
            XmlDocument xDoc = new XmlDocument();
            xDoc.LoadXml("D:\\test.xml");
            string rawXml = xDoc.OuterXml;

            // Get the request stream, write the data to the request stream
            Stream dataStream = request.GetRequestStream();
            dataStream.Write(byteArray, 0, byteArray.Length);
            dataStream.Close();

            //Web Response, display the status, 
            WebResponse response = request.GetResponse();
            Console.WriteLine(((HttpWebResponse)response).StatusDescription);

            // Get the stream 
            dataStream = response.GetResponseStream();
            StreamReader reader = new StreamReader(dataStream);

            // Read the content.
            string responseFromServer = reader.ReadToEnd();

            // Display the content.
            Console.WriteLine(responseFromServer);

            // Clean up the streams.
            reader.Close();
            dataStream.Close();
            response.Close(); 

        }
