HttpWebRequest.GetResponse给内部服务器错误

Question

我想使用Http-Post方法向Web服务发出请求。这是我在C＃中的代码。

 static void Main(string[] args) 
     { 
      var _url = "http://localhost/EventWebService/EventWebService.asmx"; 
      var _action = "http://localhost/EventWebService/EventWebService.asmx?op=GetPerson"; 

      XmlDocument soapEnvelope = new XmlDocument(); 
      soapEnvelope.LoadXml(@"<SOAP-ENV:Envelope xmlns:SOAP-ENV=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:xsi=""http://www.w3.org/1999/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/1999/XMLSchema""><SOAP-ENV:Body><GetPerson xmlns=""http://tempuri.org/"" SOAP-ENV:encodingStyle=""http://schemas.xmlsoap.org/soap/encoding/""><name>Brad</name><surname>Pitt</surname><age>51</age></GetPerson></SOAP-ENV:Body></SOAP-ENV:Envelope>"); 

      HttpWebRequest request = (HttpWebRequest)WebRequest.Create(_url); 
      request.Headers.Add("SOAPAction", _action); 
      request.ContentType = "text/xml;charset=\"utf-8\""; 
      request.Accept = "text/xml"; 
      request.Method = "POST"; 
      InsertSoapEnvelopeIntoWebRequest(soapEnvelope, request); 
      WebResponse response = request.GetResponse(); 
      StreamReader rd = new StreamReader(response.GetResponseStream()); 
      Console.WriteLine(rd.ReadToEnd()); 
     } 

     private static void InsertSoapEnvelopeIntoWebRequest(XmlDocument soapEnvelopeXml, HttpWebRequest webRequest) 
     { 
      using (Stream stream = webRequest.GetRequestStream()) 
      { 
       soapEnvelopeXml.Save(stream); 
      } 
     } 

这里是我的Web服务方法和使用的一类：

[WebMethod] 
    [ return: XmlElement("ReturnValueElement",IsNullable=false)] 
    public Person GetPerson([XmlElement("Name")] string name, [XmlElement("Surname")] string surname, [XmlElement("Age")] int age) 
    { 
     return new Person(name, surname, age); 
    } 

    public class Person 
    { 
     string Name { get; set; } 
     string Surname { get; set; } 
     int Age { get; set; } 

     public Person() { } 

     public Person(string _name, string _surname, int _age) 
     { 
      Name = _name; 
      Surname = _surname; 
      Age = _age; 
     } 
    }; 

这里是我的配置文件配置Web服务：

<configuration> 
    <system.web> 
    <webServices> 
     <protocols> 
      <add name="HttpSoap"/>    
      <add name="Documentation"/> 
      <add name="HttpPostLocalhost"/> 
      <add name="HttpPost"/> 
     </protocols> 
    </webServices> 
    <compilation debug="true" targetFramework="4.5" /> 
    <httpRuntime targetFramework="4.5" /> 
    </system.web> 
</configuration> 

在主，当我调试WebResponse response = request.GetResponse();行，我得到与协议错误状态的内部服务器错误（500）。

任何想法？谢谢你们。

使用此代码try和catch方法

try 
{ 
    // Your Code 
} 

catch(Exception wex) 
{ 
    string pageContent = new StreamReader(wex.Response.GetResponseStream()).ReadToEnd().ToString(); 
    return pageContent; 
}
