Android：如何将 XML 文件传递​​给 .net WebService 并在 Web Service 中处理 XML 文件？

Question

我想使用以下代码创建一个 Xml 文件并将其传递给 .net Web 服务。但是，我不知道如何在 .net Web 服务中获取和处理这个 XML 文件。你能帮我解决这个问题吗？

public void registration(String[] data) {       

 String line = "<UserData
                Name=\"Username" Email = \"emaiAddress" Password = \"Password" +
                "SecurityQuestion = \"Question" SAnswer = \"SAnswer"/>";

 try {

  DefaultHttpClient httpClient = new DefaultHttpClient();

  HttpPost httpPost = new HttpPost(localhost + "UserData");

      StringEntity se = new StringEntity(line, HTTP.UTF_8);

      se.setContentType("text/xml");

  httpPost.setEntity(se);

  HttpResponse httpResponse = httpClient.execute(httpPost);
  HttpEntity httpEntity = httpResponse.getEntity();             

      line = EntityUtils.toString(httpEntity);

  } catch (UnsupportedEncodingException e) {            

  }
}

我可以知道如何从 Web 服务中的这个 xml 获取属性。我尝试使用以下代码。但是卡住了，不知道如何进行。

//user registration

[WebMethod]
public void registration(XmlDocument data)
{
     XmlDocument xml = data;
     var username = xml.GetElementsByTagName("Username");            



}

提前感谢您的帮助。

试试这个。，

public void registration(String[] data) {       

     String line = "<UserData
                    Name=\"Username" Email = \"emaiAddress" Password = \"Password" +
                    "SecurityQuestion = \"Question" SAnswer = \"SAnswer"/>";

     try {

      DefaultHttpClient httpClient = new DefaultHttpClient();

      HttpPost httpPost = new HttpPost(localhost + "UserData");

          StringEntity se = new StringEntity(line, HTTP.UTF_8);

          se.setContentType("text/xml");

      httpPost.setEntity(se);

      HttpResponse httpResponse = httpClient.execute(httpPost);
      HttpEntity httpEntity = httpResponse.getEntity();     

      if (httpResponse != null) {       
                    InputStream in = httpResponse.getEntity().getContent();
                    DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
                    Document doc = builder.parse(in);

                    if (doc != null) {

                        NodeList Username_node = doc.getElementsByTagName("Username");
                        String usrname = Username_node.item(0).getChildNodes().item(0).getNodeValue();
                        System.out.println(""+usrname);
                    }
                } else {
                    showAlert(thisActivity, "No response");
                }

      } catch (UnsupportedEncodingException e) {            

      }
      }
