JAVA to C# code translation request Please

Hi
Could anyone translate this Java code to C# for me. I don't know Java and I can't find suitable methods in C# in order to make this code work.



import java.net.*;
import java.io.*;

/**
 * A sample program that shows how to interact with MapViewer
 */

public class MapViewerDemo {
  private HttpURLConnection mapViewer = null;



  /**
   * Initializes this demo with the URL to the MapViewer server.
   * The URL is typically http://my_corp.com:8888/mapviewer/omserver.
   */
  public MapViewerDemo(String mapViewerURLString) {
    URL url;
    try {
      url = new URL(mapViewerURLString);
      mapViewer = (HttpURLConnection) url.openConnection();
      mapViewer.setDoOutput(true);
      mapViewer.setDoInput(true);
      mapViewer.setUseCaches(false);
    }
    catch (Exception e) {
      e.printStackTrace(System.err);
      System.exit(1);
    }
  }

  /**
   * Submits an XML request to MapViewer.
   Map Request Examples
   3-12 Oracle Application Server MapViewer User’s Guide
   * @param xmlreq the XML document that is a MapViewer request
   */
  public void submitRequest(String xmlreq) {
    try {
      mapViewer.setRequestMethod("POST"); //Use HTTP POST method.
      OutputStream os = mapViewer.getOutputStream();
//MapViewer expects to find the request as a parameter
//named "xml_request".
      xmlreq = "xml_request=" + URLEncoder.encode(xmlreq);
      os.write(xmlreq.getBytes());
      os.flush();
      os.close();
    }
    catch (Exception e) {
      e.printStackTrace(System.err);
      System.exit(1);
    }
  }

  /**
   * Receives an XML response from MapViewer.
   */
  public String getResponse() {
    ByteArrayOutputStream content = new ByteArrayOutputStream();
    InputStream is = null;
    try {
      is = mapViewer.getInputStream();
      int c;
      while ( (c = is.read()) != -1) {
        content.write(c);
      }
      is.close();
      content.flush();
      content.close();
      return content.toString();
    }
    catch (Exception e) {
      e.printStackTrace(System.err);
      return null;
    }
  }

// A simple main program that sends a list_data_sources XML
// request to MapViewer through HTTP POST
 


}



Thanks
