java to c# correction.

hi, i am converting j2me to c# .net compact framework. however after the convertion, i cant seem to make the connection done. it seems like some logic may be wrong. i need help. thanks. below are the java and c# codes.

J2ME

import java.io.*;
import javax.microedition.io.*;

public class HttpConnectionHelper {
String mSession;
public interface Callback {
void prepareRequest( String originalURL,
HttpConnection conn ) throws IOException;
}
public static HttpConnection connect( String url ) throws IOException {
return connect( url, null );
}

public static HttpConnection connect( String url, Callback callback )
throws IOException {

HttpConnection conn1 = null;
String originalURL = url;

while( url != null ){
conn1 = (HttpConnection)
Connector.open( url );

if( callback != null ){
callback.prepareRequest( originalURL, conn1 );
}

int rc = conn1.getResponseCode();

switch( rc ){
case HttpConnection.HTTP_MOVED_PERM:
case HttpConnection.HTTP_MOVED_TEMP:
case HttpConnection.HTTP_SEE_OTHER:
case HttpConnection.HTTP_TEMP_REDIRECT:
url = conn1.getHeaderField( "Location" );
if( url != null && url.startsWith( "/*" ) ){
StringBuffer b = new StringBuffer();
b.append( "http://" );
b.append( conn1.getHost() );
b.append( ':' );
b.append( conn1.getPort() );
b.append( url );
url = b.toString();
}
conn1.close();
break;
default:
url = null;
break;
}
}
return conn1;
}
}
