Windows Phone-使用Java Web服务

Question

I'm a beginner in C#, my Visual Studio is the 2010, my version of Windows Phone 7 is researched on the internet and in this version of the command "async" only works Visual Studio 12 up.

You have any other alternative?

I can map the webservice with references service, but the return is always zero, but in Android works, what the error might be?

I changed the code to stay as he told me, but the error continues to occur: Unmarshalling Error: unexpected element (uri: "webservices.com.br/"; site: "parameter1"). The expected elements are <{} parameter2>, <{} parameter1> The following source code:

public partial class MainPage : PhoneApplicationPage{
  wsServico.cadastroTo cadastroTo = null; 

  public MainPage(){
    InitializeComponent();
  }

  private void button1_Click(object sender, RoutedEventArgs e){
    wsServico.TesteJavaWsClient ws = new wsServico.TesteJavaWsClient();
    ws.returnServicoAsync("A", "B");         
    ws.returnServicoCompleted += new EventHandler<wsServico.returnServicoCompletedEventArgs>(ws_returnServicoCompleted);

  }

  void ws_returnServicoCompleted(object sender, wsServico.returnServicoCompletedEventArgs e){
    cadastroTo = e.Result;
    textBox1.Text = cadastroTo.cadastroId.ToString();        

  }

}

Answer 1

You are setting your textbox too early - before the web service call returns. After you fire off the web service call, you are immediately setting your textbox, which will be empty. You want to set the value in the ws_returnServicoCompleted method, after the web service has returned results.

private void button1_Click(object sender, RoutedEventArgs e){
    wsServico.TesteJavaWsClient ws = new wsServico.TesteJavaWsClient();
    ws.returnServicoAsync("A", "B");         
    ws.returnServicoCompleted += new EventHandler<wsServico.returnServicoCompletedEventArgs>(ws_returnServicoCompleted);
}

void ws_returnServicoCompleted(object sender,
   wsServico.returnServicoCompletedEventArgs e){
       cadastroTo = e.Result;
       cadastroTo.cadastroId.ToString();
}
