如何在vs2012中連接到ASMX Web服務

Question

我目前正在開發中。 我正在嘗試在Windows Store項目中連接Web服務。

在這段代碼中沒有錯誤，但是沒有任何反應。 我要使用其他代碼還是在Web服務的調用結果中放置一些消息框？

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Windows.Foundation;
using Windows.Foundation.Collections;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Controls.Primitives;
using Windows.UI.Xaml.Data;
using Windows.UI.Xaml.Input;
using Windows.UI.Xaml.Media;
using Windows.UI.Xaml.Navigation;

namespace Windows8App
{

public sealed partial class Login : Page
{  
    public Login()
    {
        this.InitializeComponent();
    }

    protected override void OnNavigatedTo(NavigationEventArgs e)
    {
    }

    private async void loginAsync(string username, string password)
    {
          ServiceReference1.Service1SoapClient service = new ServiceReference1.Service1SoapClient();
          var response = service.loginwebAsync(username, password);
    }

    private void btnLogin_Click(object sender, RoutedEventArgs e)
    {
          string user = txtUsername.Text;
          string pass = txtPassword.Text;

          System.Threading.Tasks.Task.Run(() =>
          {
              loginAsync(user, pass);
          });
    }
}
}

您的服務呼叫缺少await關鍵字。 像這樣重新編寫代碼。 如果有效，請將其標記為答案，否則我將刪除答案。

private async Task loginAsync(string username, string password)
{
      ServiceReference1.Service1SoapClient service = new ServiceReference1.Service1SoapClient();
      var response = await service.loginwebAsync(username, password);
}

private async void btnLogin_Click(object sender, RoutedEventArgs e)
{
      string user = txtUsername.Text;
      string pass = txtPassword.Text;

      await loginAsync(user, pass);
}
