所以我试图做的是基本上调用谷歌地图webservice发送我的经度和纬度,我会得到我的位置的详细信息。例如街道名称和地址。

代码最初工作,直到它开始提供“远程服务器返回错误:NotFound”的错误消息。

所以试图解决这个问题我做了另一个简单的事情,其唯一的功能是发送谷歌地图API请求如下

MainPage.xaml,它只包含一个文本块和一个按钮。该按钮将简单地发送请求,结果将打印在文本块中。所以我想不需要在这里展示

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Navigation;
using Microsoft.Phone.Controls;
using Microsoft.Phone.Shell;
using GetStreetName.Resources;

namespace GetStreetName
{
     public partial class MainPage : PhoneApplicationPage
     {
    // Constructor
    public MainPage()
    {
        InitializeComponent();

        // Sample code to localize the ApplicationBar
        //BuildLocalizedApplicationBar();
    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        WebClient webClient = new WebClient();
        webClient.DownloadStringCompleted += new DownloadStringCompletedEventHandler(getStreet_DownloadStringCompleted);
        webClient.Headers["Accept"] = "application/json";

        webClient.DownloadStringAsync(new Uri("https://maps.googleapis.com/maps/api/geocode/json?latlng=51.480837,-0.190243&sensor=true"));

    }

    private void getStreet_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
    {
        if (e.Cancelled == true)
        {
            streetLabel.Text = "Download cancelled.";
            return;
        }

        if (e.Error != null)
        {
            streetLabel.Text = e.Error.Message;
            return;
        }

        MessageBox.Show(e.Result);
        streetLabel.Text = e.Result;

    }

    // Sample code for building a localized ApplicationBar
    //private void BuildLocalizedApplicationBar()
    //{
    //    // Set the page's ApplicationBar to a new instance of ApplicationBar.
    //    ApplicationBar = new ApplicationBar();

    //    // Create a new button and set the text value to the localized string from AppResources.
    //    ApplicationBarIconButton appBarButton = new ApplicationBarIconButton(new Uri("/Assets/AppBar/appbar.add.rest.png", UriKind.Relative));
    //    appBarButton.Text = AppResources.AppBarButtonText;
    //    ApplicationBar.Buttons.Add(appBarButton);

    //    // Create a new menu item with the localized string from AppResources.
    //    ApplicationBarMenuItem appBarMenuItem = new ApplicationBarMenuItem(AppResources.AppBarMenuItemText);
    //    ApplicationBar.MenuItems.Add(appBarMenuItem);
    //}
 }
}

经度和纬度只是通向切尔西足球俱乐部球场的虚拟价值。 无论如何,如果您尝试在某种REST控制台中使用相同的URL,它将完全正常工作。

有什么建议吗?提前致谢
