c#–获取Windows8桌面应用程序中的位置

我是C#的初学者,但我经常使用Java.我想在我的应用程序中使用以下代码来获取位置数据.我正在制作一个Windows 8桌面应用程序,以便在我的设备中使用GPS传感器：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Windows.Devices.Sensors;
using Windows.Devices.Geolocation;
using Windows.Devices.Geolocation.Geoposition;
using Windows.Foundation;
namespace Hello_Location
{
public partial class Form1 :
{
public Form1()
{
InitializeComponent();
}
async private void Form1_Load(object sender, EventArgs e)
{
Geolocator loc = new Geolocator();
try
{loc.DesiredAccuracy = PositionAccuracy.High;Geoposition pos = await loc.GetGeopositionAsync();var lat = pos.Coordinate.Latitude;var lang = pos.Coordinate.Longitude;Console.WriteLine(lat+ " " +lang);
}
catch (System.UnauthorizedAccessException)
{// handle error
}
}
private void button1_Click(object sender, EventArgs e)
{
}
}
}


我收到此错误：

‘await’ requires that the type

‘Windows.Foundation.IAsyncOperation’

have a suitable GetAwaiter method. Are you missing a using directive

for ‘System’? C:\Users\clidy\documents\visual studio

2012\Projects\Hello-Location\Hello-Location\Form1.cs

我怎样才能解决这个问题？

如果您可以为我指向C#位置的一些资源和Windows桌面应用程序的传感器API,那么它将非常有用.谷歌搜索时,我只获得Windows RT API.

解决方法:

要解决您的错误,您必须参考Bart在其中一个问题评论中提供的link.

You might need to add a reference to System.Runtime.WindowsRuntime.dll

as well if you are using mapped types like Windows Runtime event

handlers:

…

That assembly resides in C:\Program Files (x86)\Reference

Assemblies\Microsoft\Framework.NETCore\v4.5

我最近找到了一个类似问题的“解决方案”：C# desktop application doesn’t share my physical location.也许你可能对我的方法感兴趣：https://stackoverflow.com/a/14645837/674700.

它更像是一种解决方法,并不是针对Windows 8,但它最终会起作用.
