C＃迭代MapLocationFinderResult

Question

我很難試圖從MapLocationFinderResult列表中獲取多個項目。 我使用foreach循環嘗試：

private async void GetRouteAndDirections() 
    { 
     // Query hint 
     queryHint = new BasicGeoposition(); 
     queryHint.Latitude = -37.8136; 
     queryHint.Longitude = 144.9631; 
     Geopoint hintPoint = new Geopoint(queryHint); 

     // Start 
     //BasicGeoposition startLocation = new BasicGeoposition(); 
     result = await MapLocationFinder.FindLocationsAsync(addressToGeocode, hintPoint, 10); 

     // End 

     // Get route 

     // Show 
     if (result.Status == MapLocationFinderStatus.Success) 
     { 
      foreach (MapLocation i in result.Locations) 
      { 
       txtMessage.Text += (result.Locations[i].Address.Street + " \n"); // need to figure out how to iterate over this 
      } 

      AddMapIcon(); 
     } 

的錯誤是：

嚴重性代碼說明項目文件的線路抑制狀態 錯誤CS1503參數1：無法從「Windows.Services.Maps轉換.MapLocation」到 '廉政' MapsApp C：\用戶\羅伯特\ OneDrive \ VSProjects \ MapsApp \ MapsApp \ MainPage.xaml.cs中72活動

我應該試圖投它，不知何故？

這是使用Windows.Services.Maps; Windows.Devices.Geolocation; Windows.UI.Xaml.Controls.Maps

Answer 1

i類型爲MapLocation，但您試圖將其用作索引。試試這個代碼：

foreach (MapLocation i in result.Locations) 
{ 
    txtMessage.Text += (i.Address.Street + " \n"); 
}
