C＃遍历MapLocationFinderResult

Question

我在尝试从MapLocationFinderResult列表中获取多个项目时感到困惑。 我尝试过使用foreach循环：

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();
        }

错误是：

严重性代码描述项目文件行抑制状态 错误CS1503参数1：无法转换为＆＃39; Windows.Services.Maps.MapLocation＆＃39;到＆＃39; int＆＃39; MapsApp C：\ Users \ Robert \ OneDrive \ VSProjects \ MapsApp \ MapsApp \ MainPage.xaml.cs 72有效

我应该尝试投射吗？

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

Answer 1

i的类型为MapLocation，但您尝试将其用作索引。试试这段代码：

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