TsanyLee。

對于你提到的問題，我創建了一個示例工程去測試，以下是我的代碼：

MainPage.xaml:

private void Button_Click(object sender, RoutedEventArgs e)

{

AddMapIcon();

}

private void AddMapIcon()

{

MapIcon MapIcon1 = new MapIcon();

MapIcon
1.Location = new Geopoint(new BasicGeoposition()

{

Latitude = 4
7.620,

Longitude = -12
2.349

});

MapIcon
1.NormalizedAnchorPoint = new Point(0.5,
1.0);

MapIcon
1.Title = "Space Needle";

MapIcon
1.Visible = true;

MapIcon
1.ZIndex = int.MaxValue;

MapControl
1.MapElements.Add(MapIcon1);

MapIcon MapIcon2 = new MapIcon();

MapIcon
2.Location = new Geopoint(new BasicGeoposition()

{

Latitude = 4
7.603569,

Longitude = -12
2.329453

});

MapIcon
2.NormalizedAnchorPoint = new Point(0.5,
1.0);

MapIcon
2.Title = "Seattle";

MapIcon
2.Visible = true;

MapIcon
2.ZIndex = int.MaxValue;

MapControl
1.MapElements.Add(MapIcon2);

MapControl
1.Center = MapIcon
1.Location;

MapControl
1.ZoomLevel = 12;

}

如你所提到的，在模擬器上，MapIcon有時候可以顯示，但是縮放后，有些又可以正常顯示，對于這個問題，我嘗試通過強制自定義MapIcon的Image屬性，但是沒有解決。

通過定位問題，覺得可能的問題是在于模擬器，于是在真機上發現均可以正常顯示這些點，所以建議你在真機上測試程序的效果。
