如何在mapcontrol控件上显示多个地点标注

TsanyLee。

对于你提到的问题，我创建了一个示例工程去测试，以下是我的代码：

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，在模拟器上，MapIcon有时候可以显示，但是缩放后，有些又可以正常显示，对于这个问题，我尝试通过强制自定义MapIcon的Image属性，但是没有解决。

通过定位问题，觉得可能的问题是在于模拟器，于是在真机上发现均可以正常显示这些点，所以建议你在真机上测试程序的效果。
