ArcGIS_Runtime_SDK for.Net 鼠标移动获取坐标前端代码

以下是使用 ArcGIS Runtime SDK for .Net 获取鼠标移动坐标的前端代码示例：

private void MyMapView_MouseMove(object sender, MouseEventArgs e)
{
    // 获取鼠标所在的屏幕坐标
    System.Windows.Point screenPoint = e.GetPosition(MyMapView);

    // 将屏幕坐标转换为地图坐标
    MapPoint mapPoint = MyMapView.ScreenToLocation(screenPoint);

    // 显示地图坐标信息
    txtMapPoint.Text = string.Format("X:{0:F4} Y:{1:F4}", mapPoint.X, mapPoint.Y);
}

上述代码中，`MyMapView` 是 ArcGIS Runtime SDK for .Net 中的地图控件，当鼠标移动时，会触发 `MyMapView_MouseMove` 事件。在该事件中，首先获取鼠标所在的屏幕坐标，然后将屏幕坐标转换为地图坐标，最后将地图坐标信息显示在界面上。

ArcGIS_Runtime_SDK for.Net 鼠标移动获取坐标MainPage代码

以下是使用 ArcGIS_Runtime_SDK for .Net 的 MainPage 代码，其中包括鼠标移动获取坐标的功能：

using Esri.ArcGISRuntime.Geometry;
using Esri.ArcGISRuntime.Mapping;
using Esri.ArcGISRuntime.UI;
using System;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;

namespace MapApp
{
    public sealed partial class MainPage : Page
    {
        private MapView _mapView;

        public MainPage()
        {
            this.InitializeComponent();

            Initialize();
        }

        private async void Initialize()
        {
            // Create a new Map with the basemap of your choice
            Map myMap = new Map(Basemap.CreateImageryWithLabels());

            // Set the initial viewpoint
            Envelope initialLocation = new Envelope(
                -123.085428, 49.199165, -122.883469, 49.326968,
                SpatialReferences.Wgs84);
            myMap.InitialViewpoint = new Viewpoint(initialLocation);

            // Create the MapView control
            _mapView = new MapView
            {
                Map = myMap
            };

            // Add the MapView to the page
            MyMapView.Content = _mapView;

            // Listen for mouse movement events
            _mapView.MouseMove += MapView_MouseMove;
        }

        private async void MapView_MouseMove(object sender, Esri.ArcGISRuntime.UI.Controls.MapViewInputEventArgs e)
        {
            // Get the coordinates of the mouse pointer
            MapPoint geoPoint = (MapPoint)GeometryEngine.Project(e.Location, SpatialReferences.Wgs84);

            // Display the coordinates in a TextBlock
            CoordinatesTextBlock.Text = $"Latitude: {geoPoint.Y:F4}, Longitude: {geoPoint.X:F4}";
        }
    }
}

在此代码中，我们首先创建了一个 MapView 控件，并将其添加到页面中。然后，我们启用了鼠标移动事件处理程序 MapView_MouseMove。在该事件处理程序中，我们使用 GeometryEngine.Project 方法将屏幕坐标转换为地理坐标，并将其显示在 TextBlock 中。
