首先在html文件下写入下面代码；
<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <style type="text/css"> body, html, #allmap { width: 100%; height: 100%; overflow: hidden; margin: 0; font-family: 微软雅黑; } </style> <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=您的密钥"></script> //<script type="text/javascript" src="MarkerClusterer_min.js"></script> //<script type="text/javascript" src="LuShu_min.js"></script> <title>获取地图经纬度</title> </head> <body> <div id="mouselng" style="visibility:hidden"></div> <div id="mouselat" style="visibility:hidden"></div> <div id="allmap"></div> </body> </html> <script type="text/javascript"> var map = new BMap.Map("allmap"); var point = new BMap.Point(116.404, 39.915); map.centerAndZoom(point, 8);//窗体加载之后初始的坐标点和放缩倍数 map.enableScrollWheelZoom(true); //开启鼠标滚轮缩放 //map.centerAndZoom(); map.enableKeyboard(true);//开启键盘控制 map.addEventListener("mousemove", GetlngAndlat);//添加鼠标移动获取经纬度功能 //获取坐标 function GetlngAndlat(e) { if (e.point.lng != null) { document.getElementById("mouselng").innerHTML = e.point.lng; document.getElementById("mouselat").innerHTML = e.point.lat; } } </script>添加一个 timer控件，然后在cs文件中的窗体启动方法中写入下面函数：
#region 窗体加载事件 private void F_HistoricalTraceControl_Load(object sender, EventArgs e) { string str_url = Application.StartupPath + "定义的HTML文件名称.html";//放在debug文件夹下 Uri url = new Uri(str_url); HistoricalTraceWebBrowser.Url = url; HistoricalTraceWebBrowser.ObjectForScripting = this; latLngTimer.Enabled = true;//timer控件 } #endregion添加一个timer事件，代码如下：
#region 鼠标移动获取地图上点的经纬度 private void latLngTimer_Tick(object sender, EventArgs e) { try { //将html中获取的坐标交互 string tag_lng = HistoricalTraceWebBrowser.Document.GetElementById("mouselng").InnerText; string tag_lat = HistoricalTraceWebBrowser.Document.GetElementById("mouselat").InnerText; double dou_lng, dou_lat; if (double.TryParse(tag_lng, out dou_lng) && double.TryParse(tag_lat, out dou_lat)) { //显示当前点位置，根据自己的要求将经纬度显示出来 sSecItem.Caption = string.Format("经度：{0}, 纬度：{1} ", dou_lng.ToString("F5"), dou_lat.ToString("F5")); } } catch (Exception ee) { //MessageBox.Show(ee.Message); } } #endregion
