對谷歌地圖操作使用的是WebBrowser控件，通過對javascript的操作來實現(xiàn)對谷歌地圖的各種操作，所以首先要創(chuàng)建一個html文件，并賦給WebBrowser的URl：
<!DOCTYPE html> <html> <head> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <meta http-equiv="content-type" content="text/html; charset=UTF-8"/> <title>Google Maps</title> <link href="http://code.google.com/apis/maps/documentation/javascript/examples/default.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var map; function initialize() {//初始化 var myLatlng = new google.maps.LatLng( 34.259442,108.947071); var myOptions = { zoom: 10, center: myLatlng, mapTypeId: google.maps.MapTypeId.ROADMAP } map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); } function zoomIn(){//放大函數(shù) var zoomLevel = map.getZoom(); if(zoomLevel < 21){ zoomLevel += 1; map.setZoom(zoomLevel); } } function zoomOut(){//縮小函數(shù) var zoomLevel = map.getZoom(); if(zoomLevel > 0){ zoomLevel -= 1; map.setZoom(zoomLevel); } } function markLocation(x,y){//標記某個位置 var myLatlng = new google.maps.LatLng(x, y); map.setCenter(myLatlng); marker = new google.maps.Marker({ map: map, position: myLatlng, draggable:true, title:"緯度:"+x+" 經(jīng)度:"+y }); } </script> </head> <body onload="initialize()"> <div id="map_canvas"></div> </body> </html> 操作地圖的簡單函數(shù)都寫在javascript里
C#源文件如下
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; namespace GoogleMapDemo { public partial class Form1 : Form { public Form1() { InitializeComponent(); string url = Application.StartupPath + "/map-simple.html"; webBrowser1.Url = new Uri(url);//指定url } private void toolStripButtonStart_Click(object sender, EventArgs e) { webBrowser1.Document.InvokeScript("initialize");//執(zhí)行jiavascript } private void toolStripButtonZoomIn_Click(object sender, EventArgs e) { webBrowser1.Document.InvokeScript("zoomIn"); } private void toolStripButtonZoomOut_Click(object sender, EventArgs e) { webBrowser1.Document.InvokeScript("zoomOut"); } private void toolStripButtonMark_Click(object sender, EventArgs e) { object[] obj = { toolStripTextBox1.Text, toolStripTextBox2.Text }; webBrowser1.Document.InvokeScript("markLocation", obj); } } }
PS：如果只是想單純地調(diào)用瀏覽器打開網(wǎng)頁，可以這樣：
private void lbllink_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e) { //調(diào)用IE瀏覽器 System.Diagnostics.Process.Start("iexplore.exe", "http://www.google.cn"); //調(diào)用系統(tǒng)默認的瀏覽器 System.Diagnostics.Process.Start( "http://www.google.cn"); } private void lbllink_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e) { //調(diào)用IE瀏覽器 System.Diagnostics.Process.Start("iexplore.exe", "http://www.google.cn"); //調(diào)用系統(tǒng)默認的瀏覽器 System.Diagnostics.Process.Start( "http://www.google.cn"); }
