对谷歌地图操作使用的是WebBrowser控件，通过对javascript的操作来实现对谷歌地图的各种操作，所以首先要创建一个html文件，并赋给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测试数据/apis/maps/documentation/javascript/examples/default.css" rel= "stylesheet" type= "text/css" />
<script type= "text/javascript" src= "http://maps.google测试数据/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(){ //放大函数
var zoomLevel = map.getZoom();
if (zoomLevel < 21){
zoomLevel += 1;
map.setZoom(zoomLevel);
}
}
function zoomOut(){ //缩小函数
var zoomLevel = map.getZoom();
if (zoomLevel > 0){
zoomLevel -= 1;
map.setZoom(zoomLevel);
}
}
function markLocation(x,y){ //标记某个位置
var myLatlng = new google.maps.LatLng(x, y);
map.setCenter(myLatlng);
marker = new google.maps.Marker({
map: map,
position: myLatlng,
draggable: true ,
title: "纬度:" +x+ " 经度:" +y
});
}
</script>
</head>
<body onload= "initialize()" >
<div id= "map_canvas" ></div>
</body>
</html>
操作地图的简单函数都写在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" ); //执行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：如果只是想单纯地调用浏览器打开网页，可以这样：
private void lbllink_LinkClicked( object sender, LinkLabelLinkClickedEventArgs e)
{
//调用IE浏览器
System.Diagnostics.Process.Start( "iexplore.exe" , "http://HdhCmsTestgoogle.cn" );
//调用系统默认的浏览器
System.Diagnostics.Process.Start( "http://HdhCmsTestgoogle.cn" );
}
private void lbllink_LinkClicked( object sender, LinkLabelLinkClickedEventArgs e)
{
//调用IE浏览器
System.Diagnostics.Process.Start( "iexplore.exe" , "http://HdhCmsTestgoogle.cn" );
//调用系统默认的浏览器
System.Diagnostics.Process.Start( "http://HdhCmsTestgoogle.cn" );
}
dy("nrwz");
