對谷歌地圖操作使用的是WebBrowser控件，通過對Javascript的操作來實現對谷歌地圖的各種操作，所以首先要創建一個Html文件，並賦給WebBrowser的URl：
? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55

function initialize() {//初始化
var myLatlng = new google.maps.LatLng( 34.259442,108.947071);
var myOptions = {

function zoomIn(){//放大函數
var zoomLevel = map.getZoom();
if(zoomLevel < 21){
zoomLevel += 1;
map.setZoom(zoomLevel);
}
}
function zoomOut(){//縮小函數
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,

title:"緯度:"+x+" 經度:"+y

操作地圖的簡單函數都寫在Javascript裡
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用浏覽器打開網頁，可以這樣：
private void lbllink_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
//調用IE浏覽器
System.Diagnostics.Process.Start("IExplore.exe", "http://www.google.cn");
//調用系統默認的浏覽器
System.Diagnostics.Process.Start( "http://www.google.cn");
}
private void lbllink_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
//調用IE浏覽器
System.Diagnostics.Process.Start("IExplore.exe", "http://www.google.cn");
//調用系統默認的浏覽器
System.Diagnostics.Process.Start( "http://www.google.cn");
}
