1、首先用一个html文件调用百度地图接口（主要注册一个序列号）：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>百度地图的Hello World</title>
<style type="text/css">
body, html, #allmap
{
width: 100%;
height: 100%;
overflow: hidden;
margin: 0;
}
#l-map
{
height: 100%;
width: 78%;
float: left;
border-right: 2px solid #bcbcbc;
}
#r-result
{
height: 100%;
width: 20%;
float: left;
}
</style>
<script type="text/javascript" src="http://api.map.baidu.com/api?v=1.5&ak=6c497f51c06477544e5fa6e9bd68f7c3"></script>
</head>
<body>
<div id="allmap">
</div>
</body>
</html>
<script type="text/javascript">
//alert("Hello World");
var map = new BMap.Map("allmap"); // 创建Map实例
var point = new BMap.Point(121.504, 31.212); // 创建点坐标(经度,纬度)
map.centerAndZoom(point, 11); // 初始化地图,设置中心点坐标和地图大小级别
map.addOverlay(new BMap.Marker(point)); // 给该坐标加一个红点标记
//var traffic = new BMap.TrafficLayer(); // 创建交通流量图层实例
//map.addTileLayer(traffic); // 将图层添加到地图上
map.addControl(new BMap.NavigationControl()); // 添加平移缩放控件
map.addControl(new BMap.ScaleControl()); // 添加比例尺控件
map.addControl(new BMap.OverviewMapControl()); //添加缩略地图控件
map.addControl(new BMap.MapTypeControl()); //添加地图类型控件
map.setCurrentCity("上海"); //设置地图显示的城市
map.enableScrollWheelZoom(); //启用滚轮放大缩小
function setLocation(x,y){//参数：经纬度
var point = new BMap.Point(x, y);
map.centerAndZoom(point, 11);
map.addOverlay(new BMap.Marker(point));
}
</script>
2、建立一个Winform项目，用一个WebBrower控件查看html文件、调用JavaScript代码
using System;
using System.IO;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace BaiDuMap
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
try
{
//webBrowser1.Url = new Uri("http://www.2345.com");
//这个文件于可执行文件放在同一目录
webBrowser1.Url = new Uri(Path.Combine(Application.StartupPath, "GoogleMap.htm"));
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "异常", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
//这里传入x、y的值，调用JavaScript脚本
webBrowser1.Document.InvokeScript("setLocation", new object[] { 121.504, 39.212 });
}
}
}
