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）：

 

 

 

 

 

 

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 });          }      }  }
