// 百度地圖API功能
var map = new BMap.Map("allmap");
map.centerAndZoom("重慶",12); //初始化地圖,設定城市和地圖層級。
var pointA = new BMap.Point(106.486654,29.490295); // 建立點座標A--大渡口區
var pointB = new BMap.Point(106.581515,29.615467); // 建立點座標B--江北區
alert(‘從大渡口區到江北區的距離是：‘+(map.getDistance(pointA,pointB)).toFixed(2)+‘ 米。‘); //擷取兩點距離,保留小數點後兩位
var polyline = new BMap.Polyline([pointA,pointB], {strokeColor:"blue", strokeWeight:6, strokeOpacity:0.5}); //定義折線
map.addOverlay(polyline); //添加折線到地圖上
function getdistance() //這個是自己添加的，自己定義個方法然後讓WINFORM調用，（當然也可以反過來，WINFORM中定義個方法，JS中再調用）
{return map.getDistance(pointA,pointB).toFixed(2);}

加入控制項WEBBROWER
在表單load中加入代碼
string str_url = Application.StartupPath + "\\HTM的名字.htm"; //htm要放到DEBUG目錄下 ，如果不用啟動目錄放任意目錄 string str_url="";自己琢磨吧 Uri url = new Uri(str_url); webBroGIS.Url = url; webBroGIS.ObjectForScripting = this;上WINform代碼
var s = webBrowser1.Document.InvokeScript("getdistance");//引號中是function的函數名，注意變數要用var型
txtbox.text=s.tostring();

幾個問題 1亂碼要把charset 改成gb2312,2秘鑰自己網上搜吧
