首先，在Google地图上订阅一个免费的API序列号Key（登陆http://code.google.com/apis/maps/signup.html，然后把你的域名根目录和TCP/IP端口提交上去）。于是，使用测试工程的时候，别忘了改这些。

我们的GStaticMap控件时继承于System.Web.UI.Image的。
你需要添加的一些属性如下：
The next step is to more deeply describe our objects. So, a static map is defined by the following properties:

    * A width (integer, inherited from Image)宽
    * A height (integer, inherited from Image)高
    * A center (using our GCoordinate class, optional when there is at least one marker)中心位置
    * A zoom level (integer, optional when there is at least one marker, from 1 to 19)缩放尺寸
    * A rendering type (enumerator, optional; roadmap, by default, or designed for mobile devices)地图类型（公路地图还是移动设备等等）

A marker is defined by the following properties:

    * A color (enumerator, optional; the Static Map API restricts them to red, by default, blue, or green)
    * An optional letter (character, optional, from A to Z)

A coordinate is defined by the following properties:

    * A latitude (double)纬度
    * A longitude (double)经度
