Jscript.net可以用JScript 或任意NET 框架语言(如 C #,VB7.0) 通过增加extends主题词在类声明以后来继承和扩展现有类。这能力允许Jscript.net非常容易地利用 NET 平台的丰厚资源。为了说明这些,给出一个程序。这个程序扩展了NET 框架的ServiceBase 类。
// 导入需要的.net命名空间
import System;
import System.ServicePRocess;
import System.Diagnostics;

{
private var timer : Timer;
function SimpleService()
{
CanPauseAndContinue = true;
ServiceName = "JScript Service";
timer = new Timer();
timer.Interval = 1000;
timer.AddOnTimer(OnTimer);
}
protected override function OnStart(args : String[])
