本文介绍了一个使用C#与VelocityEngine结合的例子，演示了如何创建用户信息列表，并通过模板引擎渲染这些数据到HTML页面的过程。文章包含了初始化VelocityEngine、设置模板路径、填充数据上下文以及渲染HTML输出的具体实现。

protected void Page_Load(object sender, EventArgs e)
    {
        IList<UserInfo> listUsers = new List<UserInfo>();

        UserInfo objUser = new UserInfo();
        objUser.Name = "TestUser1";
        objUser.Sex = "M";
        objUser.City = "ShenZhen";
        listUsers.Add(objUser);

        objUser = new UserInfo();
        objUser.Name = "TestUser2";

        VelocityEngine engine = new VelocityEngine();
        ExtendedProperties props = new ExtendedProperties();
        props.AddProperty("file.resource.loader.path", Server.MapPath("."));
        engine.Init(props);
        Template template = engine.GetTemplate("HTMLPage2.htm");

        VelocityContext context = new VelocityContext();
        context.Put("name", "VelocityEngine测试</br>");//修改模版页中的
        context.Put("listUsers", listUsers);

        tool tool = new tool();//新类
        context.Put("nono", tool);

        System.Text.StringBuilder builder = new System.Text.StringBuilder();
        builder.Append("#foreach($u in $listUsers)\r\n" +
            "#beforeall\r\n" +

        System.IO.StringWriter vltWriter = new System.IO.StringWriter();
        template.Merge(context, vltWriter);
        engine.Evaluate(context, vltWriter, null, builder.ToString());

       // System.IO.StringWriter vltWriter = new System.IO.StringWriter();

        Response.Write(vltWriter.GetStringBuilder().ToString());
