本文通过一个具体的示例展示了如何使用Velocity模板引擎将数据填充到HTML模板中，并生成动态网页内容。示例中创建了一个用户信息列表，并利用Velocity进行渲染。

Code
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";
        objUser.Sex = "F";
        objUser.City = "BeiJing";
        listUsers.Add(objUser);

        objUser = new UserInfo();
        objUser.Name = "TestUser3";
        objUser.Sex = "M";
        objUser.City = "USA";
        listUsers.Add(objUser);

        System.Text.StringBuilder builder = new System.Text.StringBuilder();
        builder.Append("#foreach($u in $ListUsers)\r\n" +
            "#beforeall\r\nssssssssssssssssssssssssssssssss" +
            "<table border=\"0\" cellpadding=\"10\" cellspacing=\"10\">" +
            "<tr><td>Name</td><td>Sex</td><td>City</td></tr>" +
            "#each\r\n" +
            "<tr>" +
            "<td>" + nono("$u.Name")+ "</td>" +   ////////调用处
            "<td>$u.Sex</td>" +
            "<td>$u.City</td>" +
            "</tr>" +
            "#afterall\r\n" +
            "</table>" +
            "#nodata\r\n" +
            "暂无用户资料\r\n" +
            "#end");

        VelocityEngine vltEngine = new VelocityEngine();
        vltEngine.Init();

        VelocityContext vltContext = new VelocityContext();
        vltContext.Put("PageTitle", "字符串模板例子");
        vltContext.Put("ListUsers", listUsers);

        System.IO.StringWriter vltWriter = new System.IO.StringWriter();
        vltEngine.Evaluate(vltContext, vltWriter, null, builder.ToString());

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

    //方法名
    public string nono(string dd)
    {
        return dd;
    }
