NVelocity对数据的几种绑定

今天体验了一下NVelocity对数据的几种绑定。代码如下

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.IO;
using System.Collections.Generic;

using Commons.Collections;
using NVelocity;
using NVelocity.App;
using NVelocity.Context;
using NVelocity.Runtime;
using System.Data;

public partial class Default2 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        //创建VelocityEngine实例对象
        VelocityEngine velocity = new VelocityEngine();

        //使用设置初始化VelocityEngine
        ExtendedProperties props = new ExtendedProperties();
        props.AddProperty(RuntimeConstants.INPUT_ENCODING, "gb2312");
        props.AddProperty(RuntimeConstants.OUTPUT_ENCODING, "gb2312");
        props.AddProperty(RuntimeConstants.RESOURCE_LOADER, "file");
        props.AddProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, Server.MapPath(@""));
        velocity.Init(props);

        //从文件中读取模板
        Template template = velocity.GetTemplate("for.vm");

        //为模板变量赋值
        IContext context = new VelocityContext();
        context.Put("from", "危超云");
        context.Put("to", "someone");
        context.Put("subject", "Welcome to NVelocity");
        context.Put("name", "John Doe");

        //这个是模板类赋值
        //user ok = new user();
        //ok.Name = "xxx";
        //ok.Id = 222;
        //context.Put("ok", ok);

        //这个是泛型数据
        //IList<user> users = new List<user>();
        //user user1=new user(11,"wei9931");
        //users.Add(user1);
        //user user2 = new user(22, "baidu.com");
        //users.Add(user2);
        //context.Put("arrayList", users);

        //这个是Tabel赋值
        DataTable myDataTable=new DataTable();
        myDataTable.Columns.Add("CustomerID");
        myDataTable.Columns.Add("CompanyName");
        myDataTable.Columns.Add("ContactName");
        myDataTable.Columns.Add("Address");       
        DataRow myNewDataRow = myDataTable.NewRow();      
        myNewDataRow["CustomerID"] = 11;
        myNewDataRow["CompanyName"] = "T1 Company";
        myNewDataRow["ContactName"] = "Jason Price";
        myNewDataRow["Address"] = "1 Main Street";
        myDataTable.Rows.Add(myNewDataRow);
        DataRow myNewDataRow1 = myDataTable.NewRow();
        myNewDataRow1["CustomerID"] = 22;
        myNewDataRow1["CompanyName"] = "T2 Company";
        myNewDataRow1["ContactName"] = "Jason Price";
        myNewDataRow1["Address"] = "1 Main Street";
        myDataTable.Rows.Add(myNewDataRow1);
        IList<user> users = new List<user>();
        for (int i = 0; i < myDataTable.Rows.Count; i++)
        {
            user user1 = new user(Convert.ToInt32(myDataTable.Rows[i]["CustomerID"].ToString()), myDataTable.Rows[i]["CompanyName"].ToString());
            users.Add(user1);
        }
        context.Put("myDataTable", users);

        //这个是数组复值
        //IList arrayList = new ArrayList();
        //arrayList.Add("上海");
        //arrayList.Add("杭州");
        //arrayList.Add("大连");
        //context.Put("arrayList", arrayList);

        //合并模板
        StringWriter writer = new StringWriter();
        template.Merge(context, writer);

        //输出
        Response.Write(writer.ToString().Replace("\r\n", ""));
    }
  
 
}
