NVelocity中调用方法 一定要通过 类.方法

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);


        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 "   +
             " <table border=\ " 0 \ "  cellpadding=\ " 10 \ "  cellspacing=\ " 10 \ " > "   +
             " <tr><td>Name</td><td>Sex</td><td>City</td></tr> "   +

             " #end " );


        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());

    }
