在我的 asp.net 3.5 a3 层应用程序中使用水晶报告时出现以下错误

命名空间“CrystalDecisions.Web”中不存在类型或命名空间名称“CrystalReportViewer”（您是否缺少程序集引用？）

我包含的命名空间是：

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
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.Xml.Linq;
using MorvelNew.Report;
using System.Data.Sql;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Web;

  1. 右键单击“引用”并选择“添加引用...”
  2. 转到“扩展程序”
  3. 查找“CrystalDecisions.Web”

并添加命名空间。
