我已经编写了以下代码，但它给出了错误:

找不到类型或名称空间IAPEntities.

Hi All,

I have written the following code but it gives the error:

the type or namespace IAPEntities could not be found.

protected void btngenerate_Click(object sender, EventArgs e)
        {
            ReportDocument report = new ReportDocument();
            report.Load(Server.MapPath("CrystalReport1.rpt"));

            using (IAPEntities db = new IAPEntities())
            {
                report.SetDataSource(from u in db.attendance1 select new { u.type, u.present, u.absent, u.working, u.month});
            }

            CrystalReportViewer1.ReportSource = report;
        }
