在 MVC5 中生成报告时日期未正确绑定？答案

【问题标题】：Date is not binding correctly while generating report in MVC5?在 MVC5 中生成报告时日期未正确绑定？

【问题描述】：

您好，我有一个名为 DailyVisitReport 的视图。它包含 2 个字段，分别称为 FromDate 和 ToDate。我正在生成报告取决于日期。我正在使用 Crystal Report 2010。在正常的本地机器中运行它在 Web 服务器中部署我的应用程序后运行良好，它显示空报告。我会清楚地解释我的问题。

我使用 Web 服务器在线上传我的应用程序。所以我从 Godaddy 购买了虚拟专用服务器。我通过购买的 Web 服务器 IP 地址（来自 Godaddy）使用远程桌面连接在线上传我的应用程序。

在我将应用程序部署到 Web 服务器后生成报告时遇到一个错误之前，该错误如下所述。

所以我问了很多论坛和搜索谷歌。他们中的许多人建议我在 Web 服务器系统的程序集文件夹中添加 CrystalDecistion.ReportAppServer.CommLayer dll，并在 Web.config 文件中引用它。我也这样做了。我再次在 Web 服务器中部署我的应用程序并尝试生成报告。这次它没有显示任何错误，并且还生成了空报告。

问题是日期绑定不正确。我发送给控制器的日期格式是 Fromdate 和 Todate 的 01-mar-16。但是从 db 中检索的日期格式是不同的，例如 08/12/2016 并且它随时间一起提供。我在 db 中保存没有时间的日期。但是在检索时它将带有一个默认时间。

所以我使用

将 sql 中的日期格式转换为字符串格式

Replace(Convert(varchar(50), vf.VisitingDate,6), ' ', '-')As VisitingDate

我还在检索时将 VisitingDate 格式从 String 更改为 date。现在从数据库中检索的日期格式和从日期到日期的格式都是相同的。我普通的本地机器运行得很好。但它在 Web 服务器中部署后显示空报告。有一件事是，如果我没有选择任何日期并单击“确定”按钮，则意味着它会在 Web 服务器的报告中显示所有数据（在表格中）

我的控制器代码

 public ActionResult VisitSummaryReport()
    {
        return View();
    }

    [HttpPost]
    public ActionResult GetDates(VisitorsViewModel VisitorsVM)
    {
        var fromdt = Convert.ToString(string.Format("{0:dd/MMM/yy}", VisitorsVM.FromDate));
        var todt = Convert.ToString(string.Format("{0:dd/MMM/yy}", VisitorsVM.ToDate));
        SqlConnection connection = new SqlConnection(@"Data Source=S192-169-143-12\WAFEEXPRESS;Initial Catalog=CRM;User ID=sa;Password=Wafe@win;");
        //SqlConnection connection = new SqlConnection(@"Data Source=192.168.0.73\SQLEXPRESS,14330;Initial Catalog=CRM;User ID=sa;Password=wafewin;");
        DataTable dt = new DataTable();
        try
        {
            SqlCommand command = new SqlCommand();
            command.Parameters.Add("@fromDate", System.Data.SqlDbType.Date).Value = fromdt;
            command.Parameters.Add("@toDate", System.Data.SqlDbType.Date).Value = todt;
            command.CommandText = "Select * from  [View_VisitorsForm]  Where CAST(VisitingDate AS Date) >= @fromDate and  CAST(VisitingDate AS Date) <= @toDate";


            command.Connection = connection;
            connection.Open();
            SqlDataAdapter adp = new SqlDataAdapter(command);
            adp.Fill(dt);

        }
        catch (Exception ex)
        {
            throw;
        }
        ReportDocument rpt = new ReportDocument();
        rpt.Load(Server.MapPath("~/Areas/Sales/CrystalReports/rpt_VisitSummaryCrystalReport.rpt"));
        rpt.SetDataSource(dt);
        Stream stream = rpt.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
        return File(stream, "application/pdf");
    }

我仍然在 Web 服务器中收到空报告。我尽力解释我的问题。请任何人理解我的问题并帮助我解决这个问题。

提前谢谢。

【问题讨论】：

你必须在你的 web.config 中添加程序集看看你的本地 web.config 应该有程序集你可以将它们添加到你上传的 web.config 中
我更新了我的 web.config 文件。请检查并告诉我想添加哪个参考

标签： c# sql-server date asp.net-mvc-5 crystal-reports

【解决方案1】：

试试这个，将此程序集添加到您的网络配置并检查注意：请更改您使用的版本

如果我没有选择任何日期并单击“确定”按钮，则忘记告诉一件事，这意味着它会在网络服务器中显示报告中的所有数据
