问题描述

在报告中分配数据源时抛出 System.IO.FileNotFoundException execption.我正在使用 Visual Studio 2013、C# 4.5、WinForm 应用程序.我已经为 Visual Studio 13 安装了 Crystal Report.

System.IO.FileNotFoundException execption thrown while assigning data source in report. I am using visual studio 2013, C# 4.5, WinForm application. I have installed crystal report for visual studio 13.

这是代码

    DataSet ds = new DataSet();
    ds.Tables.Add(new DataTable("administration_CashDeskManager_Reports_ReportDataBusinessObject"));
    ds.Tables.Add(new DataTable("administration_CashDeskManager_Reports_ReportDataDetailBusinessObject"));

    Reports.CrystalReport.rptCashDeskTransactionLog Report = new Reports.CrystalReport.rptCashDeskTransactionLog();
    Report.SetDataSource(ds);
    crViewer.ReportSource = Report;

Report.SetDataSource(ds) 命令引发错误.

我认为这个错误是特定于版本的错误.

I think this error is version specific error.
