报告数据不显示-WPF

Question

我刚刚开始在WPF中制作报告，但出现以下错误

An error occurred during local report processing. The report definition for report 'Project Path' has not been specified. Could not nto fild file 'File Path'

这是我的代码

private void Window_Loaded(object sender, RoutedEventArgs e)
    {
        List<Model.TruckDriver> truckDriver   = BLL.TruckDriver.GetTruckDriversList(2);
        ReportViewer reportViewer = new ReportViewer();
        reportViewer.ProcessingMode = ProcessingMode.Local;
        reportViewer.LocalReport.ReportPath = "Report1.rdlc";

        ReportDataSource ds = new ReportDataSource("ReportViewer_Driver", truckDriver);
        reportViewer.LocalReport.DataSources.Add(ds);
        reportViewer.RefreshReport();
        windowsFormsHost1.Child = reportViewer;
    }

可能是什么问题？

谢谢

Answer 1

也许在输出目录中没有文件Report1.rdlc ？ 如果以调试方式进行编译，则它必须位于bin / debug -directory中，而在发行版中，它必须位于bin / release中 。

如果这是问题所在，请查看此帖子。 可能会有所帮助。
