Question

我正在使用PdfReport库生成报告.pdf文件。 PdfReport是一个基于Epplus和iTextsharp的库，这就是我们选择这个库的原因 - 因为我们想要生成PDF和EXCEL文件。

目前我们能够生成生成的PDF文件似乎无法生成Excel文件。

Google对这个图书馆的帮助不大。

这是我的代码

public class IListPdfReport
{
    public IPdfReportData CreatePdfReport(DataSet mTables)
    {
        return new PdfReport().DocumentPreferences(doc =>
        {
            doc.RunDirection(PdfRunDirection.LeftToRight);
            doc.Orientation(PageOrientation.Portrait);
            doc.PageSize(PdfPageSize.A4);
            doc.DocumentMetadata(new DocumentMetadata { Author = "Vahid", Application = "PdfRpt", Keywords = "IList Rpt.", Subject = "Test Rpt", Title = "Test" });
            doc.Compression(new CompressionSettings
            {
                EnableCompression = true,
                EnableFullCompression = true
            });
            doc.PrintingPreferences(new PrintingPreferences
            {
                ShowPrintDialogAutomatically = true
            });
        })
        .DefaultFonts(fonts =>
        {
            fonts.Path(System.IO.Path.Combine(Environment.GetEnvironmentVariable("SystemRoot"), "fonts\\arial.ttf"),
                       System.IO.Path.Combine(Environment.GetEnvironmentVariable("SystemRoot"), "fonts\\verdana.ttf"));
            fonts.Size(9);
            fonts.Color(System.Drawing.Color.Black);
        })
        .PagesFooter(footer =>
        {
            footer.DefaultFooter(DateTime.Now.ToString("MM/dd/yyyy"));
        })
        .MainTableTemplate(template =>
        {
            template.BasicTemplate(BasicTemplate.AppleOrchardTemplate);
        })
        .MainTablePreferences(table =>
        {
            table.ColumnsWidthsType(TableColumnWidthType.FitToContent);
            table.NumberOfDataRowsPerPage(10);
        })
        .MainTableDataSource(dataSource =>
        {
            dataSource.DataTable(mTables.Tables[2]);
        })
        .MainTableSummarySettings(summarySettings =>
        {
            summarySettings.OverallSummarySettings("Summary");
            summarySettings.PreviousPageSummarySettings("Previous Page Summary");
            summarySettings.PageSummarySettings("Page Summary");
        })
        .MainTableColumns(columns =>
        {
            columns.AddColumn(column =>
            {
                column.PropertyName("AssetSummaryReportDetailId");
                column.IsRowNumber(true);
                column.CellsHorizontalAlignment(HorizontalAlignment.Center);
                column.IsVisible(true);
                column.Order(0);
                column.Width(1);
                column.HeaderCell("AssetSummaryReportDetailId");
            });

            columns.AddColumn(column =>
            {
                column.PropertyName("AssetId");
                column.IsRowNumber(true);
                column.CellsHorizontalAlignment(HorizontalAlignment.Center);
                column.IsVisible(true);
                column.Order(1);
                column.Width(2);
                column.HeaderCell("AssetId");
            });

            columns.AddColumn(column =>
            {
                column.PropertyName("CategoryId");
                column.IsRowNumber(true);
                column.CellsHorizontalAlignment(HorizontalAlignment.Center);
                column.IsVisible(true);
                column.Order(1);
                column.Width(2);
                column.HeaderCell("CategoryId");
            });




        })
        .MainTableEvents(events =>
        {
            events.DataSourceIsEmpty(message: "There is no data available to display.");
        })
        .Export(export =>
        {

// This line here should generate the Excel file, but it is not creating the Excel file
            export.ToExcel(description: "Demo", fileName: "usmandemo.xlsx", worksheetName: "worksheet1", footer: "footer");
        })
        .Generate(data => data.AsPdfFile(string.Format("{0}\\A_RptIListSample-{1}.pdf", AppPath.ApplicationPath, Guid.NewGuid().ToString("N"))));

    }
