2、從文件流打開：

using System.IO;
using DevExpress.Spreadsheet;
// ...
Workbook workbook = new Workbook();
// Load a workbook from the stream.
using (FileStream stream = new FileStream("Documents\\Document.xlsx", FileMode.workbook.LoadDocument(stream, DocumentFormat.OpenXml);
}

如何將文檔保存到文件

1、另存爲文件：

workbook.SaveDocument("Documents\\SavedDocument.xlsx", DocumentFormat.OpenXml);

2、保存到文件流：

using System.IO;
using DevExpress.Spreadsheet;
// ...
Workbook workbook = new Workbook();
// ...
// Save the modified document to the stream.
using (FileStream stream = new FileStream("Documents\\SavedDocument.xlsx",
FileMode.Create, FileAccess.ReadWrite)) {
workbook.SaveDocument(stream, DocumentFormat.OpenXml);

如何將Workbook保存爲PDF格式

(ExportActions.cs)
using (FileStream pdfFileStream = new FileStream("Documents\\Document_PDF.pdf", FileMode.Create))
{
workbook.ExportToPdf(pdfFileStream);
}

如何將將Workbook保存爲HTML格式

Worksheet worksheet = workbook.Worksheets["Grouping"]; workbook.Worksheets.ActiveWorksheet = worksheet; HtmlDocumentExporterOptions options = new HtmlDocumentExporterOptions(); // Specify the part of the document to be exported to HTML. options.SheetIndex = worksheet.Index; options.Range = "B2:G7"; // Export the active worksheet to a stream as HTML with the specified options. using (FileStream htmlStream = new FileStream("OutputWorksheet.html", FileMode.Create)) { workbook.ExportToHtml(htmlStream, options); } System.Diagnostics.Process.Start("OutputWorksheet.html");
