Question

我有一个C＃Web表单应用程序，我想使用Open XML SDK 2.5将gridview的内容导出到excel。当我在localhost中运行时这很好用，但是当我将我的应用程序移动到UAT网络服务器时它没有工作，我没有收到任何错误。我认为这是一个提示错误但不确定。谢谢，

 DocumentFormat.OpenXml.Packaging.SpreadsheetDocument spreadsheet;
        DocumentFormat.OpenXml.Spreadsheet.Worksheet worksheet;
        System.IO.StreamReader styleXmlReader;
        string styleXml;

        spreadsheet = Excel.CreateWorkbook(workbookName);
        if (spreadsheet == null)
        {
            return;
        }

        if (createStylesInCode)
        {
            Excel.AddBasicStyles(spreadsheet);
        }
        else
        {
            using (styleXmlReader = new     
  System.IO.StreamReader("PredefinedStyles.xml"))
            {
                styleXml = styleXmlReader.ReadToEnd();
                Excel.AddPredefinedStyles(spreadsheet, styleXml);
            }
        }

        Excel.AddSharedString(spreadsheet, "Shared string");
        Excel.AddWorksheet(spreadsheet, "Test 1");
        Excel.AddWorksheet(spreadsheet, "Test 2");
        worksheet = 
spreadsheet.WorkbookPart.WorksheetParts.First().Worksheet;

        // Headings
        Excel.SetCellValue(spreadsheet, worksheet, 1, 1, "QMS Area", 
true);
        Excel.SetCellValue(spreadsheet, worksheet, 2, 1, "Division 
Owner", true);
        Excel.SetCellValue(spreadsheet, worksheet, 3, 1, "Relevant 
Divisions", true);
        Excel.SetCellValue(spreadsheet, worksheet, 4, 1, "Audit Team", 
true);
        Excel.SetCellValue(spreadsheet, worksheet, 5, 1, "Audit Date", 
true);


        int _rowCount = 2;
        foreach (var audit in _auditDetails)
        {
            // Set Values
            Excel.SetCellValue(spreadsheet, worksheet, 1, 
(uint)_rowCount, audit.QmsArea, true);
            Excel.SetCellValue(spreadsheet, worksheet, 2, 
(uint)_rowCount, audit.DivisionOwner ?? "", true);
            Excel.SetCellValue(spreadsheet, worksheet, 3, 
(uint)_rowCount, audit.RelevantDivision ?? "", true);
            Excel.SetCellValue(spreadsheet, worksheet, 4, 
(uint)_rowCount, audit.AuditTeam ?? "", true);
            Excel.SetCellValue(spreadsheet, worksheet, 5, 
(uint)_rowCount, audit.AuditDate.ToString() ?? "", true);             
            _rowCount++;
        }



        // Set column widths
        Excel.SetColumnWidth(worksheet, 1, 15);
        Excel.SetColumnWidth(worksheet, 2, 20);

        worksheet.Save();
        spreadsheet.Close();


        System.Diagnostics.Process.Start(workbookName);

我会检查保存excel文件的服务器上的文件夹权限。您需要确保您的Web应用程序具有该文件夹的读/写权限。

它在本地计算机上运行，而不是在托管环境中运行，这让我觉得文件夹权限可能是问题所在。

Open SDK在Web服务器上运行但无法在localhost中运行时无法打开Excel文件
