将工作表转换为内存流？

Question

我想将工作表转换为内存流，以便我可以在浏览器中下载excel。

Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();

            // Create empty workbook
            excel.Workbooks.Add();

            // Create Worksheet from active sheet
            Microsoft.Office.Interop.Excel._Worksheet workSheet = excel.ActiveSheet;

            try
            {
                // ------------------------------------------------
                // Creation of header cells
                // ------------------------------------------------
                workSheet.Cells[1, "A"] = "GroupId";
                workSheet.Cells[1, "B"] = "Time";



                // ------------------------------------------------
                // Populate sheet with some real data from "cars" list
                // ------------------------------------------------
                int row = 2; // start row (in row 1 are header cells)
                foreach (var item in Result)
                {
                    workSheet.Cells[row, "A"] = item.MasterID;
                    workSheet.Cells[row, "B"] = item.LocalTime;  
                    row++;
                }

我知道转换成内存流但是在这里

 using (MemoryStream exportData = new MemoryStream())
                {

                    //workSheet.Write(exportData);  //Worksheet doesn't have this Write method as compared to workbook.
                    Response.ContentEncoding = Encoding.GetEncoding("ISO-8859-1");
                    Response.Charset = Encoding.GetEncoding("ISO-8859-1").EncodingName;
                    Response.ContentType = "application/vnd.ms-excel"; //xls
                                                                       // For xlsx, use: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
                    Response.AddHeader("content-disposition", String.Format("attachment; filename={0}.xls", "yourFilename"));
                    Response.Clear();
                    Response.BinaryWrite(exportData.GetBuffer());
                    Response.End();
                }

如何将我的工作表转换为内存流？

Answer 1

找不到Microsoft.Office.Interop.Excel的解决方案。除了文件应首先保存在计算机上，而不是流保存为红色。

Spire.xsl有一个方法

workbook.SaveToStream（memoryStream，FileFormat.Version2016）;

注意：spire.xsl免费版本有限制。
