流式传输到 Excel 而不保存

我正在创建 excel 并在其中填充值。 我正在使用EPPlus。我可以使用文件流保存它并打开它。但我想在不保存的情况下打开它。我认为我们可以以某种方式使用内存流直接生成 excel。请指导。

try
        {
            MemoryStream newFile = new MemoryStream();
            using (ExcelPackage package = new ExcelPackage(newFile))
            {

                // Add Data Collection worksheet
                ExcelWorksheet dataWorksheet = package.Workbook.Worksheets.Add("Sheet1");

                dataWorksheet.Cells[1, 1].Value = " My Text";
                dataWorksheet.Cells[1, 1].Style.Font.Size = 14;
                dataWorksheet.Cells[3, 1].Value = BALGlobalVariables.cocName;
                dataWorksheet.Cells[5, 1].Value = "IR From Date :";
                dataWorksheet.Cells[6, 1].Value = "IR To Date : ";
                dataWorksheet.Cells[5, 6].Value = "From Date :";
                dataWorksheet.Cells[6, 6].Value = "To Date : ";
                dataWorksheet.Cells[5, 2].Value = fromDate;
                dataWorksheet.Cells[6, 2].Value = toDate;
                dataWorksheet.Cells[5, 7].Value = invFromDate;
                dataWorksheet.Cells[6, 7].Value = invFromDate;


                // Template specific excel generation goes in here
                FillPurchaseExcelData(ref dataWorksheet, masterTable, subTable);
                // save package
                package.Save();
            }
            byte[] fileContent = newFile.ToArray();
#if DEBUG
            string tempName = "MTemp.xlsx";
            string tempFileName = System.IO.Path.GetDirectoryName(Environment.GetCommandLineArgs()[0]) + @"'" + tempName;
            //Write the stream data of workbook to the root directory
            using (FileStream file = new FileStream(tempFileName, FileMode.Create))
            {
                file.Write(fileContent, 0, fileContent.Length);
            }
            System.Diagnostics.Process.Start(tempFileName);
