创buildEXCEL并打开它
我正在创build一个excel文件，我必须立即打开它。 显然，当我在本地创build它，我可以得到的文件，但是当我在IIS上发布我的Web应用程序这不工作，因为我想它是在服务器端创build…
所以我创build的Excel文件，并尝试上传到服务器，然后下载它，但我不能创build它，如果我在本地运行这个工作，但是当我发布不工作。
有什么build议？
这是我的代码：
我使用这个Excel的库：
using Microsoft.Office.Core; using Excelo = Microsoft.Office.Interop.Excel; using Microsoft.Office.Interop; using System.Reflection; using System.Globalization; 然后，我开始我的Excel文件：
private void sacConsulPend_GenRemito() { // DB string conn = ConfigurationManager.ConnectionStrings["conn"].ConnectionString; DataSet dsRemito = new DataSet(); DataTable dtCons = new DataTable(); using (SqlConnection sqlCon = new SqlConnection(conn)) { using (SqlCommand cmd = new SqlCommand()) { try { //SP for data query cmd.CommandType = System.Data.CommandType.StoredProcedure; cmd.CommandText = "SACBUS_CONSUL_SOLICITUDEXIST"; cmd.Parameters.AddWithValue("@ID_CONSULTA", Convert.ToInt32(lblSac_ConPenDet_idCons.Text.Replace(" ", ""))); cmd.Connection = sqlCon; sqlCon.Open(); SqlDataAdapter dapC = new SqlDataAdapter(cmd); dapC.Fill(dsRemito); } catch (Exception sqlex) { throw sqlex; } } } Excelo.Application oXL; Excelo._Workbook oWB; Excelo._Worksheet oSheet; Excelo.Range oRng; try { //Start Excel oXL = new Excelo.Application(); //new blank workbook. oWB = (Excelo._Workbook)(oXL.Workbooks.Add(System.Reflection.Missing.Value)); oSheet = (Excelo._Worksheet)oWB.ActiveSheet; object misValue = System.Reflection.Missing.Value; //Text Format oSheet.get_Range("A1", "Z1000").Font.Name = "Courier New"; oSheet.get_Range("A1", "Z1000").Font.Size = 7; oSheet.get_Range("A1", "Z1000").Font.Bold = true; oSheet.get_Range("A1", "Z1000").NumberFormat = "@"; oSheet.get_Range("D1", "E1").Cells.Merge(); oSheet.get_Range("A1", "F1").Font.Bold = true; oSheet.get_Range("A1", "F1").Font.Italic = true; oSheet.get_Range("A1", "F1").VerticalAlignment = Excelo.XlVAlign.xlVAlignCenter; oSheet.get_Range("A1", "F1").HorizontalAlignment = Excelo.XlVAlign.xlVAlignCenter; oSheet.get_Range("A1", "F1").Font.Size = 9; //Logo Lockers oSheet.Shapes.AddPicture(Server.MapPath("~/images/LockersLogo.jpg"), MsoTriState.msoFalse, MsoTriState.msoCTrue, 0, 0, 60, 20); /* Excel Content */ //Save ExcelFile var filePath = Path.Combine(HttpContext.Current.Server.MapPath("~/Files/Envios/"), lblSac_ConPenDet_idCons.Text.Replace(" ", "") + ".xlsx"); oWB.SaveAs(filePath, Excelo.XlFileFormat.xlOpenXMLWorkbook, Missing.Value, Missing.Value, false, false, Excelo.XlSaveAsAccessMode.xlNoChange, Excelo.XlSaveConflictResolution.xlUserResolution, true, Missing.Value, Missing.Value, Missing.Value); } catch (Exception thex) { String errorMessage; errorMessage = "Error en la creacion del archivo Excel: "; errorMessage = String.Concat(errorMessage, thex.Message); errorMessage = String.Concat(errorMessage, " Line: "); errorMessage = String.Concat(errorMessage, thex.Source); } }
您可以使用适用于您的场景的（官方） OpenXML SDK 。 它不允许您实际计算和运行服务器环境中的函数，但它适用于创build和操作工作簿。 下载然而，OpenXML SDK并不是每个人都喜欢的，因为它需要一些学习，有时还有很多代码来实现一些简单的事情。
幸运的是，还有许多其他库允许在没有Office的情况下创buildXLS / X文件，如ExcelLibrary或其后续的EEPlus或NPOI （请参阅johnleniel ）以及许多商业第三方组件。
我可以想象，像Crystal Reports这样的专门的报表组件（也可以导出到XLS / X）对你来说也是非常有用的。
这是我的代码，使用EEPlus它没有完成，但工作，在服务器端创build一个文件，之后，我下载了相同的创build文件。
using OfficeOpenXml; using System.IO; using System.Drawing; using OfficeOpenXml.Drawing; using System.Data; using System.Data.SqlClient; using System.Configuration;
