Unable to create the excel file after publishing the c# code

Question

Unable to create the excel file after publishing the c# code in IIS Server. Although it works in local App

Nilesh Shah · Answer

there must be some error somewhere, r u logging any errors? most of the local\dev. PCs have MS Office already installed so any code dealing with excel works fine the server may not have MS Office installed, that's why the same code does not work on server. you may need to install/place excel com interop dll on server.

DataSet dtvendor = new DataSet(); SqlDataAdapter da = new SqlDataAdapter( "FoodGroupFinalExcelReport" , con); da.Fill(dtvendor); Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application(); excel.Application.Workbooks.Add( true ); System.Data.DataTable table = dtvendor.Tables[0]; int ColumnIndex = 0; Microsoft.Office.Interop.Excel.Worksheet worksheet = (Microsoft.Office.Interop.Excel.Worksheet)excel.ActiveSheet; DataTable dtRepGrpInfo = new DataTable(); foreach (System.Data.DataColumn col in table.Columns) { ColumnIndex++; excel.Cells[1, ColumnIndex] = col.ColumnName; } int rowIndex = 0; foreach (DataRow row in table.Rows) { rowIndex++; ColumnIndex = 0; foreach (DataColumn col in table.Columns) { ColumnIndex++; excel.Cells[rowIndex + 1, ColumnIndex] = row[col.ColumnName]; } } string file = "FoodGroup-" + id + ".xlsx" ; var fileSavePath = Path.Combine(System.Web.HttpContext.Current.Server.MapPath( "~/Reports" ), file); excel.Application.ActiveWorkbook.SaveCopyAs(fileSavePath); Process procStart = new Process(); procStart.StartInfo.FileName = fileSavePath; procStart.Start(); This is my code which is creating an excel file when I am running through visual studio 2013.But My application wants to host in IIS Server, After hosting this code in IIS it is not creating the excel file and it shows page not redirect error. FYI, I don't know how to do debug the code through IIS after publishing it in IIS server.

then you have to find the error/exception, without that it's difficult to help you

In the server, we have already install msoffice.

Try spire.xls instead. It doesn't rely on MS Office. https://www.e-iceblue.com/Introduce/excel-for-net-introduce.html
