问题 I wrote a code to read a column from a Excel file. I use Microsoft.Office.Interop.Excel on this, first read the entire Range and then write in System.Array after that I do some operations with the System.Array values and finally I convert it to List because I fill a ListBox element. This is the code (only relevant parts): private List<string> bd = new List<string>(); private static System.Array objRowAValues; private List<string> bl = new List<string>(); private static System.Array

问题 I'm using the EPPLUS library to read data from Excel to create another file. Unfortunately it does not support the .XLSM extension file. Is there a nice way to convert .XLSM files to .XLSX file for the purpose of reading the file with EPPLUS? (using EPPLUS for reading would be nice because all my code is already written using it :) ) 回答1: In order to do this you will need to use the Open XML SDK 2.0. Below is a snippet of code that worked for me when I tried it: byte[] byteArray = File

问题 I am having issues unit testing classes that use EPPlus. In my mind, I have two options. I can mock & inject the HttpPostedFileBase into a method, or I can mock & inject the EPPlus ExcelPackage class. Mocking the HttpPostedFileBase, at least doing a true mock, seems limited. I can mock the basic properties on the file (MIME type, filename, etc), but to mock its InputStream in a way that allows the tests to actually interact with it, seems extremely difficult. The only solution I can come up

You can get more info from here: How to get temporary folder for current user So, something like this
