closedxml

问题 I am inserting data into a dummy excel. I need to append symbols before texts into some cell. Please let me know how can i achieve this using ClosedXML. 回答1: In ClosedXML, you can set this value with this code: ws.Cell(1, 1).Value = "❶ Symbol"; To enter the ❶, you can use the Windows program Character Map to select and copy the appropriate character. 来源： https://stackoverflow.com/questions/39489347/how-can-i-add-symbols-to-a-cell-using-closedxml

问题 I am looking for a library that allows me to read an Excel document in C#, but I am needing to be able to read the cell formatting as well as the data in the spreadsheet.

For my particular problem, though, I am needing to read a document that

Here is my code: public ActionResult ExportExcel() { MemoryStream stream = nModel.GenerateSS(); return File(stream, @"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

问题 I am working on a ASP.NET 4.5 Webform and I have a Gridview (that has custom TemplateField and gets data from a sqlDataSource) I have this event to export the gridview contents to an excel sheet, and it does its jobs well except the created file is giving out an warning when user open it (which I understand because the file that got created is not an actual excel file): "the file you are trying to open is in a different format than specified by the file extension" protected void btnExport

问题 In my ASP.NET MVC project, I generated a excel file using ClosedXML. It works well in non-ajax call.

I'd like to avoid using InterOp since I might batch this process on multiple files through a network. EDIT: According to some old pages from 2009, there are limitations where OpenXML cannot operate protected files.
