使用ASP.NET MVC中的验证将记录从Excel工作表导入SQL Server

Question

I'm just following this tutorial to import records from an Excel sheet into SQL Server with validations.

It's done using Webforms, here I'm trying to do it using asp.net mvc 5

This is the controller class

This is the Viewpage file

But here I'm getting following errors

The name 'uploaddata' does not exist in the current context

Getting this error in ImporttoDatatable() method

The name 'gvEmployee' does not exist in the current context

Getting this error in BindGrid() method

'Page' is a type, which is not valid in the given context

Getting this error in CheckData() method

Answer 1

So if you are using MVC5 you should be using Data Annotations on a view model/model for validation. Instead of creating all the methods to do it for you, see here https://msdn.microsoft.com/en-us/library/dd901590(VS.95).aspx . I also recommend using the open source library DocumentFormat.OpenXml and the SpreadSheetDocument class for reading in a spreadsheet its much easier

 using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Open("filename", false))
        {
            WorkbookPart workbookPart = spreadsheetDocument.WorkbookPart;
            WorksheetPart workSheetPart = workbookPart.WorksheetParts.First();
            var sheetData = workSheetPart.Worksheet.Descendants<Row>();
        }
