Question

Can someone provide a link with a tutorial about exporting data to an excel file using c# in an asp.net web application.I searched the internet but I didn’t find any tutorials that will explain how they do it.

Answer 1

You can use Interop http://www.c-sharpcorner.com/UploadFile/Globalking/datasettoexcel02272006232336PM/datasettoexcel.aspx

Or if you don’t want to install Microsoft Office on a webserver
I recommend using CarlosAg.ExcelXmlWriter which can be found here: http://www.carlosag.net/tools/excelxmlwriter/

code sample for ExcelXmlWriter:

using CarlosAg.ExcelXmlWriter;

class TestApp {
    static void Main(string[] args) {
        Workbook book = new Workbook();
        Worksheet sheet = book.Worksheets.Add("Sample");
        WorksheetRow row =  sheet.Table.Rows.Add();
        row.Cells.Add("Hello World");
        book.Save(@"c:\test.xls");
    }
}
