Read Excel Files Using Microsoft Office Interop Assemblies in ASP.NET C#

In this article you will learn how to Read Excel Files Using Microsoft Office Interop Assemblies in ASP.NET C#.

Background

A few days ago I got a requirement to read Excel files and store those values in the Sql server database. So in this example am going to show how to get the basic four import datas such as Excel Work Book Name, Worksheet Count in that Workbook, Name of the First Worksheet, and finally the value of the first cell in that worksheet.

Prerequisites

Kindly ensure you add the following dll as shown in the below screenshot,





Namespace

using Excel = Microsoft.Office.Interop.Excel;

C# Code

protected void BtnGetExcelFileDetails_Click(object sender, EventArgs e)
{

    try
    {
        //create a instance for the Excel object
        Excel.Application oExcel = new Excel.Application();

        //specify the file name where its actually exist
        string filepath = @ "D:\TPMS\Uploaded_Boq\Raveena_boq_From_Db.xlsx";

        //pass that to workbook object
        Excel.Workbook WB = oExcel.Workbooks.Open(filepath);


        // statement get the workbookname
        string ExcelWorkbookname = WB.Name;

        // statement get the worksheet count
        int worksheetcount = WB.Worksheets.Count;

        Excel.Worksheet wks = (Excel.Worksheet) WB.Worksheets[1];

        // statement get the firstworksheetname

        string firstworksheetname = wks.Name;

        //statement get the first cell value
        var firstcellvalue = ((Excel.Range) wks.Cells[1, 1]).Value;

    } catch (Exception ex)
    {

        string error = ex.Message;
    }

}
