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

background

a few days ago, i was required to read excel files and store those values in our sql server database. so, in this example am going to show how to get four basic import data types: 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 below.

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;  
    }  

}
