Refer: Click here[^]

Try this:

C#

//Create a workbook
Workbook workbook = new Workbook();           
//Load the file
workbook.LoadFromFile("DataTableSample.xls");

//Initailize worksheet
Worksheet sheet = workbook.Worksheets[0];

//Export datatable
DataTable dataTable = sheet.ExportDataTable();

[EDIT]

Have a look on this CP Article: Import Excel File to DataSet[^]

before page load define the properties of msexcel-

public int StateId;
  DataSet ds = new DataSet();
  Thread th2;
  DataSet myDs = new DataSet();
  string fu = null;
  int result;


      Microsoft.Office.Interop.Excel.Application oXL = new Microsoft.Office.Interop.Excel.Application();
      Microsoft.Office.Interop.Excel.ApplicationClass app = new Microsoft.Office.Interop.Excel.ApplicationClass();
      Microsoft.Office.Interop.Excel.Workbook oWB;
      Microsoft.Office.Interop.Excel.Worksheet oSheet;

then take your first sheet data into dataset -

protected void FillDataSet()
 {

     try
     {

         string strFilename = FileUpload.PostedFile.FileName;
         strFilename = System.IO.Path.GetFileName(strFilename);
         string ext = Path.GetExtension(strFilename);
         bool hasHeaders = true;
         string HDR = hasHeaders ? "Yes" : "No";
         string strConn;



         if (ext.ToLower() == ".xls")
         {

             //strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fu + ";Extended Properties=Excel 8.0;";
             strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fu + " ;Extended Properties=\"Excel 8.0;HDR=" + HDR + ";IMEX=1\"";
             Microsoft.Office.Interop.Excel.WorkbookClass workBook = (Microsoft.Office.Interop.Excel.WorkbookClass)app.Workbooks.Open(fu, 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
             oSheet = (Microsoft.Office.Interop.Excel.Worksheet)workBook.ActiveSheet;
             app.Visible = false;

             OleDbDataAdapter myCmd = new OleDbDataAdapter("SELECT * FROM [" + oSheet.Name + "$]", strConn);
             myCmd.Fill(myDs);
             string source = @"F:\yourdrive\" + strFilename;
             string target = @"F:\yourdrive\temp\" + strFilename;

             if (File.Exists(target))
                 File.Delete(target);
             File.Move(source, target);
         }

         if (ext.ToLower() == ".xlsx")
         {


             //strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fu + ";Extended Properties=Excel 8.0;";
             strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fu + ";Extended Properties=\"Excel 12.0;HDR=" + HDR + ";IMEX=2\"";
             Microsoft.Office.Interop.Excel.WorkbookClass workBook = (Microsoft.Office.Interop.Excel.WorkbookClass)app.Workbooks.Open(fu, 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
             oSheet = (Microsoft.Office.Interop.Excel.Worksheet)workBook.ActiveSheet;
             app.Visible = false;
             //You must use the $ after the object you reference in the spreadsheet
             OleDbDataAdapter myCmd = new OleDbDataAdapter("SELECT * FROM [" + oSheet.Name + "$]", strConn);
             myCmd.Fill(myDs);
             string source = @"F:\yourdrive\" + strFilename;
             string target = @"F:\yourdrive\temp\" + strFilename;
             //if (File.Exists(source))
             //File.Delete(source);



             if (File.Exists(target))
                 File.Delete(target);
             File.Move(source, target);


         }
     }
     catch (Exception ex)
     {
         // objError.sendMail("Error on ReadExcel.aspx", "<b>" + ex.Message.ToString() + "</b>" + "<br/>" + ex.Source.ToString() + " " + ex.TargetSite + "<br/>" + ex.StackTrace);
         Response.Write("Error has been sent to the Technical Team, Please try after some time!");
     }
 }

after when your data is in dataset ... you can insert this in your database on buton click .
