Hi Mon,
We also could use OleDbConnection to insert data into excel.
using System.Data.OleDb;
using Excel = Microsoft.Office.Interop.Excel;
using Microsoft.Office.Interop;
//in the method section use as :
string datevariable = "02/02/2010";
string namevariable = "Shyam";
string strConnectionString ="";
string cmd;
string filepath = ""C:\\sample.xls";
strConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+filePath+@";Extended Properties=""Excel 8.0;HDR=Yes;""" ;
OleDbConnection conn =new OleDbConnection (strConnectionString);
try
conn.Open();
catch(Exception e)
Console.WriteLine(e);
try
// Insert into Sheetname
cmd = "Insert into [Sheet1$] ( [Date], [Name]) values ('" +datevariable+ "','" +namevariable+ "');
//Similarly you can update also
OleDbCommand cmdUpd=new OleDbCommand(cmd);
cmdUpd.Connection = conn;
cmdUpd.ExecuteNonQuery();
conn.Close();
catch(Exception e)
Console.WriteLine(e);
