Answer 1

first add EPPLUS reference library into application and add using OfficeOpenXml;

//business object class

class bocls {

    string name;

    public string NAME
    {
        get { return name; }
        set { name = value; }
    }
    string id;

    public string ID
    {
        get { return id; }
        set { id = value; }
    }



    public bocls() { }
    public bocls(string name, string id)
    {
        this.name = name;
        this.id = id;         

    }

//in export button click event

protected void lbtnExport_Click(object sender, EventArgs e) {

            List list6 =  new List();
           //copy the grid view values into list
            list6 = (from row in dataGridView1.Rows.Cast()
            from cell in row.Cells.Cast()
            select new 
            {
                //project into your new class from the row and cell vars.
            }).ToList();
    }
            ExcelPackage excel = new ExcelPackage();
            var workSheet = excel.Workbook.Worksheets.Add("Products");
            var totalCols = GridView1.Rows[0].Cells.Count;
            var totalRows = GridView1.Rows.Count;
            var headerRow = GridView1.HeaderRow;
            for (var i = 1; i <= totalCols; i++)
            {
                workSheet.Cells[1, i].Value = headerRow.Cells[i - 1].Text;
            }
            for (var j = 1; j <= totalRows; j++)
            {
                for (var i = 1; i <= totalCols; i++)
                {
                    var item = list6.ElementAt(j - 1);

                    workSheet.Column(1).Width = 13;
                    workSheet.Column(2).Width = 10;

                    workSheet.Cells[j + 1, i].Style.WrapText = true;

                    if (headerRow.Cells[i - 1].Text == "ID")
                        workSheet.Cells[j + 1, i].Value = item.GetType().GetProperty("id").GetValue(item, null);
                    else if (headerRow.Cells[i - 1].Text == "NAME")
                        workSheet.Cells[j + 1, i].Value = item.GetType().GetProperty("name").GetValue(item, null);

                    workSheet.Cells[j + 1, i].Value = workSheet.Cells[j + 1, i].Value.ToString().Replace("
", "");
                }
            }
            using (var memoryStream = new MemoryStream())
            {

                Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
                string filename = Guid.NewGuid().ToString() + ".xlsx";
                Response.AddHeader("content-disposition", "attachment;  filename=" + filename);
                excel.SaveAs(memoryStream);   
                //add your destination folder
                FileStream fileStream = new FileStream(@"C:\Users\karthi\Downloads\New folder\" + filename, FileMode.Create,FileAccess.Write,FileShare.Write);
                memoryStream.WriteTo(fileStream);
                fileStream.Close();
                memoryStream.WriteTo(Response.OutputStream);
                memoryStream.Close();
                memoryStream.WriteTo(Response.OutputStream);
                Response.Flush();
                Response.End();
            }

    }
