                Microsoft.Office.Interop.Excel._Worksheet oSheet;
                Microsoft.Office.Interop.Excel.Range oRng;
                object misvalue = System.Reflection.Missing.Value;
                try
                {
                    //Start Excel and get Application object.
                    oXL = new Microsoft.Office.Interop.Excel.Application();
                    oXL.Visible = true;

                    //Get a new workbook.
                    oWB = (Microsoft.Office.Interop.Excel._Workbook)(oXL.Workbooks.Add(""));
                    oSheet = (Microsoft.Office.Interop.Excel._Worksheet)oWB.ActiveSheet;

                    //Add table headers going cell by cell.
                    oSheet.Cells[1, 1] = "First Name";
                    oSheet.Cells[1, 2] = "Last Name";
                    oSheet.Cells[1, 3] = "Full Name";
                    oSheet.Cells[1, 4] = "Salary";

                    //Format A1:D1 as bold, vertical alignment = center.
                    oSheet.get_Range("A1", "D1").Font.Bold = true;
                    oSheet.get_Range("A1", "D1").VerticalAlignment =

oWB.SaveAs("c://Vova/test34545.xls", Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookDefault, Type.Missing, Type.Missing,
false, false, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
oWB.Close();

Answer 1

You need to change the path to c:\\\\Vova\\\\test34545.xlsx and then disable pop up set :

oXL.Visible = false;
oXL.UserControl = false;

Answer 2

try this code

 Microsoft.Office.Interop.Excel.Application xlApp = null;
        Microsoft.Office.Interop.Excel.Workbook xlWorkBook = null;
        Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet;
        object misValue = System.Reflection.Missing.Value;
        xlApp = new Microsoft.Office.Interop.Excel.ApplicationClass();
        xlWorkBook = xlApp.Workbooks.Add(misValue);

        xlWorkSheet = (Microsoft.Office.Interop.Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
        xlWorkSheet.Cells[1, 1] = "ArsalanQaiser";
        string fileName = "Excel.xls";
        string path = "D:\\" + fileName;
        xlWorkBook.SaveAs(path, Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
        xlWorkBook.Close(true, misValue, misValue);
        xlApp.Quit();

        FileInfo file = new FileInfo(path);
        if (file.Exists)
        {
            Response.Clear();
            Response.ClearHeaders();
            Response.ClearContent();
            Response.AddHeader("content-disposition", "attachment; filename=" + fileName);
            Response.AddHeader("Content-Type", "application/Excel");
            Response.ContentType = "application/vnd.xls";
            Response.AddHeader("Content-Length", file.Length.ToString());
            Response.WriteFile(file.FullName);
            Response.End();
        }
        else
        {
            Response.Write("This file does not exist.");
        }
    }
