Ошибка при вставке данных листа excel в базу данных

---

The Microsoft Access database engine cannot open or write to the file ''. It is already opened exclusively by another user, or you need permission to view and write its data.

в следующем коде он выдает ошибку при

excelConnection.Open();

Что я уже пробовал:

Таблица базы данных содержит следующие столбцы
1) Id
2) имя
Обозначение

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

using System.Data;
using System.Data.OleDb;
using System.Data.SqlClient;

namespace WebApplication5
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void btnSend_Click(object sender, EventArgs e)
        {
            String strConnection = "Data Source=DESKTOP-HL3PK63;Initial Catalog=Demo;Integrated Security=True";
            //file upload path
            string path = fileuploadExcel.PostedFile.FileName;
            //Create connection string to Excel work book
            string excelConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 12.0;Persist Security Info=False";
            //Create Connection to Excel work book
            OleDbConnection excelConnection = new OleDbConnection(excelConnectionString);
            //Create OleDbCommand to fetch data from Excel
            OleDbCommand cmd = new OleDbCommand("Select [ID],[Name],[Designation] from [Sheet1$]", excelConnection);
            excelConnection.Open();
            OleDbDataReader dReader;
            dReader = cmd.ExecuteReader();
            SqlBulkCopy sqlBulk = new SqlBulkCopy(strConnection);
            //Give your Destination table name
            sqlBulk.DestinationTableName = "Excel_table";
            sqlBulk.WriteToServer(dReader);
            excelConnection.Close();
        }
    }
}
