I am familiar with Excel VBA but new to C# and Visual Basicvisula Studio. I have an Excel file (.xlsm) with several sheets. Using ExcelDataReader, I managed to build a solution to show all sheet names in a combobox control. I need help in how can I import the selected sheet content in combobox (cboSheet) to the datagridview1

using ExcelDataReader;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.IO;
using System.Data.SqlClient;

namespace ReadandImportsheet1
{
public partial class Form1 : Form
{
    
    
    private readonly object con;
    

    public object Break { get; private set; }

    public Form1()
    {
        InitializeComponent();
    }

    public Form1(object con)
    {
        this.con = con;
    }

    private void button1\_Click(object sender, EventArgs e)
    {
        OpenFileDialog fil = new OpenFileDialog();
        fil.ShowDialog();
        string path = fil.FileName.ToString();
        ExcelFileReader(path);
    }
    public void ExcelFileReader(string path)
    {
        var stream = File.Open(path, FileMode.Open, FileAccess.Read);
        var reader = ExcelReaderFactory.CreateReader(stream);
        var result = reader.AsDataSet();
        var tables = result.Tables;
        foreach (DataTable table in tables)
        {
            cboSheet.Items.Add(table.TableName);
        }
        //var shname = cboSheet.SelectedValue;
        //string table\_name = cboSheet.Text;
    }

    private void cboSheet\_SelectedIndexChanged(object sender, EventArgs e)
    {
        string table\_name = cboSheet.Text;
        SqlConnection Con = new SqlConnection("Provider = Microsoft.ACE.OLEDB.12.0; Data Source = path; Extended Properties = "Excel 8.0; HDR = YES";");
        con.Open();
        SqlDataAdapter da = new SqlDataAdapter("select \* from " + table\_name + " ", con);
        DataSet ds = new DataSet();
        da.Fill(ds);
        dataGridView1.DataSource = ds.Tables\[0\];
        dataGridView1.DataBind();

        con.Close();
    }
}

}

I am using Win 11 and Visual Studio 2019 with ExcelDataReade
