How to Import All Excel Sheet in Gridview in asp.net?

Question

我已经在excel中创建了一个出勤表，我想在gridview中显示所有表格，例如班级出勤报告，学生出勤报告等，有人可以帮我吗？

Answer 1

You should import your sheets into a DataSet object, and then bind it to a GridView.
Take a look at those links:
Excel Sheet to DataSet: link_1
Bind DataSet to Gridview: link_2

Answer 2

   List<string> excelName = new List<string>();   
   DataSet ds = new DataSet();  
   foreach(var name in excelName )
    {
        using (SqlConnection con = new SqlConnection(connectionString))
        {        
            DataTable dt = new DataTable();
            string query ="select * from '"+name+"'";
            con.Open();
            SqlDataAdapter da = new OleDbDataAdapter(query, con);
            da.Fill(dt);
            con.Close();    
            ds.add(dt);            
        }
    }

    gridview.DataSource = ds;
    gridview.DataBind();
