Imprimer le contenu d'un DataTable

tu peux essayer ce code :

foreach(DataRow dataRow in Table.Rows)
{
    foreach(var item in dataRow.ItemArray)
    {
        Console.WriteLine(item);
    }
}

DataTable Table = new DataTable("TestTable");
using(SqlCommand _cmd = new SqlCommand(queryStatement, _con))
{
    SqlDataAdapter _dap = new SqlDataAdapter(_cmd);
    _con.Open();
    _dap.Fill(Table);
    _con.Close();

}
Console.WriteLine(Table.Rows.Count);
foreach(DataRow dataRow in Table.Rows)
{
    foreach(var item in dataRow.ItemArray)
    {
        Console.WriteLine(item);
    }
}
