I have a table and I want to delete all rows with a specific card serial . There are multiple rows with the same card serial .So I wrote this code but it seems that's not working:

try
{
using (SqlConnection con = new SqlConnection(WF_AbsPres.Properties.Settings.Default.DbConnectionString))
{
   con.Open();
   SqlCommand command2 = new SqlCommand("DELETE  FORM DevInOut where Cardserial='" + textBox5.Text + "'", con);
   command2.ExecuteNonQuery();
   con.Close();
}
}
   catch (SqlException ex)
{
}

how can assure all the rows will be deleted . Should I use procedure? How do I use procedure?

    Hey Aaron!

    Change your FORM to FROM.

    using (SqlConnection con = new SqlConnection(WF_AbsPres.Properties.Settings.Default.DbConnectionString))
    {
       con.Open();
       SqlCommand command2 = new SqlCommand("DELETE FROM DevInOut where Cardserial=@Cardserial", con);
       commdand2.Parameters.AddWithValue("@Cardserial", textBox5.Text);
       command2.ExecuteNonQuery();
       con.Close();
    }
