Is that right
Can someone solve my problem

internal class lianjie
{
// In order to make the program beautiful , Create multiple classes to connect to the database
public SqlConnection connet()// Create a class named connet Class
{

        string conStr = @"Data Source=LAPTOP-JA2J1QNT;Initial Catalog=bookmanagement;Integrated Security=SSPI";            SqlConnection sc=new SqlConnection(conStr);        sc.Open();        return sc;    }

Take the answer ：

Wrong connection string . No account password None .
internal Don't use Since you encapsulate Make links use public Unlimited access
Score
