ConnectionString loses password after connection.Open

Question

i\'m using ADO.NET to get some information from the database on a server,
so this is what i do:

string conStr = \"Data Source=myServer\\SQLEXPRESS;Initia         


        

Answer 1

Look in the connection string, in order to keep the password in the ConnectionString property you must add "Persist Security Info=true;" to the connection string itself.

The following example will strip the password out:

string conStr = "Data Source=localhost;Initial Catalog=MyDatabase;User Id=MyUser;Password=MyPassword";
SqlConnection conn = new SqlConnection(conStr);
conn.Open();
conn.Close();
Console.WriteLine(conn.ConnectionString);

The following example will keep the password in the conn.ConnectionString:

string conStr = "Persist Security Info=True;Data Source=localhost;Initial Catalog=MyDatabase;User Id=MyUser;Password=MyPassword";
SqlConnection conn = new SqlConnection(conStr);
conn.Open();
conn.Close();
Console.WriteLine(conn.ConnectionString);

Its a property set inside the connection string itself not in the SqlConnection object, I put it in the beginning of the connection string just so you don't have to scroll to see it, it can go anywhere in the connection string, I usually see it at the end.

Like others have said, if you need to do this you quite possibly are not using the SqlConnection object exactly as it was intended.
