When I try to connect server by setting value through a string v

Answer 1

Maybe the server name and the database name (in the dbname and catname variables) are just wrong?

BTW, i would recommend using the SqlConnectionStringBuilder class.

var sb = new SqlConnectionStringBuilder() { InitialCatalog = catname,
                                            DataSource = dbname,
                                            UserID = "sa",
                                            Password = "sa" };

var dbConnection = new SqlConnection(sb.ConnectionString);
