Passing connection string to Enterprise Library DAAB 3.1 RRS feed

  • Question

  • User-1774624993 posted

    The company I work is considering to use the Enterprise Library Data Access Application Block. The problem is an internal policy that forces all company systems to get the connection string from a sql server.

    Is there any way to just pass the connection string to the Data Access Application Block instead of getting it from the app.config or web.config?

    I dont see any overloaded methods on the DatabaseFactory.CreateDatabase() method. Pointers please!

    You can write your own wrapper class to provide the CreateDatabase in this way by passing in the connection strings to the GenericDatabase() in DAAB:

    public static Database CreateDatabase(string server, string db, string id, string password, bool integratedSecurity, string dbProviderFactory)
    string connectionString = string.Format("Server={0};Database={1};Integrated Security={2};UID={3};PWD={4}", server, db, integratedSecurity, id, password);
    return new GenericDatabase(connectionString, dbProviderFactory); // dbProviderFactory = System.Data.SqlClient

    It works for me.

     If you know that it's definitely an SQL database being used, you can just create a new SqlDatabase rather than GenericDatabase.  Worked for me!


     Database _db = new SqlDatabase(connectionString);

    string dbFactory= "System.Data.SqlClient"

            db = New GenericDatabase(connectionString, DbProviderFactories.GetFactory(dbFactory))
