I am having a situation where i need multiple connection strings to process a request, but i am not able to implement this using the Microsoft enterprise library.

somebody please tell me how can i set the connection string dynamically.

Answer 1

AFAIK, Its not possible to set the connection string dynamically, however you can write a Custom database factory to create a database with dynamic connection string

    public static class CustomDatabaseFactory
    {
        static readonly DbProviderFactory dbProviderFactory = DbProviderFactories.GetFactory("System.Data.SqlClient");

        public static Database CreateDatabase(string connectionString)
        {
            return new GenericDatabase(connectionString, dbProviderFactory);
        }
    }

and instead of calling this

Database db = DatabaseFactory.CreateDatabase();

call this method

Database db = CustomDatabaseFactory.CreateDatabase(connstring);

worked well for me!
