Question

I have two repository classes below,
MoneyTransferRepository class is used by other classes in my project. I have designed it this way – is it right? If not, what is the best way?

Thanks

public interface IMoneyTransferRepository
{
    void UpdateBalance();
}

public interface IOrderRepository
{
    void Checkout();
    void SaveOrder();
}

public class MoneyTransferRepository : IMoneyTransferRepository
{
    DBDataContext DB;

    public MoneyTransferRepository(IDbConnection connection)
    {
        DB = new DBDataContext(connection);
    }

    public void UpdateBalance()
    {
        //do something DB.Table1.Update
    }

}


public class OrderRepository : IOrderRepository,IMoneyTransferRepository
{

    DBDataContext DB;
    IMoneyTransferRepository moneyTransferRepository;

    public OrderRepository()
    {
        DB = new DBDataContext();
        moneyTransferRepository = new MoneyTransferRepository(DB.Connection);
    }

    public void Checkout()
    {
        TransactionOptions transactionOptions = new TransactionOptions();
        transactionOptions.IsolationLevel = System.Transactions.IsolationLevel.ReadUncommitted;

        using (TransactionScope transactionScope = new TransactionScope(TransactionScopeOption.Required, transactionOptions))
        {
            try
            {
                UpdateBalance();
                SaveOrder();
                transactionScope.Complete();
            }
            catch
            {

            }

        }
    }

    public void UpdateBalance()
    {
        moneyTransferRepository.UpdateBalance();
    }

    public void SaveOrder()
    {
        //do something DB.SaveOrder.Update ......
        //   DB.Updatestock .....

    }
}

Don’t do transaction management in Repository. Thats why you get confused.
