如何使功能延迟5秒

我正在尝试将其转换为C#代码:

I'm trying to translate this into C# code:

等待5秒钟，然后从银行帐户中扣款.

Wait 5 seconds and then debit the bank account.

我有种感觉我快要走了……但是这没用.我这样做正确吗?

I've got a feeling I'm close... but this isn't working. Am I doing this the right way?

    public override void Process(BankAccount b, decimal amount)
    {
        DateTime present = DateTime.Now;
        DateTime addFiveSeconds = DateTime.Now.AddSeconds(5);

        if (present != addFiveSeconds)
        {
            this.Status = TransactionStatus.Pending;
        }
        else
        {
            b.Debit(amount);
            this.Status = TransactionStatus.Complete;
        }
    }
