使用 DateTime.Now 包括从今天开始的日期

Question

I have this code:

public void SetPublisherDatesNotAvailable(string strPublisher, DateTime[]listDatesNotAvailable)
{
    if (_PublisherData.PublisherDictionary.ContainsKey(strPublisher))
    {
        Publisher pPublisher = _PublisherData.PublisherDictionary[strPublisher];
        pPublisher.Availability.DatesNotAvailable =
            new List<DateTime>(listDatesNotAvailable.Where(d => d >= DateTime.Now)); // Ignore past dates

        _PublisherData.PublisherDictionary[strPublisher] = pPublisher;
    }
}

But it is failing to include any entry with todays date. It seems to be taking into account the TimeStamp too ? That would explain it. But I only want to exclude it if it was yesterdays date.

How do I fix this?

Thanks.

Answer 1

您可以使用DateTime.Now.Date来获取没有时间部分的值，或者更准确地说，将时间部分设置为午夜。

Answer 2

正如您在问题中提到的， d和DateTime.Now都将采用 TimeStamp，如果您想排除 TimeStamp 意味着您必须使用d.Date和DateTime.Today （这将为您提供没有 TimeStamp 的今天的日期，并且等于DateTime.Now.Date所以这一行listDatesNotAvailable.Where(d => d >= DateTime.Now)应该是这样的：

listDatesNotAvailable.Where(d => d.Date >= DateTime.Today)
