You can simply calculate the difference using the following method:
您可以使用以下方法简单地计算差异：
DateTime a = ;//some datetime
DateTime now = DateTime.Now;
TimeSpan ts = now-a;
int days = Math.Abs(ts.Days);

Simply subtract two DateTimes from each other, into a TimeSpan, and get the TotalDayscomponent from it.
简单地将两个DateTimes相减，变成 a TimeSpan，然后从中获取TotalDays组件。
TimeSpan diff = DateTime.Now - OtherDateTime
int days = (int)Math.Abs(Math.Round(diff.TotalDays));
It is rounded to remove the fraction caused by the hours/minutes/seconds, and the absolute value is given so you get the exact change.
它被四舍五入以去除由小时/分钟/秒引起的分数，并给出绝对值以便您获得确切的变化。

In Linq2Object:
在Linq2Object 中：
DateTime.Now.Subtract(yourDateTime).TotalDays
In Linq2Entites:
在Linq2Entites 中：
EntityFunctions.DiffDays(DateTime.Now, yourDateTime)
