在以下的<代码>中,该编码始终适用。
DateTime d = DateTime.Now;
bool thisIsAlwaysTrue = d == d;
但是,时间确实是这样。 现在的工作方式就是: 真的保证是真实的? 或者,提及现在财产之间的锁定变化吗?
bool isThisAlwaysTrue = DateTime.Now == DateTime.Now;

锁定可以在两个接连电话到日期之间改变。 现在:
日期。 如今,财产变幻莫测,也就是说,这无疑会改变用途。 但是,你赋予它的变量并非不稳定。
因此,这应当永远产生以下结果:
DateTime d = DateTime.Now;
bool result = d == d;
它按时间分配退还的价值。 现在是变数,而不是财产本身。 因此,该法典将永远平等。
但是,这并不总是真正的结果:
bool result = DateTime.Now == DateTime.Now;
我必须建议你努力这样做。 该法典在单元中只占第二部分:
using System;
class Program {
static void Main(string[] args) {
while (DateTime.UtcNow == DateTime.UtcNow) ;
Console.WriteLine("oops");
Console.ReadLine();
}
}
我相信,它将会恢复。
时间是不可改变的,因此一旦分配,时间就永远不会改变。 您对日期的呼吁。 现在就没有“联系”——它只是分配了什么<>? 日期: 现在需要的是变数(d)——它不会给出某种参考。
因此,如果出现这样的拖延:
DateTime d = DateTime.Now; // Let s assume it s 9:05:10
Thread.Sleep(100);
Console.WriteLine(d); // will still be 9:05:10, even though it s much later now
