C# 中的时间跨度总和

时间跨度总和：C# 中处理时间的强大工具

csharp
DateTime start = new DateTime(2021, 1, 1);
DateTime end = new DateTime(2021, 12, 31);
TimeSpan difference = end - start;
int days = difference.Days;
Console.WriteLine("两个日期之间的天数差为：" + days);

csharp
DateTime current = DateTime.Now;
TimeSpan interval = TimeSpan.FromDays(7);
DateTime nextWeek = current + interval;
DateTime previousWeek = current - interval;
Console.WriteLine("当前时间：" + current);
Console.WriteLine("下一周时间：" + nextWeek);
Console.WriteLine("上一周时间：" + previousWeek);
