推荐答案

添加任意时间跨度并不总能达到目标。你能做的最好的事情是检测它何时更大。类似于：

Adding an arbitrary time span wouldn't always hit the target. The best you can do is detect when it is greater. Something like:

System.DateTime dt = System.DateTime.Now;
System.TimeSpan duration = new System.TimeSpan(0, 1, 5, 0);

int day = dt.Day;
while (dt.Day == day)
{
  Console.WriteLine(dt.ToString());
  dt = dt.Add(duration);
}
