如何增加一天的额外时间

问题描述

你好朋友我有这个问题

hello frens i have this problem

DateTime arrtime = DateTime.Parse(txtarrivaltime.Text);
DateTime endTime = DateTime.Now;

TimeSpan span1 = endTime.Subtract(arrtime);
TimeSpan span2 = span1.Duration();

string NumOfDays = span1.Days;


string Shours = span2.Hours.ToString()+ ?;

现在我要动态增加小时数，即24 *一些值，例如24 * 1或24 * 2或...如果NumOfDays大于0，则以小时为单位.
请提供代码

now i want to dynamically add hours i.e. 24* some value like 24*1 or 24*2 or ... in Shours if the NumOfDays is more than 0. how can i do this dynamically?
please provide with the code

推荐答案

// add 1 day to the current date time
DateTime dt = DateTime.Now.AddDays(1);

DateTime arrtime = DateTime.Parse("txtarrivaltime.Text");
DateTime endTime = DateTime.Now;

TimeSpan span1 = endTime.Subtract(arrtime);
TimeSpan span2 = span1.Duration();

int NumOfDays = span1.Days;

TimeSpan span3 = new TimeSpan(24 * NumOfDays, 0, 0);
TimeSpan span4 = span2.Add(span3);
string Shours = span4.TotalHours.ToString();

(这是故意散布的，因此您可以更好地看到步骤)
