如何计算两日期相差的小时数？天数？

[brightheroes]

System.TimeSpan ts = dt1 - dt2;
ts.Days
ts.Hours

[yuzaichun]

DateTime oldDate = new DateTime(2002,7,15);
DateTime newDate = DateTime.Now;

// Difference in days, hours, and minutes.
TimeSpan ts = newDate - oldDate;
// Difference in days.
int differenceInDays = ts.Days;

[asam2183]

TimeSpan th=data1-data2;
th.Hours;

[radeonle]

TimeSpan th=D2-D1;
th.Days; 是天数
th.Hours;是小时数

利用System.TimeSpan的Hours属性。

[cublue]

DateTime oldDate = new DateTime(2002,7,15);
DateTime newDate = DateTime.Now;
TimeSpan ts = newDate - oldDate;
int Hours = ts.Hours;

[billqi]

TimeSpan.FromHours(DateTime.Compare(D1,D1)).Hours;

[piziliu2003]

DateTime t1 = new DateTime(2002,7,30);
DateTime t2 = new DateTime(2002,5,28);
TimeSpan diff=t1-t2;
MessageBox.Show(diff.Days.ToString());
MessageBox.Show(diff.hours.ToString());
這個形象點.
