推荐答案

更好的解决方案:

Better solution:

TimeSpan ts = secondDate.Value - firstDate.Value;
myTextBox.Text = ts.Days.ToString();

如果仅使用DateTime.Day，则如果月份发生变化等，您将遇到问题.

If you just use DateTime.Day, then you will get problems if the month changes, etc.

尝试 x = DateTimePicker1.Value.Day - DateTimePicker2.Value.Day.

更好的解决方案是:
两天均为日期时间格式

System.TimeSpan span = ToDate-DateFrom;
int days =(int)span.TotalDays;

Better Solution is :
Both Days are in Date time Format

System.TimeSpan span = ToDate - DateFrom;
int days = (int)span.TotalDays;
