在VS2010中添加DateTimePicker的小時數

Question

如何在VS中的DateTimePicker中添加3小時？

Dim dateAdd as Date = DateTimePicker1 

    dateAdd.AddHours(3) 

    MsgBox(dateAdd.Value.ToString) 

爲什麼它不會添加到我的系統中？

Answer 1

DateTime.AddHours()返回一個新的日期時間：

Dim dateAdd as Date = DateTimePicker1 

Dim newDate as Date = dateAdd.AddHours(3) 

MsgBox(newDate.Value.ToString)
