Console.WriteLine(DateTime.Now.ToString("hh:mm:ss"))
获取单个变量的值
Dim h As Integer = DateTime.Now.Hour '时
Dim m As Integer = DateTime.Now.Minute '分
Dim s As Integer = DateTime.Now.Second '秒
将datePicker设置为该日期，这样就可以确保每次从nib中加载此视图时，选取器都会重置为当前得日期和时间就可以了。
Dim ThisDay As String = Format(Now, "yyyy-MM-dd") '获得当前日期字符串
Dim ThisDateTime As DateTime = Convert.ToDateTime(ThisDay) '当前日期转换成DateTime
Dim ThisWeekDay As Integer = ThisDateTime.DayOfWeek '获得当前日期是星期几
Dim differadd As Integer = 1 - ThisWeekDay '相差的天数（星期1与当前星期几相差的天数）
Dim MyAdd As New TimeSpan(differadd, 0, 0, 0)
Dim MyYear As Integer = Format(Now, "yyyy") '获取当前日期的年份
Dim MyMonth As Integer = Format(Now, "MM") '获取当前日期的月份
Dim MyDay As Integer = Format(Now, "dd") '获取当前日期是几号
Dim MyToday As DateTime = New DateTime(MyYear, MyMonth, MyDay)
Dim Yourday As DateTime = MyToday.Add(MyAdd)
MsgBox("本周星期一的日期是：" Yourday)
一楼风中的奶牛的做法很棒，建议楼主采纳他的回答。
只是其中有一个Bug，就是“倒数第二次累计分钟数为59，累计秒数达到60的时候，会出现**:60:**”。例如{"10:57:35", "2:02:51"}，我这里做了修改，供参考。
另外，AddByInts中不需要进行循环和Select判断，可以简化。
同时，为了说明类和结构的关系，这里改用类。
也请一楼风中的奶牛勿怪罪在下啊！

不是 有 函数嘛？
now() 就是 吧
取得 后 再 分离出你所需的，分别赋值 就行了，当然 还是 有 函数的
