A custom datetime struct
I am trying to develop a clock application with images for each digits from 0-9. Wrote a struct that gives me each digits every now and then. Following is the struct.
public struct TimeStruct
{
public DateTime dt
{
get
{
return DateTime.Now;
}
}
public int s
{
get
{
return 开发者_如何转开发dt.Second;
}
}
public int s2
{
get
{
return s % 10;
}
}
public int s1
{
get
{
return s / 10;
}
}
public int m
{
get
{
return dt.Minute;
}
}
public int m2
{
get
{
return m % 10;
}
}
public int m1
{
get
{
return m / 10;
}
}
public int h
{
get
{
return dt.Hour;
}
}
public int h2
{
get
{
return h % 10;
}
}
public int h1
{
get
{
return h / 10;
}
}
public int d
{
get
{
return (int)dt.DayOfWeek;
}
}
}
Please guide me to modify this struct so that the prop s2 should be set only when s1 becomes 0. And the same with minutes. Technology Used : Silverlight Platform : Windows Phone 7
Was that a bad idea to use struct?
What do you mean by "prop s2 should be set only when s1 becomes 0" - what do you want it to do when s1 isn't 0? Are you perhaps looking for nullable value types, where s1 would return the null value in some cases?
I have to say, I think this is a pretty confusing type. It has no real state - it's effectively just a bunch of static properties. Any reason for not implementing it as a bunch of static properties, e.g. in a CurrentDateTime
class? Or just use DateTime.Now
? Note that if you ask your struct for a bunch of values, one at a time, it may very well give you inconsistent results as time will pass. For example, suppose the time is 1:59:59 and you call s
, then m
, then h
- you may end up getting 59, 59, 2 as the current time rolls over from 1:59:59 to 2:00:00 between the last two calls. If you take the value of DateTime.Now
just once and ask it for all its properties, you'll get a consistent view.
Why re-invent the wheel ? Use DateTime
and TimeSpan
.
