How do I get number of ticks per second of DateTime.UtcNow and convert it to a String value?
BAD QUESTION: try again Get ten millionths of a second
回答1:
A particular value of DateTime doesn't have a "ticks per second" associated with it; ticks are ticks no matter which DateTime they're in. Ticks are 100 nanoseconds long, so there are 10,000,000 of them per second.
Now to get that as a string is as simple as the string literal "10000000"... although in general you would obtain a number and just call ToString() on it. For instance, you could use:
string ticksPerSecond = TimeSpan.TicksPerSecond.ToString();
Your question is a slightly odd one, so I wonder whether we're missing something... could you edit the question with more details about what you're trying to do. For example, are you trying to determine the number of ticks within the particular second of a particular DateTime? That's most easily done as:
long ticks = dt.Ticks % TimeSpan.TicksPerSecond;
回答2:
You find the ticks per second as a constant on TimeSpan:
TimeSpan.TicksPerSecond
Not sure what you are trying to do though...
(DateTime.UtcNow.Ticks / TimeSpan.TicksPerSecond).ToString() // Total number of seconds...
回答3:
I think you may want TimeSpan.TicksPerSecond.
Console.WriteLine("tps = {0}", TimeSpan.TicksPerSecond.ToString());
回答4:
The number of ticks per second in a DateTime value is always 10000000. One tick is 100 nanoseconds.
So, if you want to convert that to a string:
10000000.ToString()
