C# - Find if current time falls in a time range

Question

Using .NET 3.5

I want to determine if the current time falls in a time range.

So far I have the currentime:

DateTime currentTime = new DateTime();
currentTime.TimeOfDay;

I'm blanking out on how to get the time range converted and compared. Would this work?

if (Convert.ToDateTime("11:59") <= currentTime.TimeOfDay 
    && Convert.ToDateTime("13:01") >= currentTime.TimeOfDay)
{
   //match found
}

UPDATE1: Thanks everyone for your suggestions. I wasn't familiar with the TimeSpan function.

Answer 1

if (new TimeSpan(11,59,0) <= currentTime.TimeOfDay && new TimeSpan(13,01,0) >=  currentTime.TimeOfDay)
{
   //match found
}

if you really want to parse a string into a TimeSpan, then you can use:

    TimeSpan start = TimeSpan.Parse("11:59");
    TimeSpan end = TimeSpan.Parse("13:01");

Answer 2

For checking for a time of day use:

TimeSpan start = new TimeSpan(10, 0, 0); //10 o'clock
TimeSpan end = new TimeSpan(12, 0, 0); //12 o'clock
TimeSpan now = DateTime.Now.TimeOfDay;

if ((now > start) && (now < end))
{
   //match found
}

For absolute times use:

DateTime start = new DateTime(2009, 12, 9, 10, 0, 0)); //10 o'clock
DateTime end = new DateTime(2009, 12, 10, 12, 0, 0)); //12 o'clock
DateTime now = DateTime.Now;

if ((now > start) && (now < end))
{
   //match found
}

Answer 3

You're very close, the problem is you're comparing a DateTime to a TimeOfDay. What you need to do is add the .TimeOfDay property to the end of your Convert.ToDateTime() functions.

Answer 4

The TimeOfDay property returns a TimeSpan value.

Try the following code:

TimeSpan time = DateTime.Now.TimeOfDay;

if (time > new TimeSpan(11, 59, 00)        //Hours, Minutes, Seconds
 && time < new TimeSpan(13, 01, 00)) {
    //match found
}

Also, new DateTime() is the same as DateTime.MinValue and will always be equal to 1/1/0001 12:00:00 AM. (Value types cannot have non-empty default values) You want to use DateTime.Now.

Answer 5

Try using the TimeRange object in C# to complete your goal.

TimeRange timeRange = new TimeRange();
timeRange = TimeRange.Parse("13:00-14:00");

bool IsNowInTheRange = timeRange.IsIn(DateTime.Now.TimeOfDay);
Console.Write(IsNowInTheRange);

Here is where I got that example of using TimeRange
