Is there BETWEEN DateTime in C# just like SQL does?

Question

Is there between DateTime in C# ? I know I can do simple check with if (a > date1 && a < date2) but I was trying to find Between meth

Answer 1

Why restrict to just dates, use the IComparable interface.

public static bool InclusiveBetween (this IComparable a, IComparable b, IComparable c)
{
    return a.CompareTo(b) >= 0 && a.CompareTo(c) <= 0;
}

public static bool ExclusiveBetween (this IComparable a, IComparable b, IComparable c)
{
    return a.CompareTo(b) > 0 && a.CompareTo(c) < 0;
}

public static bool SqlBetween (this IComparable a, IComparable b, IComparable c)
{
    return a.InclusiveBetween(b, c);
}

Answer 2

I use something similar to Richard Schneider's (universal between) and Gary Pendlebury's answer (simpler configurable boundary inclusion)

public static bool Between(this IComparable value, IComparable lowerBoundary, IComparable upperBoundary, 
    bool includeLowerBoundary=true, bool includeUpperBoundary=true)
{
    var lower = value.CompareTo(lowerBoundary);
    var upper = value.CompareTo(upperBoundary);
    return (lower > 0 || (includeLowerBoundary && lower == 0)) &&
           (upper < 0 || (includeUpperBoundary && upper == 0));
}

Answer 3

There is not, but if you obey number line formatting per Code Complete, the raw code looks simpler:

if((lowDate < a) && (a < highDate)) 

Answer 4

You can add an extension method :

public static Boolean Between(this DateTime input, DateTime minDate, DateTime maxDate)
{
    // SQL takes limit in !
    return input >= minDate && input <= maxDate;
}

Answer 5

There is not a Between function but should be easy enough to add one

public static bool Between(DateTime input, DateTime date1, DateTime date2)
{
    return (input > date1 && input < date2);
}

Answer 6

No, there is not.
