How Can I Efficiently Check if a Date Falls Within a Range Using C# DateTime?

Checking Date Range with DateTime in C#

When determining if a specific date falls within a predefined range, it's crucial to consider efficient approaches. While direct comparison may seem obvious, let's explore a leaner solution.

Simple Comparison

The following code utilizes simple comparison to assess if a given date, dateToCheck, lies between two dates, startDate and endDate:

return dateToCheck >= startDate && dateToCheck < endDate;

Considerations

However, it's important to keep in mind that:

• Time Zones: DateTime can represent different time zones, so ensure consistency.
• Inclusivity: Determine if start and end points should be inclusive or exclusive. The code above treats the lower bound as inclusive and the upper bound as exclusive.
