编写可复用的C#时间差计算函数

using System;

public class TimeDifferenceCalculator
{
    public TimeSpan CalculateTimeDifference(DateTime startTime, DateTime endTime)
    {
        return endTime - startTime;
    }
}

使用示例：

TimeDifferenceCalculator calculator = new TimeDifferenceCalculator();
DateTime startTime = new DateTime(2022, 1, 1, 12, 0, 0);
DateTime endTime = new DateTime(2022, 1, 1, 14, 30, 0);
TimeSpan difference = calculator.CalculateTimeDifference(startTime, endTime);
Console.WriteLine("Time difference: " + difference);
