c# - 检查时间是否在一个范围内

Question

我试图执行检查是在指定的时间间隔内输入时间，但我卡住了......我有一个主块和另一个执行检查的类是间隔内输入的时间，但我不断收到“方法'IsBetween'没有过载接受 0 个参数”当我尝试调用该方法并获得简单的布尔值真或假时，我知道解决方案可能真的很简单，但我就是想不通......：

 static void Main()
    {
        var currentTime = Console.ReadLine();
        DateTime now = Convert.ToDateTime(currentTime);
        var dateNow = DateTime.Now;
        var startTime = new DateTime(dateNow.Year, dateNow.Month, dateNow.Day, 13, 0, 0);
        var endTime = new DateTime(dateNow.Year, dateNow.Month, dateNow.Day, 3, 0, 0);
    }

这是我的检查课：

public static class TimeExtensions
{
    public static bool IsBetween(this DateTime now, DateTime startTime, DateTime endTime)
    {
        if (now.TimeOfDay == startTime.TimeOfDay) return true;
        if (now.TimeOfDay == endTime.TimeOfDay) return true;

        if (startTime.TimeOfDay <= endTime.TimeOfDay)
            return (now.TimeOfDay >= startTime.TimeOfDay && now.TimeOfDay <= endTime.TimeOfDay);
        else
            return !(now.TimeOfDay >= endTime.TimeOfDay && now.TimeOfDay <= startTime.TimeOfDay);
    }
}

Answer 1

该错误表明您正在调用IsBetween：

bool b = now.IsBetween();

但您需要提供开始和结束时间：

bool b = now.IsBetween(startTime, endTime);
