Question

我在允许/禁止活动的那一天有时间范围。我准备了一个小班，可以保持一天的时间范围。类的OkNok方法查找适用的句点并返回allow / forbidden。

我的问题：

如何使用<T>代替<bool> 将其设为通用。例如，它可以返回包含2个布尔值和a的类或结构值。

如果在路上可以加快速度和/或便于数据录入。

在下面的示例中，如果t1-t2之间的时间，则返回true 。介于t2-t3 false 之间，t3-t4 true 之间，以及t4 false 之后。

class Program { static void Main(string[] args) { TimeSpan t1 = new TimeSpan(8, 48, 0); TimeSpan t2 = new TimeSpan(9, 56, 0); TimeSpan t3 = new TimeSpan(10, 5, 0); TimeSpan t4 = new TimeSpan(13, 30, 0); TO TO = new TO { Ti = t1, Ok = true, NT = new TO { Ti = t2, Ok = false, NT = new TO { Ti = t3, Ok = true, NT = new TO { Ti = t4, Ok = false } } } }; Console.WriteLine("The time now is considered " + TO.OkNok(DateTime.Now)); Console.ReadLine(); } } public class TO { public TimeSpan Ti; public bool Ok; public TO NT; public bool OkNok(DateTime Time) { return OkNok(Time.TimeOfDay); } public bool OkNok(TimeSpan currentTime) { if (NT == null) return Ok; else if (currentTime > Ti && currentTime <= NT.Ti) return (Ok); else return (NT.OkNok(currentTime)); } }

您的问题不是很清楚，但我希望这有助于您：

//1) I want this class to be able to hold not just a true/false status, but a generic type T, so that it can return more data...
//2) If on the way it's possible to write it in a way that it would run faster and/or facilitate easier data entry.

class Program {
    static void Main(string[] args) {
        TimeSpan t1 = new TimeSpan(8, 48, 0);
        TimeSpan t2 = new TimeSpan(9, 56, 0);
        TimeSpan t3 = new TimeSpan(10, 5, 0);
        TimeSpan t4 = new TimeSpan(13, 30, 0);
        TO<bool> TO = new TO<bool>(t1, true) {
            new TO<bool>(t2, false) {
                new TO<bool> (t3, true) {
                    new TO<bool>(t4, false)
                }
            }
        };
        Console.WriteLine("The time now is considered " + TO.OkNok(DateTime.Now));
        Console.ReadLine();
    }
}

public class TO<T> : IEnumerable<TO<T>> {
    public TimeSpan Ti;
    public T Ok;
    public TO<T> NT;

    public TO(TimeSpan timeSpan, T ok) {
        this.Ti = timeSpan;
        this.Ok = ok;
    }

    public T OkNok(DateTime Time) {
        return OkNok(Time.TimeOfDay);
    }

    public T OkNok(TimeSpan currentTime) {
        if(NT == null) {
            return Ok;
        }
        if(currentTime > Ti && currentTime <= NT.Ti) {
            return Ok;
        }
        return NT.OkNok(currentTime);
    }

    public void Add(TO<T> nt) {
        this.NT = nt;
    }

    IEnumerator<TO<T>> IEnumerable<TO<T>>.GetEnumerator() {
        yield return this;
        if(NT != null) {
            yield return NT;
        }
    }

    System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator() {
        yield return this;
        if(NT != null) {
            yield return NT;
        }
    }
}

返回true false或某些数据当Time落在时间范围链中的时间范围内时？
