无法访问的代码 C#

Question

执行几个 c# 循环和 if 语句。在 for 循环中突出显示无法访问的代码。我不太清楚这 1 个。

        public bool checkTime()
    {

        // Read values back from Json file
        var serializedList = File.ReadAllText(@filePathTimes);

        // getting a list of LockTime objects
        List<LockTime> deserializedList = (List<LockTime>)JsonConvert.DeserializeObject(serializedList, typeof(List<LockTime>));

        if (deserializedList.Count != 0)
        {

                // Grab whatever data you want from this list to store somewhere, such as a list of all Start and End integers.
                List<DateTime> intStartList = deserializedList.Select(entry => entry.Start).ToList();
                List<DateTime> intEndList = deserializedList.Select(entry => entry.End).ToList();

                //Then I do a foreach loop to go through every value in the start list and add the same located value to my listOfTimes (the list of LockTime objects with start and end)
                for (int x = 0; x < intStartList.Count; x++)
                {
                    TimeSpan start = new TimeSpan(intStartList[x].Hour, intStartList[x].Minute, intStartList[x].Second);
                    TimeSpan end = new TimeSpan(intEndList[x].Hour, intEndList[x].Minute, intEndList[x].Second);
                    TimeSpan now = DateTime.Now.TimeOfDay;
                    LockTime theTime = new LockTime(intStartList[x], intEndList[x]);
                    _lockTimes.Add(theTime);
                    if((now > start) && (now < end))
                    {
                        return true;
                    }

                        return false;

                }
        }
        return false;
    }

无法访问代码的亮点出现在 for 循环的 x++ 上。任何想法为什么会这样？

Answer 1

这是因为无论发生什么，循环内的代码都会执行return true; 或return false;。

循环不会循环。

Answer 2

原因是因为你在调用：

return true

或

return false

在循环中，所以它会总是在循环一次后退出。
