C＃中的动态If语句

Question

我正在尝试使用https://github.com/dahall/TaskScheduler，并且有这种语法。

wt.DaysOfWeek = DaysOfTheWeek.Monday | DaysOfTheWeek.Saturday;

问题是我有一天的名单

List<String> days = {"Tuesday", "Thursday"}

我想动态地将列表变成'一条if语句'，这样结果是

wt.DaysOfWeek = DaysOfTheWeek.Tuesday | DaysOfTheWeek.Thursday;

到目前为止，我考虑循环列表，连接字符串并评估它（即使eval函数在C＃中本身并不存在）。

我该如何实现？谢谢吗？

尝试一下：

        List<String> days = new List<string> {"Tuesday", "Thursday"};

        DaysOfTheWeek? dow = null;

foreach (var day in days) {
        DaysOfTheWeek dayValue;
         if (Enum.TryParse(day, true, out dayValue)) {
             dow = dow == null ? dayValue : dow | dayValue;
         }
}
