关于C#：如何将”Monday”转换为整数1，将”Tuesday”转换为2，等等，一直转换到星期五？

How do i convert “Monday” to the integer 1 and “Tuesday” to 2 etc all the way to friday?

本问题已经有最佳答案，请猛点这里访问。

我让一个用户输入一天(星期一)和一周的数字，以便在数组中搜索值。但是，要获得数组输出，我需要行和列的编号。行数可以从用户输入中获得，1，2等。但是，他们输入星期一，星期二等的部分比较复杂。是否有一种方法可以将星期一、星期二等转换为整数(1、2)，以便使用它查找数组元素？

我试过这个方法，但没用。将值转换为int显然不起作用，因为"monday"不是一个数字。有没有其他方法可以做到这一点？

int Value = Convert.ToInt32(value);

DateTime ClockInfoFromSystem = DateTime.Now;
Value = (int)ClockInfoFromSystem.DayOfWeek;

如果需要，这是代码的其余部分
