问题描述
我有很多字符串，我想通过switch语句运行。这些字符串是诸如无之类的术语。或者未定义，我想设置为Null。我的第一个想法是创建一个数组，然后使用foreach语句通过switch语句运行每个字符串。这里显而易见的问题是你不能分配给迭代变量。我怎样才能解决这个问题？
I have numerous strings that I would like to run though a switch statement. These strings are terms such as "None" or "Undefined", that I would like to set to Null. My first thought was to create an array and then use a foreach statement to run each string through the switch statement. The obvious problem here is that you cannot assign to the iteration variables. How can I get around this?
推荐答案
我想我不明白如何解决分配给字符串的问题。
I suppose I do not understand how that solves the problem of assigning to the strings.
创建一个列表/数组，但使用for循环而不是foreach。然后你就可以为你的字符串赋值了。
Create a list/array but use a for loop instead of a foreach. Then you will be able to assign values to your strings.
