C＃：如何在for循环中为整数（i）分配许多变量？ [英] C#: How do i assign many variables with an integer(i) in for loop?

问题描述

想象一下，我们有5个字符串变量，我们希望在运行时为它们分配Foo。

Imagine we have 5 string variables and we want to assign "Foo" to them during runtime.

而不是这个

string a1 = "Foo";
string a2 = "Foo";
string a3 = "Foo";
string a4 = "Foo";
string a5 = "Foo";

我们不能使用这样的东西：

Can't we use something like this:

for(int i = 0;i < 5;i++)
{
    a+i = "Foo";
}

是否无法以类似的方式访问它们？

Is it impossible to access them in a similiar way?

推荐答案

正如其他人所说，数组（或其他集合）是一种更好的方法。

As others have said, an array (or another collection) is a much better way of doing this.

将数组视为仅通过索引始终访问的变量集合。

Think of an array as just being a collection of variables which you always access by index.

我不能想一想为什么你想要有一组变量，如你的问题所示。如果你绝对有这样做，并且它们是实例/静态变量，你可以使用反射来访问它们，如果你真的想要 - 但是使用数组或其他集合会更好，更好。

I can't think of any reason why you'd want to have a set of variables as shown in your question. If you absolutely have to do that, and they're instance/static variables, you could use reflection to access them if you really wanted to - but using an array or other collection would be much, much better.
