具有特殊字符的 C# 变量名

Question

我想在 C# 中的 string 变量名中包含一些特殊字符。

示例:string foo-bar = String.Empty;

据我所知，我不能像在上面的例子中提到的那样声明一个变量。有没有办法声明一个包含“-”的变量名？

来自 MSDN :

You can't just choose any sequence of characters as a variable name. This isn't as worrying as it might sound, however, because you're still left with a very flexible naming system. The basic variable naming rules are as follows:

The first character of a variable name must be either a letter, an underscore character (_), or the at symbol (@). Subsequent characters may be letters, underscore characters, or numbers.
