c# – 是否可以将“var”作为全局变量

我注意到c#中的全局变量还有其他线程.例如整数,字符串等.

public static int;

但是我需要使用另一个线程没有提及的“var”

public static var;

似乎不起作用.

所以我要问的是在c#中可以将“var”作为全局变量吗？

解决方法

C# specification(第26.1节)内容如下：

[`var is] an implicitly typed local variable declaration …

它更进一步：

A local variable declarator in an implicitly typed local variable
declaration is subject to the following restrictions:

• The declarator must include an initializer.
• The initializer must be an expression.
• The initializer expression must have a compile-time type which cannot
  be the null type.
• The local variable declaration cannot include
  multiple declarators.
• The initializer cannot refer to the declared variable itself

所以不,你不能这样做.此外,我建议不要考虑全局变量.

语言不支持全局变量.您可以在公共静态字段中找到替代方法,但这会泄漏对象状态并破坏封装.
