Global variables in Visual C#
提问by neuromancer
How do I declare global variables in Visual C#?
如何在 Visual C# 中声明全局变量？
采纳答案by Bob
How about this
这个怎么样
public static class Globals {
public static int GlobalInt { get; set; }
}
Just be aware this isn't thread safe. Access like Globals.GlobalInt
请注意这不是线程安全的。访问喜欢Globals.GlobalInt
This is probably another discussion, but in general globals aren't really needed in traditional OO development. I would take a step back and look at why you think you need a global variable. There might be a better design.
这可能是另一个讨论，但一般来说，传统 OO 开发中并不真正需要全局变量。我会退后一步，看看为什么你认为你需要一个全局变量。可能会有更好的设计。

Use the const keyword:
使用 const 关键字：
public const int MAXIMUM_CACHE_SIZE = 100;
Put it in a static class eg
把它放在一个静态类中，例如
public class Globals
{
public const int MAXIMUM_CACHE_SIZE = 100;
}
And you have a global variable class :)
而且你有一个全局变量类:)

The nearest you can do this in C# is to declare a public variable in a public static class. But even then, you have to ensure the namespace is imported, and you specify the class name when using it.
在 C# 中最接近的方法是在公共静态类中声明一个公共变量。但即便如此，您也必须确保导入命名空间，并在使用时指定类名。

A public static field is probably the closest you will get to a global variable
公共静态字段可能是最接近全局变量的字段
public static class Globals
{
public static int MyGlobalVar = 42;
}
However, you should try to avoid using global variables as much as possible as it will complicate your program and make things like automated testing harder to achieve.
但是，您应该尽量避免使用全局变量，因为它会使您的程序复杂化并使诸如自动化测试之类的事情更难以实现。
