How about this

public static class Globals {
    public static int GlobalInt { get; set; }
}

Just be aware this isn't thread safe. Access like 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.

A public static field is probably the closest you will get to a global variable

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.

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.

Use the const keyword:

public const int MAXIMUM_CACHE_SIZE = 100;

Put it in a static class eg

public class Globals
{
    public const int MAXIMUM_CACHE_SIZE = 100;
}

And you have a global variable class :)
