如何在 C# 中的多个上下文中使用 class 的单个实例？

Question

I'm trying to write a console RPG game in C#. I have a Party class containing a list of Heroes, PlayerTeam . I instantiate the Party class PlayerTeam in my static void Main(string[] args , and I am trying to write a new function creating an encounter with an enemy. However, when I try to reference the Party class instantiated in the Main function, I am thrown an error stating The name 'PlayerTeam' does not exist in the current context. Any help is appreciated.

Answer 1

Welcome! Since a Main method is always static, any non-local variables referenced in the Main method must also be static. Mark your PlayerTeam variable as static.

// change this:
// public Party PlayerTream
// to this:
public static Party PlayerTeam;

Longer term, you will want to create some sort of Game object and have it create all of your state, rather than having static variables all over the place.

Answer 2

You need to move the declaration of PlayerTeam from inside your Main() method out to CLASS level so that it is accessible from anywhere:

public static Party PlayerTeam;

public static void Main(string[] args)
{
    PlayerTeam = new Party();

}
