C# 错误集合访问器不可访问-扣除用户'；s分数作为货币

我有一个分数管理器，可以跟踪你的分数。有了这些要点，我希望用户能够为他的角色购买升级

但每次我试图访问用户的当前分数时，我都会收到相同的错误消息

如果您查看下面的Upgrademenu文档，您可以看到我正在尝试执行以下操作“//ScoreManager.Score-=upgradeCost；”，因为当我激活它时，会收到错误消息：//

无法在此上下文中使用属性或索引器“ScoreManager.Score”，因为集合访问器不可访问

如果类的set访问器设置为private，则不能从类外部为Score赋值。将其设置为

public

或在

ScoreManager

类上创建一个方法来执行扣减。

如果其Set访问器设置为private，则不能从类外部为分数赋值。将其设置为

public

或在

ScoreManager

类上创建一个方法来执行推断。

我理解这一点，但即使我将代码更改为“public static int Score{get；protected Set；}”，并尝试从其他文档访问它。我仍然收到相同的错误消息。@mafiaf

protected

不是

public

并且不起作用。我知道，通过删除整个“protected”部分，我不再收到错误消息。但是它似乎没有从scoreManager中扣除分数。@mafiaf这是一个单独的问题。我理解这一点，但即使我将代码更改为“public static int Score{get；protected set；}”，并尝试从另一个文档访问它。我仍然收到相同的错误消息。@mafiaf

protected

不是

public

并且不起作用。我知道，通过删除整个“protected”部分，我不再收到错误消息。但这似乎并没有从得分经理那里扣减分数。@mafiaf这是另一个问题。
