推荐答案

尝试阅读 C#中的访问修饰符 [点击率]

该代码实际上存在很多错误，但是... 1.使用属性作为变量的访问者，不应在定义变量的范围之外直接访问成员变量 2.使用适当的访问修饰符定义属性，以限制其可访问性.即私有，受保护，内部，公共等. 如果不是Google，希望可以助您一臂之力 c#访问修饰符 [ ^ ]了解更多信息 There''s actually quite a lot wrong with that code, however... 1. Use properties as accessors to variables, you should not be accessing member variables directly outside of the scope in which they''re defined 2. Define the property with the appropriate access modifier to scope it''s accessibility. i.e., private, protected, internal, public etc. Hopefully that''ll get you going, if not Google c# access modifier[^] for more information
