You need to define keywordsas public
你需要定义keywords为 public
public String[] keywords = { "abstract", "as", "etc." };
Currently it is privateand that is why not accessible outside the class.
目前是这样private，这就是为什么不能在课堂外访问的原因。
Access Modifiers (C# Programming Guide)
Class members, including nested classes and structs, can be public, protected internal, protected, internal, or private. The access level for class members and struct members, including nested classes and structs, is private by default.
类成员，包括嵌套类和结构，可以是 public、protected internal、protected、internal 或 private。类成员和结构成员（包括嵌套类和结构）的访问级别默认为私有。

Try to make the string-array public:
尝试公开字符串数组：
public class KeyWord
{
public String[] keywords = { "abstract", "as", "etc." };
}

You should make a property for Keywords as follows
您应该为关键字创建一个属性，如下所示
public String[] Keywords
{
get{return keywords;}
}
its a protection violation as variables are private by default
它违反保护，因为变量默认是私有的
回答by Herks
Use this code instead:
请改用此代码：
public class KeyWord
{
String[] keywords = { "abstract", "as", "etc." };
}
The protection level for variable is privateby default. A good practice is using property for members in class.
变量的保护级别是private默认的。一个好的做法是为类中的成员使用属性。

You need to define the your class with "public" keyword
您需要使用“public”关键字定义您的类
