内部类和外部类在C＃ [英] Inner class and Outer class in c#

问题描述

如何在C＃中实现内外部类

how to implement inner outer classes in c#

我有两个嵌套类

像

class Outer
{
    int TestVariable = 0;
    class Inner
    {
        int InnerTestVariable = TestVariable // Need to access the variable "TestVariable" here
    }
}

其示值误差在编译时。

它可以通过

1）使TestVariable静态

1) Making TestVariable as static

2）传递​​外部类的一个实例内部类

2) Passing an instance of Outer class to Inner class

而在的Java 就没有必要创建实例或静态的。

but in java there is no need to create Instance or static .

我可以使用C＃相同的功能呢？

can i use the same functionality in C# too ?

推荐答案

没有，C＃不具备在这种情况下，相同的语义的Java。你可以让 TestVariable 常量，静态，或通外的实例内蒙古构造因为你已经注意到。

No, C# does not have the same semantics as Java in this case. You can either make TestVariable const, static, or pass an instance of Outer to the constructor of Inner as you already noted.
