通过嵌套类不能访问外部类的非静态成员

问题描述：

我有误差

无法访问Project.Neuro外类型的非静态成员通过
嵌套式Project.Neuro.Net

Cannot access a non-static member of outer type 'Project.Neuro' via nested type 'Project.Neuro.Net'

与code像这样（简体）：

with code like this (simplified):

class Neuro
{
    public class Net
    {
        public void SomeMethod()
        {
            int x = OtherMethod(); // error is here
        }
    }

    public int OtherMethod() // its outside Neuro.Net class
    {
        return 123;  
    }
}

我可以将有问题的方法Neuro.Net类，但我需要外界的这种方法。

I can move problematic method to Neuro.Net class, but I need this method outside.

林样的目标规划新手。

先谢谢了。

答

问题是，嵌套的类不是的导出的类，所以在外部类中的方法不是的继承的

The problem is that nested classes are not derived classes, so the methods in the outer class are not inherited.

某些选项

请方法静态：

class Neuro
{
    public class Net
    {
        public void SomeMethod()
        {
            int x = Neuro.OtherMethod(); 
        }
    }

    public static int OtherMethod() 
    {
        return 123;  
    }
}

使用继承代替嵌套类：

Use inheritance instead of nesting classes:

public class Neuro  // Neuro has to be public in order to have a public class inherit from it.
{
    public static int OtherMethod() 
    {
        return 123;  
    }
}

public class Net : Neuro
{
    public void SomeMethod()
    {
        int x = OtherMethod(); 
    }
}

创建神经的一个实例：

class Neuro
{
    public class Net
    {
        public void SomeMethod()
        {
            Neuro n = new Neuro();
            int x = n.OtherMethod(); 
        }
    }

    public int OtherMethod() 
    {
        return 123;  
    }
}
