C＃对象引用是必需的问题 [英] C# an object reference is required problem

问题描述

在我的主程序中我试图使用

in my main program I am trying to use

stack.createStack(40);

堆栈类中的
我有这个功能

in stack class I have this function

public void createStack(object value)
       {
           stack S = new stack();
           head = new Node();
           head.Cont = value;
           size++;


       }

我只是想做一个构造函数将会创建一个新堆栈，堆栈定义如下：

I am just trying to make a constructor function which will creare a new stack, stack defined like this

<pre>public List<int> stacklist;
        public class Node
        {
            public object Cont;
            public Node Next;

        }
        public Node head;

        public stack()
        {
            head = null;
        }
        public stack(object value)
        {
            head = new Node();
            head.Cont = value;

        }

我收到错误：

I get the error:

Error	CS0120	An object reference is required for the non-static field, method, or property 'stack.createStack(object)'	Lists	

我试过的：



我不知道下一步该做什么或如何避免这个

What I have tried:

I have no idea what to do next or how to avoid this

推荐答案

尝试添加 static ，如下所示：

Try adding static like this :

public static void createStack(object value)
{
    stack S = new stack();
    head = new Node();
    head.Cont = value;
    size++;
}

或如果 static 不是您需要的，请按以下方式使用您的课程你的班级有州：

or using your class as follows if static is not what you need and your class has state :

var s = new stack();
s.createStack(40);
