C＃对象引用是必需的问题

本文介绍了C＃对象引用是必需的问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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);
