在静态方法中调用公共方法时遇到麻烦 [英] Having trouble calling a public method in a static method

问题描述

我真的很抱歉，因为这可能是一个非常新奇的问题，但是我在任何地方都找不到答案. 我对如何调用下面的函数DoStuff感到困惑

I'm really sorry because this is probably a very newbish question, but I can't find an answer to this anywhere. I'm confused on how to call the function DoStuff below

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        public void DoStuff()
        {
            Console.WriteLine("I'm doing something...");
        }
        static void Main(string[] args)
        {
            DoStuff();
        }
    }
}

推荐答案

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        public static void DoStuff()
        {
            Console.WriteLine("I'm doing something...");
        }
        static void Main(string[] args)
        {
            DoStuff();
        }
    }
}

C#是一种面向对象的编程语言，这意味着类中的每个成员.由于静态方法是在普通方法之前初始化的，因此应将DoStuff定义为静态方法，以便可以在Main方法中调用它.创建类后，静态成员已经在计算机的内存中初始化，但是，非静态成员将等待该类的实例.在这种情况下，静态成员属于整个类，而非静态成员属于一个类的实例.因此，您可以使用ClassName.StaticMember调用StaticMember，并且需要一个类的真实实例才能调用non-staticMember.就像:如果DoStuff是非静态方法，则为new Program().DoStuff()

C# is an object oriented programming language which means that every member within a class. Since the static method init before normal method , you should define DoStuff as a static method so that it can be call within Main method. When the class has been created, the static member already init in the computer's memory, however, the non-static member will waiting to the instance of the class. In that case, the static member belong to the whole class and the non-static belong to an instance of a class. So you can use ClassName.StaticMember to call StaticMember and you need a real instance of a class to call non-staticMember. just like: new Program().DoStuff() if the DoStuff is non-static method
