什么是指向一个静态方法在非静态类？ [英] What is the point to a static method in a non-static class?

问题描述

我听不太懂用下面的代码的根本错误：

I have trouble understanding the underlying errors with the code below:

class myClass
{
    public void print(string mess)
    {
        Console.WriteLine(mess);
    }
}

class myOtherClass
{
    public static void print(string mess)
    {
        Console.WriteLine(mess);
    }
}

public static class Test
{
    public static void Main()
    {
        myClass mc = new myClass();
        mc.print("hello");

        myOtherClass moc = new myOtherClass();
        moc.print("vhhhat?"); 
       //This says I can't access static method in non static context, but am I not?

    }
}

我不能想到的一个原因，人们会在非静态类声明一个静态方法，那么，为什么将.NET不会抛出异常错误。

I can't ever think of a reason why one would declare a static method in a non-static class, so why will .NET not throw an exception error.

此外，

moc.print("vhhhat?");

这会说我不能访问非静态的情况下，但试验与主静态方法是静态的，是什么参考？

This will say I can't access static method in non static context but Test and main are static, what is it referring to ?

推荐答案

一个静态类意味着你不能在非静态环境中使用它，这意味着你不能有类的对象的实例化和调用该方法。如果你想用你的打印方法，你必须做的：

A static class means that you cannot use it in a non-static context, meaning that you cannot have an object instantiation of that class and call the method. If you wanted to use your print method you would have to do:

myOtherClass.print("vhhhat?");

这不是一成不变的，当你创建了一个名为 MOC类的一个实例：

This is not static, as you created an instantiation of the class called moc:

myOtherClass moc = new myOtherClass();
