非静态类中的静态方法有什么意义?

问题描述

我无法理解以下代码的潜在错误:

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?

    }
}

我想不出为什么要在非静态类中声明静态方法，那么为什么 .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?");

这会说我无法在非静态上下文中访问静态方法，但 Test 和 main 是静态的，它指的是什么?

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

静态类意味着您不能在非静态上下文中使用它，这意味着您不能拥有该类的对象实例化并调用该方法.如果您想使用打印方法，则必须执行以下操作:

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?");

这不是静态的，因为您创建了一个名为 moc 的类的实例:

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

myOtherClass moc = new myOtherClass();
