为什么覆盖在C＃alowed静态方法 [英] Why is overriding static method alowed in C#

问题描述

protected static new void WhyIsThisValidCode()
{
}

你为什么允许覆盖静态方法？
无非是错误可能来自它，它doensn't工作，你想。

Why are you allowed to override static methods? Nothing but bugs can come from it, it doensn't work as you would think.

看看下面的类。

class BaseLogger
{
    protected static string LogName { get { return null; } }

    public static void Log(string message) { Logger.Log(message, LogName); }
}

class SpecificLogger : BaseLogger
{
    protected static string LogName { get { return "Specific"; } }
}

这是alowed，代码

this is alowed, and the code

SpecificLogger.Log("test");

时，altso alowed，但它不会做什么，你会觉得通过看代码

is altso alowed, but it doesn't do what you would think by looking at the code.

它调用 Logger.Log 与 LOGNAME = NULL 。

那么，为什么这可以吗？

So why is this allowed?

推荐答案

的新关键字不覆盖的方法。它代替创建这是独立于原始的相同名称的新方法。这是不可能覆盖一个静态方法，因为他们不是虚拟的。

The new keyword does not override a method. It instead creates a new method of the same name which is independent of the original. It is not possible to override a static method because they are not virtual
