TypeScript静态类 [英] TypeScript static classes

问题描述

我想从传统的JS移动到TypeScript，因为我喜欢C＃类似的语法。
我的问题是，我找不到如何在TypeScript中声明静态类。

I wanted to move to TypeScript from traditional JS because I like the C#-like syntax. My problem is that I can't find out how to declare static classes in TypeScript.

在C＃中，我经常使用静态类来组织变量和方法，将它们放在一个命名的类中，而不需要安装对象。
在vanilla JS中，我曾经使用一个简单的JS对象：

In C#, I often use static classes to organize variables and methods, putting them together in a named class, without needing to instatiate an object. In vanilla JS, I used to do this with a simple JS object:

var myStaticClass = {
    property: 10,
    method: function(){}
}

在TypeScript，我宁愿去我的C锐利的方法，但似乎静态类不存在于C＃。
这个问题的适当解决方案是什么？

In TypeScript, I would rather go for my C-sharpy approach, but it seems that static classes don't exist in C#. What is the appropriate solution for this problem ?

推荐答案

TypeScript不是C＃，所以你不应该期望在TypeScript中的C＃的相同概念必然。问题是你为什么想要静态类？

TypeScript is not C#, so you shouldn't expect the same concepts of C# in TypeScript necessarily. The question is why do you want static classes?

在C＃中，静态类是一个不能被子类化的类，只能包含静态方法。 C＃不允许定义类外的函数。但是，在TypeScript中，这是可能的。

In C# a static class is simply a class that cannot be subclassed and must contain only static methods. C# does not allow one to define functions outside of classes. In TypeScript this is possible, however.

如果你正在寻找一种方法将你的函数/方法放在命名空间TypeScript的模块，例如

If you're looking for a way to put your functions/methods in a namespace (i.e. not global), you could consider using TypeScript's modules, e.g.

module M {
    var s = "hello";
    export function f() {
        return s;
    }
}

这样你可以从外部访问Mf

So that you can access M.f() externally, but not s, and you cannot extend the module.
