C#泛型的typedef [英] C# typedef generics
问题描述
我使用一类的简写版,它看起来像这样:
使用NodeSteps =元组LT;节点,INT> ;;
节点是自己定义的类。这工作通常是罚款,但这里的问题是,在该节点是一个通用的,需要一个结构
我的问题如下:
1。
如何这些所谓的typedef在C#中。我知道他们是不完全类型定义,但它是我能想到的最类似的事情。
2。
我怎样才能仿制
使用NodeSteps< T> =元组LT;节点< T> ;, INT取代;
我注意到这是不是这样做的方式。我也想指定T是一个结构。
-
他们被称为别名
-
没有,这是不可能的。 C#语言规范:
使用别名可以命名一个封闭构造类型,但是不能命名。绑定的泛型类型声明没有提供类型参数
块引用>
因此,
用x< T> =列表< T>
或类似的东西是不可能的。
您可以使用一个类(见其他答案(S)),而不是
I am using a shorthand version for a class, which looks like this:
using NodeSteps = Tuple<Node, int>;
Node is a class defined by myself. This works fine usually, but the problem here is, is that Node is a generic requiring a struct.
My questions are as follows:
1. How are these typedefs called in C#. I know they are not exactly typedefs, but it was the most similar thing I could think of.
2. How can I make a generic version?
using NodeSteps<T> = Tuple<Node<T>, int>;
I noticed this is not the way to do it. I also would like to specify T is a struct.
解决方案
They are called aliases.
No, this isn't possible. C# Language spec:
Using aliases can name a closed constructed type, but cannot name an unbound generic type declaration without supplying type arguments.
Therefore,
using x<T> = List<T>
or something similar isn't possible.You may use a class (see the other answers(s)) instead.
