C#中的通用约束,T是相同的TSomethingElse,对吧?(Generic constraints in C#, T is the same TSomethingElse, right?)

我经常看到:

public interface IFoo<TWidget> where TWidget : ISomethingElse { }

在这种情况下,TWidget与使用泛型T相同,是否正确? 我发现这个令人惊讶的难以谷歌或在规格中找到。 我99%肯定T +的其他角色与T说的相同,但是想绝对确定。


I often see:

public interface IFoo<TWidget> where TWidget : ISomethingElse { }

In this case, TWidget is the same as using the generic T, correct? I'm finding this surprisingly hard to google or find in the specs. I'm 99% sure that T + any other characters is the same as saying just T, but wanted to be absolutely sure.

最满意答案

泛型类型参数的名称可以通过任何有效的标识符名称。

在大多数文档中,您确实可以在TWidget找到T

来自MSDN:

使用描述性名称命名泛型类型参数,除非单个字母名称完全是自解释的,并且描述性名称不会添加值。


The name of the generic type parameter can by any valid identifier name.

In most documentation you would indeed find T where you put TWidget.

From MSDN:

Do name generic type parameters with descriptive names, unless a single letter name is completely self explanatory and a descriptive name would not add value.
