Get actual type of T in a generic List<T>

I m looping through a PropertyInfo-List from a Class. In this class, I m interested in the different Lists - for example List<int>, List<string>, List<Book>, aso.

但我不知道我如何掌握清单目标类型。我只想看到这样的东西。

System.Collections.Generic.List`1[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, 
PublicKeyToken=b77a5c561934e089]].

我可以把这一信息分开,从这种信息中创造出一种类型,但我希望情况更加顺利?

Answer 1

简单:

Type type = list.GetType().GetGenericArguments()[0];
// The first argument will be the `T` inside `List<T>`... so the list type ;)

Answer 2

var  list = GetListFromFoo();
Type listType = list.GetType();
Type theTypeOfT = listType.GetGenericArguments()[0];

或一行:

list.GetType().GetGenericArguments()[0];
