Question

Assume I have an generic type of an runtime object and a raw generic type of the same class, e.g.

var type = (new List<Int32>()).GetType();
var genericListType = typeof(List<>);

I need kind of GetRawGenericType method, so the expression

GetRawGenericType(type) == genericListType

returns true. Is there a way to implement this ?

Remarks:

I do not know the type of the of the object it may be any generic type.
In the code I’m writing I have to know the exact generic type as it will be used as a key in a Dictionary, for example :

private readonly Dictionary<Type, TValue> Mapping = 
    new Dictionary<Type, TValue> { 
            {typeof(IEnumerable<>), *SomeValue*},
            ...
        }

Thanks in advance for you time spend.

Type.GetGenericTypeDefinition is what you looking for.
