Cast to dynamic list with reflection c#

Question

How to cast a List of X object, based on the name in string?

I have this case:

public void AssignValue(string className, Dataset.Table table){
    Type currentType = Type.GetType("Namespace." + className);
    var objectCasted = (List<currentType.GetType()>)result;
}

Then, I'm trying to cast a List of a dynamic object, how I can do it using reflection?

Do you mean `dynamic` as in the type, or "dynamic" in the sense of "determined at runtime"? What have you tried? — CodeCaster, Mar 16 '18 at 14:06
@ Sebastian I read it, but how to use with a list, is not specified — Benjamin RD, Mar 16 '18 at 14:07
Yeah so see duplicates. Please read [ask] and try searching before asking a new question, then if you do ask one, show what you have tried. — CodeCaster, Mar 16 '18 at 14:08
You can´t do this. Casting is a compile-time-_opertation and requires the type being know at compile-time. Maybe you want to *convert* the items in the list. Have you seen this topic: https://stackoverflow.com/questions/4925718/c-dynamic-runtime-cast? — MakePeaceGreatAgain, Mar 16 '18 at 14:08
If you want to get the list type: `typeof(List<>).MakeGenericType(currentType)`, but what do you want to do with it? — vc 74, Mar 16 '18 at 14:13

You can't cast to a type that is not known at compile time. Since your object is a List, it implements IList which might be good enough to allow you to access to the methods and properties you need:
