c# Creating an unknown generic type at runtime

Question

So I have a class that is a generic and it may need to, inside a method of its own, create an instance of itself with a different kind of generic, whose type is obtained thr

Answer 1

I think you're looking for the MakeGenericType method:

// Assuming that Property.PropertyType is something like List<T>
Type elementType = Property.PropertyType.GetGenericArguments()[0];
Type repositoryType = typeof(GenericRepository<>).MakeGenericType(elementType);
var repository = Activator.CreateInstance(repositoryType);

Answer 2

Activator.CreateInstance(typeof(GenericRepository<>).MakeGenericType(new Type[] { Property.GetTYpe() }))
