fill an object instance via AutoFixture, but not by a generic but by type

Question

Is it possible to either create an object by type, for example:

Type typeToCreate = typeof(TestModel);
Fixture fixture = new Fixture();
var item = fixture.Create(typeToCreate)

Or something where I can pass an already created object and it is filled, for example:

fixture.Fill(myAlreadyCreatedObject);

I could only manage to create items by generics, like fixture.Create<MyType>(). This works fine, but generics sometimes limit you if the type is determined at runtime.

Yes, that's possible. You may want to look at this [answer](http://stackoverflow.com/a/18954051/467754). — Nikos Baxevanis, Oct 22 '14 at 08:54
Thanks for pointing that out, works perfect! If you post it as answer I can accept it, as it is the answer. — Karl Cassar, Oct 23 '14 at 10:15
@NikosBaxevanis If you add the answer it'd be nice, because it means that the question would no longer look unanswered in list views. — Mark Seemann, Nov 29 '15 at 19:34
What about filling an existing object without creating a new one? — joe, May 18 '21 at 02:51

Yes, that's possible with AutoFixture.

You may want to look at this answer which shows an example of it.
