How to resolve dependency based on type as string using Autofac

I have a generic interface, say IGeneric which I want to resolve dynamically based on the types that I have as string. To make it clearer, I can resolve the dependency like this:

container.Resolve<IGeneric<AType>>();

But my question is how to resolve it when I have this: 

var type = "AType";

Is there any way apart from (better than) registering every possible class that can be used in place of AType as a named instance?

Use the prototype of Resolve that accepts a Type.

Type type = System.Type.GetType("AType");
var instance = container.Resolve(type);

Or (not sure which one you want) to resolve for IGeneric<Atype> use:

Type genericType = typeof(IGeneric<>);
Type specificType = genericType.MakeGenericType(new [] {Type.GetType("AType")});
var instance = container.Resolve(specificType );
