Possible Duplicate:
Generic type from string value

Given a scenario,
Class Car: Transport,
Class Bus: Transport,
Interface Transport,
Get(): Generics Method

Is it possible to do something like this?

Transport t= Get<"Car">(string color);

public T Get<T>(string color)
{
  return new T(color);
}

P/S: There’s a reason to assign it as string, dynamically, regardless of return type.

Answer 1

If you want having Get works with a string you have two options:
Add a non generic Get taking a Type as a paremter, something like:

public object Get(Type t);

so you can pass a type created form a string.
A second option could be reflection:

MethodInfo method = typeof(YourType).GetMethod("Get");
MethodInfo generic = method.MakeGenericMethod(myType);

then you can invoke generic as if it was closed on to the type myType.

If I can suggest which one to use, and if you can refactor the Get method, I would suggest adding a non generic version of that method. The reflection version works if you really can’t modify the library code. The drawback in using reflection is performance as you probably guess: you can decide if you can stay with it or not.

EDIT

Of course, my discussion does not apply if your method is really just creating the final object:

In this case activator works as a charm by passing the complete type name:

Activator.CreateInstance(Type.GetType("yourtypename"));

You generally can create the type based on just the simple name ( Car,Bus, etc ) because you need to fully qualify with a namespace and an assebly if the type is not the ExecutingAssembly. In this case you have to use some convention/configuration to simplify the code readability.

ADDITION

If you need to pass parameters too, I think you can try to start using a simple IoC ( I would not recomend one in particular, choose one widely used you like ) that can solve all these issues for you.
