How do I get a Type instance that represents an array of a given Type instance?

Hi,

I have the following scenario. (The example code is C#.)

    Type elementType = (given);
    Type arrayType = (an array of whatever type "elementType" represents);

The question is, how do I get that value that's assigned to arrayType?

The following code works, but it seems kludgy, since it involves a string
parsing and lookup at runtime.

    Type arrayType = Type.GetType(elementType.FullName + "[]");

Does anyone know of a better way?

Thanks,
Jeff Brown

That's the way to do it in v1.x of the framework. Note that you may
have to append the assembly name as well.

In v2.0 there's a new Type.MakeArrayType() method for this.
