i have interface idomain 1 method gives me element type of domain:

interface idomain {     type elementtype { get; } }

i want create collection of appropriate element type given idomain. how do that?

the following not work:

idomain dom = ... // somewhere type elemtype = dom.elementtype; icollection<elemtype> mycoll = new hashset<elemtype>(); // error: "'elemtype' variable used type"

writing icollection<typeof(elemtype)> not either.

it should noted dom.elementtype can of type a, b or c. know @ point of code, because wrote way.
