c# - Can ViewModel have property of type IEnumerable<> instead of Array -

i construct viewmodel this:

myviewmodel {   (...)   ienumerable<myclass> items {get; set;} } 

should ever care (be afraid) not passing evaluated values in code below?

myviewmodel {   myclass[] items {get; set;} } 

sometimes lazy evaluation causes problems.

just make sure new concrete instance of ienumerable in view model constructor, , shouldn't have problems. list empty.
