I am aware of two methods of casting types to IEnumerable
from an Arraylist
in Linq and wondering in which cases to use them?
e.g
IEnumerable<string> someCollection = arrayList.OfType<string>()
or
IEnumerable<string> someCollection = arrayList.Cast<string>()
What is the difference between these two methods and where should I apply each case?

OfType
- return only the elements that can safely be cast to type x.Cast
- will try to cast all the elements into type x. if some of them are not from this type you will getInvalidCastException
EDIT
for example:
