When to use Cast() and OfType() in Linq
.net, c#, linq
Solution
`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 get `InvalidCastException`
EDIT for example:
object[] objs = new object[] { "12345", 12 };
objs.Cast<string>().ToArray(); //throws InvalidCastException
objs.OfType<string>().ToArray(); //return { "12345" }
Problem
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?
