First and Last throw an exception if no result was found. FirstOrDefault and LastOrDefault return the result variable type's default value in that case.

FirstOrDefault and LastOrDefault would not throw an exception if there are no search item in sequence, they will return null.

3Not exactly. They only return null if null is the return type's default value. In case of an integer, they return 0, etc. – Patrick Sep 22 '16 at 07:43

1Ah, if you u wont. They return **variable type`s default value**. – Dmitriy Kovalenko Sep 22 '16 at 07:49
