ISequence(T).IndexWhere Method (Func(T, Boolean), Int32)

ISequence T IndexWhere Method (Func T, Boolean , Int32)

A Sandcastle Documented Class Library

Finds the index of the first element satisfying some predicate after or at some start index. If this sequence represents an infinite set or series and no element satisfies the predicate, this will never return!
