FindIndex(Predicate<T>)

Searches for an element that matches the conditions defined by the specified predicate, and returns the zero-based index of the first occurrence within the entire immutable list.
FindIndex(Int32, Predicate<T>)

Searches for an element that matches the conditions defined by the specified predicate, and returns the zero-based index of the first occurrence within the range of elements in the immutable list that extends from the specified index to the last element.
FindIndex(Int32, Int32, Predicate<T>)

Searches for an element that matches the conditions defined by the specified predicate, and returns the zero-based index of the first occurrence within the range of elements in the immutable list that starts at the specified index and contains the specified number of elements.
