Definition

Overloads

LastIndexOf<T>(IImmutableList<T>, T)

Searches for the specified object and returns the zero-based index of the last occurrence within the entire immutable list.

LastIndexOf<T>(IImmutableList<T>, T, IEqualityComparer<T>)

Searches for the specified object and returns the zero-based index of the last occurrence within the entire immutable list.

LastIndexOf<T>(IImmutableList<T>, T, Int32)

Searches for the specified object and returns the zero-based index of the last occurrence within the range of elements in the immutable list that extends from the first element to the specified index.

LastIndexOf<T>(IImmutableList<T>, T, Int32, Int32)

Searches for the specified object and returns the zero-based index of the last occurrence within the range of elements in the immutable list that extends from the first element to the specified index.
