ListIndexOf

List writer that searches index of element implements IWriterToRef<(List, Element), Long>.

IWriterToRef<(List<int>, int), long> listIndexOf;

Creating a writer

ListIndexOf<List, Element> is the default implementation IList<T>.

IWriterToRef<(List<int>, int), long> listIndexOf = new ListIndexOf<List<int>, int>();

ListIndexOf.Create(listType, elementType) also creates the writer.

IWriterToRef<(List<int>, int), long> listIndexOf =
    (IWriterToRef<(List<int>, int), long>)
    ListIndexOf.Create(typeof(List<int>), typeof(int));

List index of be adapted from delegate.

IWriterToRef<(List<int>, int), long> listIndexOf =
    DelegateWriter.Reader<(List<int>, int), long>(
        ((List<int> list, int element) args) => args.list.IndexOf(args.element)
    );

ListIndexOfRequest(Type) is a request to build a list indexof writer.

ListIndexOfRequest listRequest = new ListIndexOfRequest(typeof(List<int>));
IWriterToRef<(List<int>, int), long> listIndexOf =
    AccessorServices.Instance
    .GetRequired<ListIndexOfRequest, IWriterToRef<(List<int>, int), long>>(listRequest);

Usage

Writer finds index of an element.

List<int> list = new List<int> { 1, 2, 3 };
long index = listIndexOf.Read((list, 2));
