Indexerable

Issues Stars NuGet

Indexerable provides LINQ-style operations for IReadOnlyList<T>. Its list-oriented operators let you compose queries while retaining indexed access, without first materializing each intermediate result.

Support Platform

  • .NET Framework 4.5
  • .NET Framework 4.7
  • .NET Framework 4.7.1
  • .NET Standard 1.0
  • .NET Standard 1.2
  • .NET Standard 2.0
  • .NET Standard 2.1
  • .NET Core 5.0
  • .NET Core App 2.0
  • .NET Core App 2.1
  • .NET Core App 3.0
  • .NET 6.0
  • .NET 7.0
  • .NET 8.0
  • .NET 9.0

Install

dotnet add package Indexerable

Then import the extension-method namespace:

using System;
using System.Collections.Generic;
using Indexer.Linq;

Quick start

using Indexer.Linq;

IReadOnlyList<int> values = Indexerable.Range(1, 5);
IReadOnlyList<int> result = values
    .Select((value, index) => value * (index + 1))
    .Skip(1)
    .Take(3);

Console.WriteLine(result.Count);                // 3
Console.WriteLine(result[1]);                   // 9
Console.WriteLine(string.Join(", ", result));   // 4, 9, 16

Available operations

All extension methods operate on IReadOnlyList<T> unless noted.

Category Methods
Create sequences Range, Repeat, Empty, InfiniteSequence
Adapt lists AsReadOnlyList, ToReadOnlyList, Cast
Transform and combine Select, Append, Prepend, Concat, Zip, Reverse, Index
Select a portion Skip, SkipLast, Take, TakeLast
Search IndexOf(value), IndexOf(predicate)
Copy elements CopyTo

ToReadOnlyList also has an overload for string, which exposes its characters as a read-only list. InfiniteSequence<T> is available on .NET 7 and later targets.

How queries behave

  • Sequence-producing operations return IReadOnlyList<T>, with Count, indexed access, and foreach. Search operations such as IndexOf return an index, while CopyTo copies elements into an array.
  • Most operators return lightweight list views. Elements are generally computed when accessed or enumerated rather than materialized into a new collection. For example, Select invokes its selector each time an item is accessed; projected values are not cached.
  • Views over an existing list retain that source rather than taking a snapshot, so changes to a mutable source may be visible through the view.
  • Most operators require an IReadOnlyList<T>. Convert an IList<T> with ToReadOnlyList when needed; it wraps the source rather than copying it.
  • InfiniteSequence is unbounded. Apply Take before enumerating it fully.
