MicroElements source only package: Collection extensions.

Source only package does not forces binary reference on it. Just add package and use as code.



Returns not null (empty) enumeration if input is null.

string? GetFirstName(IEnumerable<string>? names)
    return names


Iterates values and executes action for each value. It's like List.ForEach but works with lazy enumerations and does not forces additional allocations.

// Iterates values and outputs to console.
    .Range(1, 100_000)


Represents ThreadSafe cache that holds only limited number of items. Can be used as drop in replacement for ConcurrentDictionary.

Use it when you need simple cache but with memory limit.


  • Cache organized in two layers: hot and cold.
  • Items first added to cold cache.
  • GetValue first checks hot cache. If value not found in hot cache than cold cache uses for search.
  • If value exists in cold cache than item moves to hot cache.
  • If hot cache exceeds item limit then hot cache became cold cache and new hot cache creates.
