C5 is a generic collection library for C# and other .NET/CLI languages, providing a wide range of classic data structures such as lists, sets, bags, dictionaries, priority queues, and updatable views. It emphasizes rich functionality, orthogonal interfaces, documented asymptotic performance, and a thoroughly tested implementation.
Use cases
- need advanced data structures like priority queues or tree dictionaries in C#
- want richer collection functionality than System.Collections.Generic
- require updatable views or snapshots of collections
- need guaranteed asymptotic time complexity for collection operations
- looking for a well-tested alternative collection library for .NET
- want a common interface across list-like collection implementations
When to choose
- you need data structures or advanced features (views, snapshots, priority queue handles) missing from the standard .NET collections
- you care about documented performance guarantees and orthogonality of collection interfaces
- you work in C#, F#, or VB.NET on modern .NET runtimes
When to avoid
- your needs are fully covered by System.Collections.Generic
- you want a library with frequent updates and a large active community
- you target platforms without generics-enabled .NET runtime support
