What are the performance differences between immutable collections in C#?

What are the performance differences between immutable collections in C#?

Immutable collections in C# are designed to be thread-safe and provide better performance in certain scenarios, especially when it comes to concurrent access. However, they can be less efficient in terms of memory usage and performance when frequent modifications are needed.

Can you give examples of when to use immutable collections?

Sure! Use immutable collections when you need to ensure data integrity in multi-threaded applications, or when you want to avoid side effects from modifying shared data.

How do immutable collections compare to mutable ones in terms of speed?

Immutable collections can be slower for operations that require frequent updates, as each modification creates a new instance. Mutable collections are generally faster for these operations.

Are there specific types of immutable collections in C#?

Yes, C# provides several types of immutable collections, such as ImmutableList, ImmutableArray, ImmutableDictionary, and ImmutableHashSet.
