What are some common performance issues with collections in C#?

Some common performance issues include excessive memory usage, inefficient searching, and poor iteration performance.

Can you explain why excessive memory usage happens?

Excessive memory usage can occur when collections grow dynamically, leading to frequent reallocations and memory fragmentation.

What about searching inefficiencies?

Inefficient searching often happens with collections like lists, where linear search is used instead of more efficient structures like hash sets.

How can I improve iteration performance?

To improve iteration performance, consider using arrays or lists instead of linked lists, as they provide better cache locality.
