How do you remove elements from a List<T> in C#?

Short answer: Use methods like: Remove(item) – removes first occurrence RemoveAt(index) – removes by index RemoveAll(predicate) – removes all matching a condition Clear() – removes all items

Example code

numbers.Remove(10); numbers.RemoveAt(0); numbers.RemoveAll(x => x > 100); numbers.Clear();

Real-world example (ShopNest)

In ShopNest, an order page loads products with List<Product> so you can Add items to the cart and access them by index. Use IEnumerable<T> when you only need to loop (for example, printing invoice lines).

Say this in the interview

  1. Define — one clear sentence (the short answer above).
  2. Example — relate it to a project like ShopNest or your real work.
  3. Trade-off — when you would not use it.
