what C# collections

Question

explain C# collections

Answer 1

Collections types (the ones found in the "System.Collections.Generic" namespace) are classes that can hold a number of elements. Where a variable might hold one element (int a = 1), Collections can hold as many as you want (var list = new List<int> { 1, 2, 3 }). Collections such as List and Dictionary are used in virtually every program for every kind of situation you could think of, such as holding a bunch of classes that represent customers.

Answer 2

I think you need to supply more contextual information, before you can get a definition.  Most likely this term occurs in the field that you are studying, so the best place to look would be in the textbook or manual.
