List is a .net collection that can have a collection of any built-in data type (such as string, int, double etc.) or User defined data types (classes, struct) For example: you could create a List of String in following way: List list = new List (); After that, you need to add elements into that list and then you could perform various operation on that such as: finding element, get first element, get index position of any elemnt etc. Here is the link that also explains varios types of operation of a list of user defined "Person" class: http://www.c-sharpcorner.com/UploadFile/0f68f2/using-lambda-expression-over-a-list-in-C-Sharp/
