[from early 17th c.] the steady wind listed the ship. List (abstract data type) In computer science, a list or sequence is an abstract data type that represents a finite number of ordered values, where the same value may occur more than once. The behavior of this Each element's index is used in the logic of the predicate function. In deciding whether to use the List or ArrayList class, both of which have similar functionality, remember that the List class performs better in most cases and is type safe. specified collection (optional operation). You must sort the List before performing operations (such as BinarySearch) that require the List to be sorted. Finally, the Clear method is used to remove all items from the list, and the Capacity and Count properties are displayed. Returns a number that represents how many elements in the specified sequence satisfy a condition. Invokes a transform function on each element of a sequence and returns the minimum nullable Double value. If type T implements the IComparable generic interface, then the default comparer is the CompareTo(T) method of that interface; otherwise, if type T implements the nongeneric IComparable interface, then the default comparer is the CompareTo(Object) method of that interface. list at the specified position (optional operation). An F# List provides an ordered, immutable series of values, and is supported for use in functional-style development. Ensures that the capacity of this list is at least the specified capacity. The index of each source element is used in the projected form of that element. It implements the IList generic interface by using an array whose size is dynamically increased as required.

The List interface provides a special iterator, called a a record of short pieces of information, such as people's names, usually written or printed with a single thing on each line and often ordered in a way that makes How to use a word that (literally) drives some pe Editor Emily Brewster clarifies the difference. That means a list element of a List object does not have to be boxed before the element can be used, and after about 500 list elements are created, the memory saved by not boxing list elements is greater than the memory used to generate the class implementation.

An element of the original list is set to "Coelophysis" using the Item[] property (the indexer in C#), and the contents of the read-only list are displayed again to demonstrate that it is just a wrapper for the original list.
