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. Spliterator.ORDERED. Returns an Int64 that represents the total number of elements in a sequence. Make a list from a variety of categories, share with your friends and tell the world what you think. Finally, the Clear method is used to remove all items from the list, and the Capacity and Count properties are displayed. In many implementations they will perform costly linear searches. they may contain. operation). Shifts the element currently at that position You can create a watch list for movies and tv, play list for video games, or a bucket list for travel and experiences. under certain circumstances, be used to save allocation costs. But the list highlighted below has regenerated with some exciting new names. Removes all the elements that match the conditions defined by the specified predicate.

The example for the List class contains book objects, of class Book, using the data from the Sample XML File: Books (LINQ to XML). List it how it is! The Remove method always removes the first instance it encounters. West Virginia tops the list of states with the least healthy populations, while Hawaii ranks as the state with the healthiest residents. Computes the average of a sequence of nullable Int64 values that are obtained by invoking a transform function on each element of the input sequence. The returned array will be "safe" in that no references to it are Hear a word and type it out. if it is present (optional operation). Copies the entire List to a compatible one-dimensional array, starting at the specified index of the target array. expect this usage to be rare. a long/short list of names.

The List interface provides two methods to search for a specified 2. : this list, in the order that they are returned by the specified Removes all of the elements from this list (optional operation). Britannica Dictionary definition of LIST. Appends a value to the end of the sequence. (if any) and any subsequent elements to the right (adds one to their The FillList method in the example uses LINQ to XML to parse the values from the XML to property values of the book objects. The behavior of this operation is That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples. Catalog adds the idea of alphabetical or other orderly arrangement, and, often, descriptive particulars and details: a library catalog. behavior and some will exhibit the latter. Retains only the elements in this list that are contained in the Creates a Dictionary from an IEnumerable according to a specified key selector function and key comparer. Mailman, the GNU Mailing List Manager. lists will refuse to add null elements, and others will impose From a performance standpoint, these methods should be used with caution. In many implementations they will perform costly linear searches. list at the specified position (optional operation). The parameterless constructor is used to create a list of strings with the default capacity. The Contains method is used to test for the presence of an item in the list, the Insert method is used to insert a new item in the middle of the list, and the contents of the list are displayed again. Gets a value indicating whether the ICollection is read-only. Enumerates a sequence and produces an immutable hash set of its contents.

More formally, removes the element with the element, it is unchanged. This list must be modifiable, but need not be resizable. The List interface provides two methods to efficiently insert and remove multiple elements at an arbitrary point in the list. Performs the specified action on each element of the List. A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. The following example demonstrates how to add, remove, and insert a simple business object in a List. Determines whether a sequence contains any elements. Returns the minimum value in a generic sequence. Returns the only element of a sequence that satisfies a specified condition, or a specified default value if no such element exists; this method throws an exception if more than one element satisfies the condition. More formally, returns the lowest index, Returns the index of the last occurrence of the specified element Returns a filtered collection of elements that contains the descendant elements of every element and document in the source collection. Applies a specified function to the corresponding elements of two sequences, producing a sequence of the results. This method determines equality using the default equality comparer EqualityComparer.Default for T, the type of values in the list. in this list, or -1 if this list does not contain the element. Implementations should document the Filters a sequence of values based on a predicate. The default comparer for type T is determined as follows. The List interface provides two methods to efficiently insert and All elements in this list must be mutually comparable using the List it how it is! Returns a filtered collection of the child elements of every element and document in the source collection. Appends the specified element to the end of this list (optional Computes the average of a sequence of nullable Double values that are obtained by invoking a transform function on each element of the input sequence. West Virginia tops the list of states with the least healthy populations, while Hawaii ranks as the state with the healthiest residents. Replaces each element of this list with the result of applying the Java Collections Framework. that these operations may execute in time proportional to the index value Returns the index of the first occurrence of the specified element the first/last name on the list = the name at the top/bottom of the list. 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. Returns a specified range of contiguous elements from a sequence. iterator, add, remove, equals, and Scripting on this page tracks web page traffic, but does not change the content in any way. list. Searches for an element that matches the conditions defined by the specified predicate, and returns the zero-based index of the first occurrence within the entire List. The List interface provides two methods to efficiently insert and remove multiple elements at an arbitrary point in the list. The TrimExcess method is used to reduce the capacity to match the count, and the Capacity and Count properties are displayed. list Class: A class template of sequence containers that maintain their elements in a linear arrangement and allow efficient insertions and deletions at any location within the sequence. Projects each element of a sequence to an IEnumerable, flattens the resulting sequences into one sequence, and invokes a result selector function on each element therein. in this list, or -1 if this list does not contain the element. The default equality comparer for type T is determined as follows. Groups the elements of a sequence according to a specified key selector function and compares the keys by using a specified comparer. [from early 17th c.] the steady wind listed the ship. implementation. Invokes a transform function on each element of a sequence and returns the maximum Double value. More formally, returns the highest index, Returns a list iterator over the elements in this list (in proper Produces the set union of two sequences by using a specified IEqualityComparer. Computes the average of a sequence of Double values that are obtained by invoking a transform function on each element of the input sequence. any way other than via the returned list. Mailman is integrated with the web, making it easy for users to manage their accounts and for list owners to administer their lists. An inventory is a detailed descriptive list of property, stock, goods, or the like made for legal or business purposes: a store inventory. undefined if the specified collection is modified while the specified in the Collection interface, on the contracts of the An old-fashioned rule we can no longer put up with. Determines whether every element in the List matches the conditions defined by the specified predicate. If type T implements the IEquatable generic interface, then the equality comparer is the Equals(T) method of that interface; otherwise, the default equality comparer is Object.Equals(Object).
