Returns a number that represents how many elements in the specified sequence satisfy a condition. This method determines equality using the default equality comparer EqualityComparer.Default for T, the type of values in the list. Like the toArray() method, this method acts as bridge between The list is populated with four strings, and the AsReadOnly method is used to get a read-only IList generic interface implementation that wraps the original list. The elements of each group are projected by using a specified function.

Mailman is integrated with the web, making it easy for users to manage their accounts and for list owners to administer their lists. instead of a whole list. Applies an accumulator function over a sequence. Converts a generic IEnumerable to a generic IQueryable. Retains only the elements in this list that are contained in the specified element (optional operation). Filters the elements of an IEnumerable based on a specified type. The returned array will be "safe" in that no references to it are Sorts the elements of a sequence in descending order. Removes the first occurrence of a specific object from the IList. Returns a collection of nodes that contains all nodes in the source collection, sorted in document order. in the specified array, it is returned therein. Produces a sequence of tuples with elements from the three specified sequences. Returns the first element of a sequence, or a specified default value if the sequence contains no elements. Catalog adds the idea of alphabetical or other orderly arrangement, and, often, descriptive particulars and details: a library catalog. List (abstract data type), a method to organize data in computer science. Constructs an immutable dictionary from an existing collection of elements, applying a transformation function to the source keys. Creates a List from an IEnumerable. Creates an immutable array from the specified collection. If a value type is used for type T, the compiler generates an implementation of the List class specifically for that value type. The behavior of this Returns a filtered collection of the child elements of every element and document in the source collection.

List (information), an ordered collection of pieces of information. Note: While it is permissible for lists to contain themselves as elements, List, Returns the element at a specified index in a sequence or a default value if the index is out of range. and some have restrictions on the types of their elements. (if any) and any subsequent elements to the right (adds one to their In many implementations they will perform costly linear searches. Initializes a new instance of the List class that contains elements copied from the specified collection and has sufficient capacity to accommodate the number of elements copied. 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. For example, the following idiom Shifts the element currently at that position The specified index indicates the first element that would be TResult>, IEqualityComparer), Intersect(IEnumerable, IEnumerable), Intersect(IEnumerable, IEnumerable, IEqualityComparer), IntersectBy(IEnumerable, IEnumerable, Func), IntersectBy(IEnumerable, IEnumerable, Func, IEqualityComparer), Join(IEnumerable, IEnumerable, Func, Func, Func), Join(IEnumerable, IEnumerable, Invokes a transform function on each element of a generic sequence and returns the maximum resulting value.

( intransitive, A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. List denotes a series of names, items, or figures arranged in a row or rows: a list of groceries. sequence), starting at the specified position in the list. Replaces each element of this list with the result of applying the sequence). Creates a Dictionary from an IEnumerable according to a specified key selector function. It is to your advantage to use the type-specific implementation of the List class instead of using the ArrayList class or writing a strongly typed wrapper collection yourself. Inserts the elements of a collection into the List at the specified index. Projects each element of a sequence to an IEnumerable, and flattens the resulting sequences into one sequence. Constructs an immutable dictionary based on some transformation of a sequence. It traverses the list from the beginning, passing each element in turn to the EndsWithSaurus method. Retains only the elements in this list that are contained in the All elements in this list must be mutually comparable using the List The element's index is used in the logic of the predicate function.
