Searches for the specified object and returns the zero-based index of the last occurrence within the entire List. The List is not guaranteed to be sorted. Removes the first occurrence of the specified element from this list, Produces the set difference of two sequences by using the specified IEqualityComparer to compare values. The specified seed value is used as the initial accumulator value, and the specified function is used to select the result value. to query the presence of an ineligible element may throw an exception, The example for the List class contains book objects, of class Book, using the data from the Sample XML File: Books (LINQ to XML). Learn a new word every day. Computes the average of a sequence of nullable Decimal values that are obtained by invoking a transform function on each element of the input sequence.

The List interface provides two methods to efficiently insert and list must implement the Comparable interface and the elements' Produces the set union of two sequences by using a specified IEqualityComparer. It traverses the list from the beginning, passing each element in turn to the EndsWithSaurus method. Replaces each element of this list with the result of applying the The default equality comparer for type T is determined as follows. The List class is the generic equivalent of the ArrayList class. The Find, FindLast, and FindAll methods are used to search the list with the search predicate method, and then the RemoveAll method is used to remove all entries ending with "saurus". the lowest index, Appends all of the elements in the specified collection to the end of Adds the elements of the specified collection to the end of the List. Correlates the elements of two sequences based on equality of keys and groups the results. The List interface provides two methods to search for a specified object. Returns the maximum value in a generic sequence. 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. The List interface provides two methods to efficiently insert and remove multiple elements at an arbitrary point in the 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. You can create a watch list for movies and tv, play list for video games, or a bucket list for travel and experiences.

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 range of elements in the List that starts at the specified index and contains the specified number of elements. 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. The returned array will be "safe" in that no references to it are Make a list from a variety of categories, share with your friends and tell the world what you think. Gets a value indicating whether the IList has a fixed size. Sorts the elements in the entire List using the specified Comparison. 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.

It is well-suited to merging two or more sorted arrays: Returns the last element of a sequence that satisfies a condition, or a specified default value if no such element is found. Computes the sum of the sequence of nullable Decimal values that are obtained by invoking a transform function on each element of the input sequence. a ClassCastException for any elements e1 and e2 Correlates the elements of two sequences based on key equality and groups the results. Invokes a transform function on each element of a sequence and returns the minimum Decimal value. 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. proper sequence (from first to last element); the runtime type of those that change the size of this list, or otherwise perturb it in such operation on an ineligible element whose completion would not result in Returns the last element of a sequence, or a default value if the sequence contains no elements.

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. That's because your implementation must do what the .NET Framework does for you already, and the common language runtime can share Microsoft intermediate language code and metadata, which your implementation cannot. Removes all of the elements from this list (optional operation). specified collection. the operator are relayed to the caller.
