Remarks
NoteNote

To view the .NET Framework source code for this type, see the Reference Source. You can browse through the source code online, download the reference for offline viewing, and step through the sources (including patches and updates) during debugging; see instructions.

The ListT class is the generic equivalent of the ArrayList class. It implements the IListT generic interface by using an array whose size is dynamically increased as required.

You can add items to a ListT by using the Add or AddRange methods.

The ListT class uses both an equality comparer and an ordering comparer.

  • Methods such as Contains, IndexOf, LastIndexOf, and Remove use an equality comparer for the list elements. The default equality comparer for type T is determined as follows. If type T implements the IEquatableT generic interface, then the equality comparer is the Equals(T) method of that interface; otherwise, the default equality comparer is ObjectEquals(Object).

  • Methods such as BinarySearch and Sort use an ordering comparer for the list elements. The default comparer for type T is determined as follows. If type T implements the IComparableT 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. If type T implements neither interface, then there is no default comparer, and a comparer or comparison delegate must be provided explicitly.

The ListT is not guaranteed to be sorted. You must sort the ListT before performing operations (such as BinarySearch) that require the ListT to be sorted.

Elements in this collection can be accessed using an integer index. Indexes in this collection are zero-based.

For very large ListT objects, you can increase the maximum capacity to 2 billion elements on a 64-bit system by setting the enabled attribute of the gcAllowVeryLargeObjects configuration element to true in the run-time environment.

ListT accepts as a valid value for reference types and allows duplicate elements.

For an immutable version of the ListT class, see ImmutableList.

Performance Considerations

In deciding whether to use the ListT or ArrayList class, both of which have similar functionality, remember that the ListT class performs better in most cases and is type safe. If a reference type is used for type T of the ListT class, the behavior of the two classes is identical. However, if a value type is used for type T, you need to consider implementation and boxing issues.

If a value type is used for type T, the compiler generates an implementation of the ListT class specifically for that value type. That means a list element of a ListT object does not have to be boxed before the element can be used, and after about 500 list elements are created the memory saved not boxing list elements is greater than the memory used to generate the class implementation.

Make certain the value type used for type T implements the IEquatableT generic interface. If not, methods such as Contains must call the ObjectEquals(Object) method, which boxes the affected list element. If the value type implements the IComparable interface and you own the source code, also implement the IComparableT generic interface to prevent the BinarySearch and Sort methods from boxing list elements. If you do not own the source code, pass an IComparerT object to the BinarySearch and Sort methods

It is to your advantage to use the type-specific implementation of the ListT class instead of using the ArrayList class or writing a strongly typed wrapper collection yourself. The reason is 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.

F# Considerations

The List<T> class is used infrequently in F# code. Instead, Lists (F#), which are immutable, singly-linked lists, are typically preferred. An F# List provides an ordered, immutable series of values, and is supported by the List Module for use in functional-style development. When used from F#, the List<T> class is typically referred to by the ResizeArray<’T> type abbreviation to avoid naming conflicts with F# Lists

The following example demonstrates several properties and methods of the ListT generic class of type string. (For an example of a ListT of complex types, see the Contains method.)

The default constructor is used to create a list of strings with the default capacity. The Capacity property is displayed and then the Add method is used to add several items. The items are listed, and the Capacity property is displayed again, along with the Count property, to show that the capacity has been increased as needed.

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.

The default Item property (the indexer in C#) is used to retrieve an item, the Remove method is used to remove the first instance of the duplicate item added earlier, and the contents are displayed again. The Remove method always removes the first instance it encounters.

The TrimExcess method is used to reduce the capacity to match the count, and the Capacity and Count properties are displayed. If the unused capacity had been less than 10 percent of total capacity, the list would not have been resized.

Finally, the Clear method is used to remove all items from the list, and the Capacity and Count properties are displayed.

Thread Safety

Public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

It is safe to perform multiple read operations on a ListT, but issues can occur if the collection is modified while it’s being read. To ensure thread safety, lock the collection during a read or write operation. To enable a collection to be accessed by multiple threads for reading and writing, you must implement your own synchronization. For collections with built-in synchronization, see the classes in the System.Collections.Concurrent namespace. For an inherently thread–safe alternative, see the ImmutableList class.
