IList Interface
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Represents a non-generic collection of objects that can be individually accessed by index.
Assembly: mscorlib (in mscorlib.dll)
The IList type exposes the following members.
| Name | Description | |
|---|---|---|
 | Count | Gets the number of elements contained in the ICollection. (Inherited from ICollection.) |
| IsFixedSize | Gets a value indicating whether the IList has a fixed size. |
| IsReadOnly | Gets a value indicating whether the IList is read-only. |
| IsSynchronized | Gets a value indicating whether access to the ICollection is synchronized (thread safe). (Inherited from ICollection.) |
| Item | Gets or sets the element at the specified index. |
| SyncRoot | Gets an object that can be used to synchronize access to the ICollection. (Inherited from ICollection.) |
| Name | Description | |
|---|---|---|
 | Add | Adds an item to the IList. |
| Clear | Removes all items from the IList. |
| Contains | Determines whether the IList contains a specific value. |
| CopyTo | Copies the elements of the ICollection to an Array, starting at a particular Array index. (Inherited from ICollection.) |
| GetEnumerator | Returns an enumerator that iterates through a collection. (Inherited from IEnumerable.) |
| IndexOf | Determines the index of a specific item in the IList. |
| Insert | Inserts an item to the IList at the specified index. |
| Remove | Removes the first occurrence of a specific object from the IList. |
| RemoveAt | Removes the IList item at the specified index. |
| Name | Description | |
|---|---|---|
 | AsQueryable | Converts an IEnumerable to an IQueryable. (Defined by Queryable.) |
| Cast<TResult> | Converts the elements of an IEnumerable to the specified type. (Defined by Enumerable.) |
| OfType<TResult> | Filters the elements of an IEnumerable based on a specified type. (Defined by Enumerable.) |
IList is a descendant of the ICollection interface and is the base interface of all non-generic lists. IList implementations fall into three categories: read-only, fixed-size, and variable-size. A read-only IList cannot be modified. A fixed-size IList does not allow the addition or removal of elements, but it allows the modification of existing elements. A variable-size IList allows the addition, removal, and modification of elements.
For the generic version of this interface, see System.Collections.Generic::IList<T>.
The following example demonstrates the implementation of the IList interface to create a simple list, fixed-size list.
