HttpFileCollectionBase Class

Serves as the base class for classes that provide access to files that were uploaded by a client.

Namespace:  System.Web
Assembly:  System.Web (in System.Web.dll)
public abstract class HttpFileCollectionBase : NameObjectCollectionBase, 
	ICollection, IEnumerable

The HttpFileCollectionBase type exposes the following members.

  Name Description
Protected method HttpFileCollectionBase Initializes the class for use by an inherited class instance. This constructor can only be called by an inherited class.

  Name Description
Public property AllKeys When overridden in a derived class, gets an array that contains the keys (names) of all posted file objects in the collection.
Public property Count When overridden in a derived class, gets the number of posted file objects in the collection. (Overrides NameObjectCollectionBase.Count.)
Protected property IsReadOnly Gets or sets a value indicating whether the NameObjectCollectionBase instance is read-only. (Inherited from NameObjectCollectionBase.)
Public property IsSynchronized When overridden in a derived class, gets a value that indicates whether access to the collection is thread-safe.
Public property Item[Int32] When overridden in a derived class, gets the posted file object at the specified index.
Public property Item[String] When overridden in a derived class, gets the posted file object that has the specified name from the collection.
Public property Keys Gets a NameObjectCollectionBase.KeysCollection instance that contains all the keys in the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.)
Public property SyncRoot When overridden in a derived class, gets an object that can be used to synchronize access to the collection.

The HttpFileCollectionBase class is an abstract class that contains the same members as the HttpFileCollection class. The HttpFileCollectionBase class lets you create derived classes that are like the HttpFileCollection class, but that you can customize and that work outside the ASP.NET pipeline. When you perform unit testing, you typically use a derived class to implement members with customized behavior that fulfills the scenario that you are testing.

The HttpFileCollectionWrapper class derives from the HttpFileCollectionBase class. The HttpFileCollectionWrapper class serves as a wrapper for the HttpFileCollection class. At run time, you typically use an instance of the HttpFileCollectionWrapper class to call members of the HttpFileCollection object.
