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,

System_CAPS_protpropertyIsReadOnly

Gets or sets a value indicating whether the NameObjectCollectionBase instance is read-only.(Inherited from NameObjectCollectionBase.)

System_CAPS_pubpropertyIsSynchronized

When overridden in a derived class, gets a value that indicates whether access to the collection is thread-safe.

System_CAPS_pubpropertyItem[Int32]

When overridden in a derived class, gets the posted file object at the specified index.

System_CAPS_pubpropertyItem[String]

When overridden in a derived class, gets the posted file object that has the specified name from the collection.

System_CAPS_pubpropertyKeys

Gets a NameObjectCollectionBase.KeysCollection instance that contains all the keys in the NameObjectCollectionBase instance.(Inherited from NameObjectCollectionBase.)

System_CAPS_pubpropertySyncRoot

When overridden in a derived class, gets an object that can be used to synchronize access to the collection.

NameDescription

Returns an Object array that contains all the values in the NameObjectCollectionBase instance.(Inherited from NameObjectCollectionBase.)

System_CAPS_protmethodBaseGetAllValues(Type)

Returns an array of the specified type that contains all the values in the NameObjectCollectionBase instance.(Inherited from NameObjectCollectionBase.)

System_CAPS_protmethodBaseGetKey(Int32)

Gets the key of the entry at the specified index of the NameObjectCollectionBase instance.(Inherited from NameObjectCollectionBase.)

System_CAPS_protmethodBaseHasKeys()

Gets a value indicating whether the NameObjectCollectionBase instance contains entries whose keys are not null.(Inherited from NameObjectCollectionBase.)

System_CAPS_protmethodBaseRemove(String)

Removes the entries with the specified key from the NameObjectCollectionBase instance.(Inherited from NameObjectCollectionBase.)

System_CAPS_protmethodBaseRemoveAt(Int32)

Removes the entry at the specified index of the NameObjectCollectionBase instance.(Inherited from NameObjectCollectionBase.)

System_CAPS_protmethodBaseSet(Int32, Object)

Sets the value of the entry at the specified index of the NameObjectCollectionBase instance.(Inherited from NameObjectCollectionBase.)

System_CAPS_protmethodBaseSet(String, Object)

Sets the value of the first entry with the specified key in the NameObjectCollectionBase instance, if found; otherwise, adds an entry with the specified key and value into the NameObjectCollectionBase instance.(Inherited from NameObjectCollectionBase.)

System_CAPS_pubmethodCopyTo(Array, Int32)

When overridden in a derived class, copies the elements of the collection to an array, starting at the specified index in the array.

System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGet(Int32)

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.

.NET Framework
Available since 3.5

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