Remarks

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.

Constructors

HttpFileCollectionBase()

Initializes the class for use by an inherited class instance. This constructor can only be called by an inherited class.

Properties

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

Methods

BaseAdd(String, Object)	Adds an entry with the specified key and value into the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase)
BaseClear()	Removes all entries from the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase)
BaseGet(Int32)	Gets the value of the entry at the specified index of the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase)
BaseGet(String)	Gets the value of the first entry with the specified key from the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase)
BaseGetAllKeys()	Returns a String array that contains all the keys in the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase)
BaseGetAllValues()	Returns an Object array that contains all the values in the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase)
BaseGetAllValues(Type)	Returns an array of the specified type that contains all the values in the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase)
BaseGetKey(Int32)	Gets the key of the entry at the specified index of the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase)
BaseHasKeys()	Gets a value indicating whether the NameObjectCollectionBase instance contains entries whose keys are not `null`. (Inherited from NameObjectCollectionBase)
BaseRemove(String)	Removes the entries with the specified key from the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase)
BaseRemoveAt(Int32)	Removes the entry at the specified index of the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase)
BaseSet(Int32, Object)	Sets the value of the entry at the specified index of the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase)
BaseSet(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)
CopyTo(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.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
Get(Int32)	When overridden in a derived class, returns the posted file object at the specified index.
Get(String)	When overridden in a derived class, returns the posted file object that has the specified name from the collection.
GetEnumerator()	When overridden in a derived class, returns an enumerator that can be used to iterate through the collection.
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetKey(Int32)	When overridden in a derived class, returns the name of the posted file object at the specified index.
GetMultiple(String)	When implemented in a derived class, returns all files that match the specified name.
GetObjectData(SerializationInfo, StreamingContext)	Obsolete. Implements the ISerializable interface and returns the data needed to serialize the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
OnDeserialization(Object)	Implements the ISerializable interface and raises the deserialization event when the deserialization is complete. (Inherited from NameObjectCollectionBase)
ToString()	Returns a string that represents the current object. (Inherited from Object)

Explicit Interface Implementations

ICollection.CopyTo(Array, Int32)	Copies the entire NameObjectCollectionBase to a compatible one-dimensional Array, starting at the specified index of the target array. (Inherited from NameObjectCollectionBase)
ICollection.IsSynchronized	Gets a value indicating whether access to the NameObjectCollectionBase object is synchronized (thread safe). (Inherited from NameObjectCollectionBase)
ICollection.SyncRoot	Gets an object that can be used to synchronize access to the NameObjectCollectionBase object. (Inherited from NameObjectCollectionBase)

Extension Methods

Cast<TResult>(IEnumerable)	Casts the elements of an IEnumerable to the specified type.
OfType<TResult>(IEnumerable)	Filters the elements of an IEnumerable based on a specified type.
AsParallel(IEnumerable)	Enables parallelization of a query.
AsQueryable(IEnumerable)	Converts an IEnumerable to an IQueryable.
