HttpApplicationStateBase Class

Definition

Serves as the base class for classes that enable information to be shared across multiple sessions and requests within an ASP.NET application.

public ref class HttpApplicationStateBase abstract : System::Collections::Specialized::NameObjectCollectionBase, System::Collections::ICollection
public abstract class HttpApplicationStateBase : System.Collections.Specialized.NameObjectCollectionBase, System.Collections.ICollection
type HttpApplicationStateBase = class
    inherit NameObjectCollectionBase
    interface ICollection
    interface IEnumerable

Remarks

The HttpApplicationStateBase class is an abstract class that contains the same members as the HttpApplicationState class. The HttpApplicationStateBase class lets you create derived classes that are like the HttpApplicationState 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 you are testing.

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

Constructors

HttpApplicationStateBase()

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 the access keys for the objects in the collection.

Contents

When overridden in a derived class, gets a reference to the HttpApplicationStateBase object.

Count

When overridden in a derived class, gets the number of 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 a state object by index.

Item[String]

When overridden in a derived class, gets a state object by name.

Keys

Gets a NameObjectCollectionBase.KeysCollection instance that contains all the keys in the NameObjectCollectionBase instance.

(Inherited from NameObjectCollectionBase)
StaticObjects

When overridden in a derived class, gets all objects that are declared by an object element where the scope is set to "Application" in the ASP.NET application.

SyncRoot

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

Methods

Add(String, Object)

When overridden in a derived class, adds a new object to the collection.

BaseAdd(String, Object)

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)

(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)
Clear()

When overridden in a derived class, removes all objects from the collection.

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, gets a state object by index.

Get(String)

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, gets the name of a state object by index.

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)
Lock()

When overridden in a derived class, locks access to objects in the collection in order to enable synchronized access.

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)
Remove(String)

When overridden in a derived class, removes the named object from the collection.

RemoveAll()

When overridden in a derived class, removes all objects from the collection.

RemoveAt(Int32)

Set(String, Object)

When overridden in a derived class, updates the value of an object in the collection.

ToString()

Returns a string that represents the current object.

(Inherited from Object)
UnLock()

When overridden in a derived class, unlocks access to objects in the collection to enable synchronized access.

Explicit Interface Implementations
