DelegatingHandler Class

DelegatingHandler Class

.NET Framework 4.6 and 4.5

A type for HTTP handlers that delegate the processing of HTTP response messages to another handler, called the inner handler.

Namespace:  System.Net.Http
Assembly:  System.Net.Http (in System.Net.Http.dll)

public abstract class DelegatingHandler : HttpMessageHandler

The DelegatingHandler type exposes the following members.

Protected methodDelegatingHandler()Creates a new instance of the DelegatingHandler class.
Protected methodDelegatingHandler(HttpMessageHandler)Creates a new instance of the DelegatingHandler class with a specific inner handler.

Public propertyInnerHandlerGets or sets the inner handler which processes the HTTP response messages.

Public methodDispose()Releases the unmanaged resources and disposes of the managed resources used by the HttpMessageHandler. (Inherited from HttpMessageHandler.)
Protected methodDispose(Boolean)Releases the unmanaged resources used by the DelegatingHandler, and optionally disposes of the managed resources. (Overrides HttpMessageHandler.Dispose(Boolean).)
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Protected methodSendAsyncSends an HTTP request to the inner handler to send to the server as an asynchronous operation. (Overrides HttpMessageHandler.SendAsync(HttpRequestMessage, CancellationToken).)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

This application normally instantiate this class and then set the inner handler or provide an inner handler in the constructor.

Note that InnerHandler property may be a delegating handler too. This approach allows the creation of handler stacks to process the HTTP response messages.
