MessageProcessingHandler Class

.NET Framework 4.5

A base type for handlers which only do some small processing of request and/or response messages.

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

public abstract class MessageProcessingHandler : DelegatingHandler

The MessageProcessingHandler type exposes the following members.

  NameDescription
Public methodSupported in .NET for Windows Store appsDispose()Releases the unmanaged resources and disposes of the managed resources used by the HttpMessageHandler. (Inherited from HttpMessageHandler.)
Protected methodSupported in .NET for Windows Store appsDispose(Boolean)Releases the unmanaged resources used by the DelegatingHandler, and optionally disposes of the managed resources. (Inherited from DelegatingHandler.)
Public methodSupported in .NET for Windows Store appsEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodSupported in .NET for Windows Store appsFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodSupported in .NET for Windows Store appsGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodSupported in .NET for Windows Store appsGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodSupported in .NET for Windows Store appsMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Protected methodSupported in .NET for Windows Store appsProcessRequestPerforms processing on each request sent to the server.
Protected methodSupported in .NET for Windows Store appsProcessResponsePerform processing on each response from the server.
Protected methodSupported in .NET for Windows Store appsSendAsyncSends an HTTP request to the inner handler to send to the server as an asynchronous operation. (Overrides DelegatingHandler.SendAsync(HttpRequestMessage, CancellationToken).)
Public methodSupported in .NET for Windows Store appsToStringReturns a string that represents the current object. (Inherited from Object.)

The actual creation of response messages is delegated to an inner handler. The MessageProcessingHandler is useful if the handler doesn't require asynchronous operations, because operations on request and response messages are fast.

The most common usage is to derive from this class and override the ProcessRequest and ProcessResponse methods.
