.NET Framework Class Library
WebResponse Class

Provides a response from a Uniform Resource Identifier (URI). This is an abstract class.

Namespace:  System.Net
Assembly:  System (in System.dll)
Syntax
Visual Basic (Declaration) 
<SerializableAttribute> _
Public MustInherit Class WebResponse _
    Inherits MarshalByRefObject _
    Implements ISerializable, IDisposable
Visual Basic (Usage) 
Dim instance As WebResponse
C# 
[SerializableAttribute]
public abstract class WebResponse : MarshalByRefObject, 
    ISerializable, IDisposable
Visual C++ 
[SerializableAttribute]
public ref class WebResponse abstract : public MarshalByRefObject, 
    ISerializable, IDisposable
JScript 
public abstract class WebResponse extends MarshalByRefObject implements ISerializable, IDisposable
Remarks

The WebResponse class is the abstract base class from which protocol-specific response classes are derived. Applications can participate in request and response transactions in a protocol-agnostic manner using instances of the WebResponse class while protocol-specific classes derived from WebResponse carry out the details of the request.

Client applications do not create WebResponse objects directly; they are created by calling the GetResponse method on a WebRequest instance.

Notes to Inheritors:

When you inherit from WebResponse, you must override the following members: ContentLength, ContentType, GetResponseStream, ResponseUri, and Headers.
Examples

The following example creates a WebResponse instance from a WebRequest.

Visual Basic 
' Initialize the WebRequest.
Dim myRequest As WebRequest = WebRequest.Create("http://www.contoso.com")

' Return the response. 
Dim myResponse As WebResponse = myRequest.GetResponse()

' Code to use the WebResponse goes here.
' Close the response to free resources.
myResponse.Close()
C# 
// Initialize the WebRequest.
WebRequest myRequest = WebRequest.Create("http://www.contoso.com");

// Return the response. 
WebResponse myResponse = myRequest.GetResponse();

// Code to use the WebResponse goes here.

// Close the response to free resources.
myResponse.Close();
Visual C++ 
// Initialize the WebRequest.
WebRequest^ myRequest = WebRequest::Create( "http://www.contoso.com" );

// Return the response. 
WebResponse^ myResponse = myRequest->GetResponse();

// Code to use the WebResponse goes here.

// Close the response to free resources.
myResponse->Close();
CPP_OLD 
// Initialize the WebRequest.
WebRequest* myRequest = WebRequest::Create(S"http://www.contoso.com");

// Return the response. 
WebResponse* myResponse = myRequest->GetResponse();

// Code to use the WebResponse goes here.

// Close the response to free resources.
myResponse->Close();
