When overridden in a descendant class, returns a response to an Internet request.

public:
 virtual System::Net::WebResponse ^ GetResponse();
public virtual System.Net.WebResponse GetResponse ();
abstract member GetResponse : unit -> System.Net.WebResponse
override this.GetResponse : unit -> System.Net.WebResponse
Public Overridable Function GetResponse () As WebResponse

Returns

WebResponse

A WebResponse containing the response to the Internet request.

Exceptions

NotImplementedException

Any attempt is made to access the method, when the method is not overridden in a descendant class.

Examples

The following example sets the Timeout property to 10000 milliseconds. If the timeout period expires before the resource can be returned, a WebException is thrown.

// Create a new WebRequest Object to the mentioned URL.
WebRequest^ myWebRequest = WebRequest::Create( "http://www.contoso.com" );
Console::WriteLine( "\nThe Timeout time of the request before setting is : {0} milliseconds", myWebRequest->Timeout );

// Set the 'Timeout' property in Milliseconds.
myWebRequest->Timeout = 10000;

// This request will throw a WebException if it reaches the timeout limit
// before it is able to fetch the resource.
WebResponse^ myWebResponse = myWebRequest->GetResponse();


         // Create a new WebRequest Object to the mentioned URL.
WebRequest myWebRequest=WebRequest.Create("http://www.contoso.com");
Console.WriteLine("\nThe Timeout time of the request before setting is : {0} milliseconds",myWebRequest.Timeout);

// Set the 'Timeout' property in Milliseconds.
myWebRequest.Timeout=10000;

// This request will throw a WebException if it reaches the timeout limit before it is able to fetch the resource.
         WebResponse myWebResponse=myWebRequest.GetResponse();


   ' Create a new WebRequest Object to the mentioned URL.
   Dim myWebRequest As WebRequest = WebRequest.Create("http://www.contoso.com")
   Console.WriteLine(ControlChars.Cr + "The Timeout time of the request before setting is : {0} milliseconds", myWebRequest.Timeout)

   ' Set the 'Timeout' property in Milliseconds.
myWebRequest.Timeout = 10000

  ' Assign the response object of 'WebRequest' to a 'WebResponse' variable.
   Dim myWebResponse As WebResponse = myWebRequest.GetResponse()

Remarks

Caution

WebRequest, HttpWebRequest, ServicePoint, and WebClient are obsolete, and you shouldn't use them for new development. Use HttpClient instead.

The GetResponse method sends a request to an Internet resource and returns a WebResponse instance. If the request has already been initiated by a call to GetRequestStream, the GetResponse method completes the request and returns any response.

The GetResponse method provides synchronous access to the WebResponse. For asynchronous access, use the BeginGetResponse and EndGetResponse methods.

Note

The WebRequest class is an abstract class. The actual behavior of WebRequest instances at run time is determined by the descendant class returned by the WebRequest.Create method. For more information about default values and exceptions, see the documentation for the descendant classes, such as HttpWebRequest and FileWebRequest.

Note

If a WebException is thrown, use the Response and Status properties of the exception to determine the response from the server.
