When overridden in a descendant class, gets the URI of the Internet resource associated with the request.

public:
 abstract property Uri ^ RequestUri { Uri ^ get(); };
public:
 virtual property Uri ^ RequestUri { Uri ^ get(); };
public abstract Uri RequestUri { get; }
public virtual Uri RequestUri { get; }
member this.RequestUri : Uri
Public MustOverride ReadOnly Property RequestUri As Uri
Public Overridable ReadOnly Property RequestUri As Uri

Property Value

Uri

A Uri representing the resource associated with the request.

Exceptions

NotImplementedException

Any attempt is made to get or set the property, when the property is not overridden in a descendant class.

Examples

The following example checks the RequestUri property to determine the site originally requested.

// Create a new WebRequest object to the mentioned URL.
WebRequest^ myWebRequest = WebRequest::Create( "http://www.contoso.com" );
Console::WriteLine( "\nThe Uri requested is {0}", myWebRequest->RequestUri);
// Assign the response object of 'WebRequest' to a 'WebResponse' variable.
WebResponse^ myWebResponse = myWebRequest->GetResponse();
      // Get the stream containing content returned by the server.
Stream^ streamResponse = myWebResponse->GetResponseStream();
      Console::WriteLine("\nThe Uri that responded to the request is '{0}'",myWebResponse->ResponseUri);
StreamReader^ reader = gcnew StreamReader(streamResponse);
      // Read the content.
String^ responseFromServer = reader->ReadToEnd();
// Display the content.
Console::WriteLine("\nThe HTML Contents received:");
Console::WriteLine (responseFromServer);
// Cleanup the streams and the response.
reader->Close();
streamResponse->Close();
myWebResponse->Close();

      // Create a new WebRequest Object to the mentioned URL.
      WebRequest myWebRequest=WebRequest.Create("http://www.contoso.com");
      Console.WriteLine("\nThe Uri that was requested is {0}",myWebRequest.RequestUri);
      // Assign the response object of 'WebRequest' to a 'WebResponse' variable.
      WebResponse myWebResponse=myWebRequest.GetResponse();
      // Get the stream containing content returned by the server.
      Stream streamResponse=myWebResponse.GetResponseStream();
      Console.WriteLine("\nThe Uri that responded to the WebRequest is '{0}'",myWebResponse.ResponseUri);
StreamReader reader = new StreamReader (streamResponse);
      // Read the content.
string responseFromServer = reader.ReadToEnd ();
// Display the content.
Console.WriteLine("\nThe HTML Contents received:");
Console.WriteLine (responseFromServer);
// Cleanup the streams and the response.
reader.Close ();
streamResponse.Close ();
myWebResponse.Close ();

' Create a new WebRequest Object to the mentioned URL.
Dim myWebRequest As WebRequest = WebRequest.Create("http://www.contoso.com")
Console.WriteLine(ControlChars.Cr + ControlChars.Lf +"The Uri that was requested is {0}", myWebRequest.RequestUri)
' Assign the response object of 'WebRequest' to a 'WebResponse' variable.
Dim myWebResponse As WebResponse = myWebRequest.GetResponse()
      ' Get the stream containing content returned by the server.
Dim streamResponse As Stream = myWebResponse.GetResponseStream()
Console.WriteLine(ControlChars.Cr + ControlChars.Lf + "The Uri that responded to the request is {0}", myWebResponse.ResponseUri)
' Print the HTML contents of the page to the console. 
Dim reader As New StreamReader(streamResponse)
      ' Read the content.
      Dim responseFRomServer As String = reader.ReadToEnd()
' Display the content.
Console.WriteLine(ControlChars.Cr + ControlChars.Lf +"The HTML Contents received:")
Console.WriteLine (responseFromServer)
' Cleanup the streams and the response.
reader.Close ()
streamResponse.Close ()
myWebResponse.Close ()

Remarks

Caution

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

When overridden in a descendant class, the RequestUri property contains the Uri instance that Create method uses to create the request.

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.

Notes to Implementers

RequestUri must contain the original Uri instance passed to the Create(Uri) method. If the protocol is able to redirect the request to a different URI to service the request, the descendant must provide a property to contain the URI that actually services the request
