WebRequest.RequestUri Property


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

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

Public Overridable ReadOnly Property RequestUri As Uri

Property Value

Type: System.Uri

A Uri representing the resource associated with the request

Exception Condition

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

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


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 Inheritors:

RequestUri must contain the original Uri instance passed to the Create 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

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

   ' 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 ()
