WebRequest.RequestUri WebRequest.RequestUri WebRequest.RequestUri WebRequest.RequestUri Property

定義

派生クラスでオーバーライドされると、要求に関連付けられたインターネット リソースの URI を取得します。When overridden in a descendant class, gets the URI of the Internet resource associated with the request.

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

プロパティ値

要求に関連付けられているリソースを表す UriA Uri representing the resource associated with the request

例外

プロパティが派生クラスでオーバーライドされていないのに、そのプロパティの取得または設定が試行されました。Any attempt is made to get or set the property, when the property is not overridden in a descendant class.

次の例ではRequestUri 、プロパティをチェックして、最初に要求されたサイトを確認します。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 ()

注釈

派生クラスでオーバーライドRequestUri Uriされた場合、プロパティは、メソッドCreateが要求を作成するために使用するインスタンスを格納します。When overridden in a descendant class, the RequestUri property contains the Uri instance that Create method uses to create the request.

注意

WebRequest クラスabstractはクラスです。The WebRequest class is an abstract class. 実行時のインスタンスWebRequestの実際の動作は、 WebRequest.Createメソッドによって返される派生クラスによって決まります。The actual behavior of WebRequest instances at run time is determined by the descendant class returned by the WebRequest.Create method. 既定値と例外の詳細については、「」 HttpWebRequestFileWebRequest「」など、子孫クラスのドキュメントを参照してください。For more information about default values and exceptions, see the documentation for the descendant classes, such as HttpWebRequest and FileWebRequest.

注意 (継承者)

RequestUriには、 Uri メソッドに渡された元のインスタンスが含まれている必要があります。Create(Uri) RequestUri must contain the original Uri instance passed to the Create(Uri) method. プロトコルで要求を別の URI にリダイレクトして要求を処理できる場合、子孫は、実際に要求を処理する URI を格納するプロパティを提供する必要があります。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
