// Specify one argument: the name of the host to

   if ( args == nullptr || args->Length != 2 )
   {
      Console::WriteLine( "Specify the URL to receive the request." );
      Environment::Exit( 1 );
   }

   
   HttpWebRequest^ request = dynamic_cast<HttpWebRequest^>(WebRequest::Create( args[ 1 ] ));
   request->CookieContainer = gcnew CookieContainer;
   HttpWebResponse^ response = dynamic_cast<HttpWebResponse^>(request->GetResponse());
   response->Cookies = request->CookieContainer->GetCookies( request->RequestUri );
   
   // Print the properties of each cookie.
   System::Collections::IEnumerator^ myEnum = response->Cookies->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      Cookie^ cook = safe_cast<Cookie^>(myEnum->Current);
      Console::WriteLine( "Cookie:" );
      Console::WriteLine( "{0} = {1}", cook->Name, cook->Value );
      Console::WriteLine( "Domain: {0}", cook->Domain );
      Console::WriteLine( "Path: {0}", cook->Path );
      Console::WriteLine( "Port: {0}", cook->Port );

      Console::WriteLine( "Comment: {0}", cook->Comment );
      Console::WriteLine( "Uri for comments: {0}", cook->CommentUri );
      Console::WriteLine( "Version: RFC {0}", cook->Version == 1 ? (String^)"2109" : "2965" );
      
      // Show the string representation of the cookie.
      Console::WriteLine( "String: {0}", cook );

注釈

CookieContainer プロパティは、この要求に関連付けられた cookie を含む CookieContainer クラスのインスタンスを提供します。The CookieContainer property provides an instance of the CookieContainer class that contains the cookies associated with this request.

既定では、CookieContainernull です。CookieContainer is null by default. GetResponse メソッドによって返される HttpWebResponseCookies プロパティにクッキーが返されるようにするには、CookieContainer オブジェクトをプロパティに割り当てる必要があります。You must assign a CookieContainer object to the property to have cookies returned in the Cookies property of the HttpWebResponse returned by the GetResponse method.

注意

セキュリティ上の理由から、cookie は既定で無効になっています。For security reasons, cookies are disabled by default. Cookie を使用する場合は、CookieContainer プロパティを使用して cookie を有効にします。If you want to use cookies, use the CookieContainer property to enable cookies.
