.NET Framework クラス ライブラリ リファレンス

Cookie.Version プロパティ

Cookie が準拠する HTTP 状態保守のバージョンを取得または設定します。

名前空間: System.Net
アセンブリ: System (system.dll 内)
構文

Visual Basic (宣言)

Public Property Version As
 Integer

Visual Basic (使用法)

Dim instance As Cookie
Dim value As Integer

value = instance.Version

instance.Version = value

C#

public int Version { get;
 set; }

C++

public:
property int Version {
    int get ();
    void set (int value);
}

J#

/** @property */
public int get_Version ()

/** @property */
public void set_Version (int
 value)

JScript

public function get Version
 () : int

public function set Version
 (value : int)

プロパティ値
Cookie が準拠する HTTP 状態保守のバージョン。

解説

既定の Cookie バージョンは Netscape です。値が明示的に 1 に設定されている場合、この Cookie は RFC 2109 に準拠している必要があります。Set-Cookie2 HTTP 応答ヘッダーを受信することにより Cookie が自動的に作成された場合、準拠は RFC 2965 に設定されます。

使用例

応答で返される Cookie のプロパティを表示する例を次に示します。詳細については、Cookie クラスのトピックを参照してください。

Visual Basic

Dim request As HttpWebRequest = CType(WebRequest.Create(args(0)),
 HttpWebRequest)
request.CookieContainer = New CookieContainer()

Dim response As HttpWebResponse = CType(request.GetResponse(),
 HttpWebResponse)



' Print the properties of each cookie.
Dim cook As Cookie
For Each cook In  response.Cookies
    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("Secure: {0}", cook.Secure)
    
    Console.WriteLine("When issued: {0}", cook.TimeStamp)
    Console.WriteLine("Expires: {0} (expired? {1})",
 cook.Expires, cook.Expired)
    Console.WriteLine("Don't save: {0}", cook.Discard)
    Console.WriteLine("Comment: {0}", cook.Comment)
    Console.WriteLine("Uri for comments: {0}", cook.CommentUri)
    Console.WriteLine("Version: RFC {0}", IIf(cook.Version
 = 1, "2109", "2965"))
    
    ' Show the string representation of the cookie.
    Console.WriteLine("String: {0}", cook.ToString())
Next cook

C#

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(args[0]);
request.CookieContainer = new CookieContainer();
        
HttpWebResponse response = (HttpWebResponse) request.GetResponse();



// Print the properties of each cookie.
foreach (Cookie cook in response.Cookies)
{
    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("Secure: {0}", cook.Secure);
 
    Console.WriteLine("When issued: {0}", cook.TimeStamp);
    Console.WriteLine("Expires: {0} (expired? {1})", 
        cook.Expires, cook.Expired);
    Console.WriteLine("Don't save: {0}", cook.Discard);    
    Console.WriteLine("Comment: {0}", cook.Comment);
    Console.WriteLine("Uri for comments: {0}", cook.CommentUri);
    Console.WriteLine("Version: RFC {0}" , cook.Version == 1 ? "2109"
 : "2965");

    // Show the string representation of the cookie.
    Console.WriteLine ("String: {0}", cook.ToString());
}

C++

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( "Secure: {0}", cook->Secure );
   Console::WriteLine( "When issued: {0}", cook->TimeStamp );
   Console::WriteLine( "Expires: {0} (expired? {1})", cook->Expires,
 cook->Expired );
   Console::WriteLine( "Don't save: {0}", cook->Discard );
   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 );
   
}
