Visual Basic (使用法)

Dim instance As Cookie
Dim value As String

value = instance.Path

instance.Path = value

public string Path { get;
 set; }

C++

public:
property String^ Path {
    String^ get ();
    void set (String^ value);
}

/** @property */
public String get_Path ()

/** @property */
public void set_Path (String value)

JScript

public function get Path
 () : String

public function set Path
 (value : String)

解説

Path プロパティは、この Cookie が適用される送信元サーバーの URI のサブセットを指定します。このプロパティが指定されていない場合、この Cookie は送信元サーバーのすべてのページに送信されます。

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

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(args[0]);

 : "2965");

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