例

protected override SecurityToken GetTokenCore(TimeSpan timeout)

    // Create a SamlSecurityToken from the provided assertion
    SamlSecurityToken samlToken = new SamlSecurityToken(assertion);

    // Create a memory stream to write the serialized token into
    // Use an initial size of 64Kb
    MemoryStream s = new MemoryStream(UInt16.MaxValue);

    // Create an XmlWriter over the stream
    XmlWriter xw = XmlWriter.Create(s);

    // Write the SamlSecurityToken into the stream
    ser.WriteToken(xw, samlToken);

    // Seek back to the beginning of the stream
    s.Seek(0, SeekOrigin.Begin);

    // Load the serialized token into a DOM
    XmlDocument dom = new XmlDocument();

    // Create a KeyIdentifierClause for the SamlSecurityToken

注釈

GetTokenCore メソッドがオーバーライドされていて、トークン パラメーターに渡したセキュリティ トークンを取得できない場合、SecurityTokenException 例外をスローします。

クライアントが SOAP メッセージを送信し、セキュリティ トークンが要求される場合、GetToken メソッドが ClientCredentials クラスにより呼び出されます。

GetToken メソッドは GetTokenCore メソッドを呼び出します。
