Przykłady

Poniższy przykład kodu przedstawia implementację FromXml metody. Ten przykład kodu jest częścią większego przykładu podanego ISecurityEncodable dla klasy.

    // Produce XML from the permission's fields.
public:
    virtual SecurityElement^ ToXml() override
    {
        // These first three lines create an element with the required format.
        SecurityElement^ element = gcnew SecurityElement("IPermission");
        // Replace the double quotation marks () 
        // with single quotation marks ()
        // to remain XML compliant when the culture is not neutral.
        element->AddAttribute("class", 
            GetType()->AssemblyQualifiedName->Replace('\"', '\''));
        element->AddAttribute("version", "1");

        if (!specifiedAsUnrestricted)
        {
            element->AddAttribute("Flags", 
                Enum::Format(SoundPermissionState::typeid, stateFlags, "G"));
        }   
        else
        {
            element->AddAttribute("Unrestricted", "true");
        }
        return element;
    }

// Produce XML from the permission's fields.
public override SecurityElement ToXml()
{
    // These first three lines create an element with the required format.
    SecurityElement e = new SecurityElement("IPermission");
    // Replace the double quotation marks ("") with single quotation marks ('')
    // to remain XML compliant when the culture is not neutral.
    e.AddAttribute("class", GetType().AssemblyQualifiedName.Replace('\"', '\''));
    e.AddAttribute("version", "1");

    if (!m_specifiedAsUnrestricted)
        e.AddAttribute("Flags", Enum.Format(typeof(SoundPermissionState), m_flags, "G"));
    else
        e.AddAttribute("Unrestricted", "true");
    return e;
}

' Produce XML from the permission's fields.
Public Overrides Function ToXml() As SecurityElement
    ' These first three lines create an element with the required format.
    Dim e As New SecurityElement("IPermission")
    ' Replace the double quotation marks ("") with single quotation marks ('')
    ' to remain XML compliant when the culture is not neutral.
    e.AddAttribute("class", [GetType]().AssemblyQualifiedName.Replace(ControlChars.Quote, "'"c))
    e.AddAttribute("version", "1")

    If Not m_specifiedAsUnrestricted Then
        e.AddAttribute("Flags", [Enum].Format(GetType(SoundPermissionState), m_flags, "G"))
    Else
        e.AddAttribute("Unrestricted", "true")
    End If
    Return e

End Function 'ToXml

Uwagi

Niestandardowy kod, który rozszerza obiekty zabezpieczeń, musi zaimplementować ToXml metody i FromXml , aby obiekty zabezpieczeń można było enododable.
