建立安全物件及其目前狀態的 XML 編碼方式。
public:
System::Security::SecurityElement ^ ToXml();C#
public System.Security.SecurityElement? ToXml();C#
public System.Security.SecurityElement ToXml();abstract member ToXml : unit -> System.Security.SecurityElementPublic Function ToXml () As SecurityElement安全物件的 XML 編碼方式，包含所有狀態資訊。
下列程式代碼範例示範如何實作 FromXml 方法。 此程式代碼範例是針對 類別提供的較大範例的 ISecurityEncodable 一部分。
// 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;
}

End Function 'ToXml
擴充安全性物件的自定義程式碼需要實 ToXml 作 和 FromXml 方法來讓對象成為安全性可編碼。
