ISecurityEncodable.ToXml 方法

定義

命名空間:

System.Security

組件:

netstandard.dll, System.Runtime.dll

來源:

ISecurityEncodable.cs

建立安全物件及其當前狀態的 XML 編碼。

public:
 System::Security::SecurityElement ^ ToXml();

public System.Security.SecurityElement? ToXml();

abstract member ToXml : unit -> System.Security.SecurityElement

Public Function ToXml () As SecurityElement

傳回

SecurityElement

安全物件的 XML 編碼，包含任何狀態資訊。

範例

以下程式碼範例示範了該 FromXml 方法的實作。 此程式碼範例是本類別更大範例 ISecurityEncodable 的一部分。

// 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

備註

擴充安全物件的自訂程式碼需要實作 和 ToXmlFromXml 方法，使物件可安全編碼。
