UIPermission.ToXml 方法

定义

创建权限及其当前状态的 XML 编码。

public:
 override System::Security::SecurityElement ^ ToXml();
public override System.Security.SecurityElement ToXml ();
override this.ToXml : unit -> System.Security.SecurityElement
Public Overrides Function ToXml () As SecurityElement

返回

权限的 XML 编码,包括任何状态信息。

示例

下面的代码示例演示 了 方法的行为 ToXml 。 此示例是为 类提供的更大示例的 UIPermission 一部分。

注意

代码示例旨在显示方法的行为,而不是演示其用法。 通常,权限类的方法由安全基础结构使用;它们通常不用于应用程序。


// ToXml creates an XML encoding of the permission and its current state; FromXml reconstructs a
// permission with the specified state from the XML encoding.
void ToFromXmlDemo()
{
    Console::WriteLine("\n**********************  To/From XML() Demo *********************\n");

    UIPermission ^ uiPerm1 = gcnew UIPermission(UIPermissionWindow::SafeTopLevelWindows);
    UIPermission ^ uiPerm2 = gcnew UIPermission(PermissionState::None);
    uiPerm2->FromXml(uiPerm1->ToXml());
    bool result = uiPerm2->Equals(uiPerm1);
    if (result)
        Console::WriteLine("Result of ToFromXml = " + uiPerm2->ToString());
