Source:

NetworkInformationPermission.cs

이 사용 권한과 지정된 사용 권한의 합집합에 해당하는 사용 권한을 만듭니다.

public:
 override System::Security::IPermission ^ Union(System::Security::IPermission ^ target);

public override System.Security.IPermission Union (System.Security.IPermission target);

override this.Union : System.Security.IPermission -> System.Security.IPermission

Public Overrides Function Union (target As IPermission) As IPermission

매개 변수

target

IPermission

현재 사용 권한과 결합할 NetworkInformationPermission 사용 권한입니다.

반환

IPermission

현재 사용 권한 및 지정한 사용 권한의 합을 나타내는 새 사용 권한입니다.

예제

다음 예제에서는 기존 사용 권한 개체의 공용 구조체인 권한 개체를 만듭니다.

System::Net::NetworkInformation::NetworkInformationPermission^ unrestricted = gcnew System::Net::NetworkInformation::NetworkInformationPermission( System::Security::Permissions::PermissionState::Unrestricted );

Console::WriteLine( L"Is unrestricted? {0}", unrestricted->IsUnrestricted() );

System::Net::NetworkInformation::NetworkInformationPermission^ read = gcnew System::Net::NetworkInformation::NetworkInformationPermission( System::Net::NetworkInformation::NetworkInformationAccess::Read );

System::Net::NetworkInformation::NetworkInformationPermission^ copyPermission = dynamic_cast<System::Net::NetworkInformation::NetworkInformationPermission^>(read->Copy());

System::Net::NetworkInformation::NetworkInformationPermission^ unionPermission = dynamic_cast<System::Net::NetworkInformation::NetworkInformationPermission^>(read->Union( unrestricted ));
Console::WriteLine( L"Is subset?{0}", read->IsSubsetOf( unionPermission ) );

System.Net.NetworkInformation.NetworkInformationPermission unrestricted =
    new System.Net.NetworkInformation.NetworkInformationPermission(
        System.Security.Permissions.PermissionState.Unrestricted);

Console.WriteLine("Is unrestricted? " + unrestricted.IsUnrestricted());

System.Net.NetworkInformation.NetworkInformationPermission read =
    new System.Net.NetworkInformation.NetworkInformationPermission(
        System.Net.NetworkInformation.NetworkInformationAccess.Read);
System.Net.NetworkInformation.NetworkInformationPermission copyPermission =
   (System.Net.NetworkInformation.NetworkInformationPermission) read.Copy();
System.Net.NetworkInformation.NetworkInformationPermission unionPermission =
   (System.Net.NetworkInformation.NetworkInformationPermission) read.Union(unrestricted);
Console.WriteLine("Is subset?" + read.IsSubsetOf(unionPermission));

Dim unrestricted As New System.Net.NetworkInformation.NetworkInformationPermission( _
    System.Security.Permissions.PermissionState.Unrestricted)
Console.WriteLine("Is unrestricted? " + unrestricted.IsUnrestricted().ToString())
Dim read As New System.Net.NetworkInformation.NetworkInformationPermission( _ 
    System.Net.NetworkInformation.NetworkInformationAccess.Read)
Dim copyPermission As System.Net.NetworkInformation.NetworkInformationPermission = _
    CType(read.Copy(), System.Net.NetworkInformation.NetworkInformationPermission)
Dim unionPermission As System.Net.NetworkInformation.NetworkInformationPermission = _
    CType(read.Union(unrestricted), System.Net.NetworkInformation.NetworkInformationPermission)
Console.WriteLine("Is subset?" + read.IsSubsetOf(unionPermission).ToString())

설명

메서드는 Union 현재 사용 권한과 지정된 사용 권한으로 표시되는 모든 상태를 나타내는 사용 권한을 반환합니다. 사용 권한을 통과하는 모든 요구는 해당 공용 구조체를 통과합니다.
