このアクセス許可と指定したアクセス許可の和集合を表すアクセス許可を作成します。

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

パラメーター

target
IPermission

現在のアクセス許可と結合する NetworkInformationPermission アクセス許可。

戻り値

IPermission

現在のアクセス許可と指定されたアクセス許可の和集合を表す新しいアクセス許可。

例

次の例では、既存のアクセス許可オブジェクトの和集合であるアクセス許可オブジェクトを作成します。

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())

注釈

メソッドは Union 、現在のアクセス許可と指定したアクセス許可の両方で表されるすべての状態を表すアクセス許可を返します。 いずれかのアクセス許可を渡す要求は、その共用体を通過します。
