UIPermission.Union メソッド

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。

名前空間: System.Security.Permissions
アセンブリ: mscorlib (mscorlib.dll 内)
構文

Visual Basic (宣言)

Public Overrides Function
 Union ( _
    target As IPermission _
) As IPermission

Visual Basic (使用法)

Dim instance As UIPermission
Dim target As IPermission
Dim returnValue As IPermission

returnValue = instance.Union(target)

C#

public override IPermission Union (
    IPermission target
)

C++

public:
virtual IPermission^ Union (
    IPermission^ target
) override

J#

public IPermission Union (
    IPermission target
)

JScript

public override function Union (
    target : IPermission
) : IPermission

パラメータ

target

現在のアクセス許可と和集合を持つアクセス許可。これは、現在のアクセス許可と同じ型であることが必要です。

戻り値
現在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新しいアクセス許可。

例外

例外の種類	条件
ArgumentException	target パラメータが null 参照 (Visual Basic では Nothing) ではなく、現在のアクセス許可と同じ型でもありません。

解説

Union を呼び出すと、現在のアクセス許可と指定したアクセス許可の両方が表す操作をすべて表すアクセス許可が作成されます。具体的には、このアクセス許可は、現在のアクセス許可と指定されたアクセス許可の値の UIPermissionWindow と UIPermissionClipboard の最大許容値を表します。

使用例

詳細については、UIPermission クラスのトピックを参照してください。
