Oid クラス

メモ : このクラスは、.NET Framework version 2.0 で新しく追加されたものです。

暗号オブジェクトの識別子を表します。このクラスは継承できません。

名前空間: System.Security.Cryptography
アセンブリ: System (system.dll 内)
構文構文

Visual Basic (宣言)
Public NotInheritable Class
 Oid
Visual Basic (使用法)
Dim instance As Oid
C#
public sealed class Oid

public final class Oid
解説解説

暗号オブジェクト識別子は、値/名前ペアで構成されます。ペアの一方のプロパティを既知の値に設定すると、もう一方のプロパティが自動的に更新され、対応する値に設定されます。たとえば、Value プロパティを "1.3.6.1.5.5.7.3.4" に設定すると、FriendlyName プロパティ (ローカライズ対象) は自動的に "Secure Email" に設定されます。

Oid コンストラクタ (String, String)

メモ : このコンストラクタは、.NET Framework version 2.0 で新しく追加されたものです。

値と表示名を指定して、Oid クラスの新しいインスタンスを初期化します。

名前空間: System.Security.Cryptography
アセンブリ: System (system.dll 内)
構文構文

Visual Basic (宣言)
Public Sub New ( _
    value As String, _
    friendlyName As String _
)
Visual Basic (使用法)
Dim value As String
Dim friendlyName As String

Dim instance As New Oid(value,
 friendlyName)
C#
public Oid (
    string value,
    string friendlyName
)
C++
public:
Oid (
    String^ value, 
    String^ friendlyName
)
J#
public Oid (
    String value, 
    String friendlyName
)
JScript
public function Oid (
    value : String, 
    friendlyName : String
)

パラメータ

value

識別子を示すドット区切りの数値。

friendlyName

識別子の表示名。

解説解説

このコンストラクタを使用して、既存の Oid オブジェクトの値をコピーできます。この OID の値が認識されなければ、value パラメータと friendlyName パラメータが互いに対応しているかどうかが検査されません。これは、アプリケーションでは解釈できても、.NET Framework では認識されないオブジェクト識別子があるためです。
