ConstructorBuilder クラス

動的クラスのコンストラクタを定義および表現します。

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

Visual Basic (宣言)

<ClassInterfaceAttribute(ClassInterfaceType.None)> _
<ComVisibleAttribute(True)> _
Public NotInheritable Class
 ConstructorBuilder
    Inherits ConstructorInfo
    Implements _ConstructorBuilder

Visual Basic (使用法)

Dim instance As ConstructorBuilder

[ClassInterfaceAttribute(ClassInterfaceType.None)] 
[ComVisibleAttribute(true)] 
public sealed class ConstructorBuilder : ConstructorInfo,
 _ConstructorBuilder

C++

[ClassInterfaceAttribute(ClassInterfaceType::None)] 
[ComVisibleAttribute(true)] 
public ref class ConstructorBuilder sealed
 : public ConstructorInfo, _ConstructorBuilder

/** @attribute ClassInterfaceAttribute(ClassInterfaceType.None) */ 
/** @attribute ComVisibleAttribute(true) */ 
public final class ConstructorBuilder extends
 ConstructorInfo implements _ConstructorBuilder

JScript

ClassInterfaceAttribute(ClassInterfaceType.None) 
ComVisibleAttribute(true) 
public final class ConstructorBuilder extends
 ConstructorInfo implements _ConstructorBuilder

解説

メモ
このクラスに適用される HostProtectionAttribute 属性の Resources プロパティの値は、MayLeakOnAbort です。HostProtectionAttribute は、デスクトップアプリケーション (一般的には、アイコンをダブルクリック、コマンドを入力、またはブラウザに URL を入力して起動するアプリケーション) には影響しません。詳細については、HostProtectionAttribute クラスのトピックまたは「SQL Server プログラミングとホスト保護属性」を参照してください。

ConstructorBuilder を使用して、MSIL (Microsoft Intermediate Language) のコンストラクタを完全に記述します。名前、属性、シグネチャ、およびコンストラクタ本体が含まれます。TypeBuilder クラスと組み合わせて使用され、実行時にクラスを作成します。DefineConstructor を呼び出して、ConstructorBuilder のインスタンスを取得します。

ConstructorBuilder の実際の使用方法を次のコード例に示します。
