EnumBuilder クラス

.NET Framework クラス ライブラリ リファレンス

EnumBuilder クラス

列挙型を記述し、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)

<ComVisibleAttribute(True)> _
<ClassInterfaceAttribute(ClassInterfaceType.None)> _
Public NotInheritable Class
 EnumBuilder
    Inherits Type
    Implements _EnumBuilder

Visual Basic (使用法)

Dim instance As EnumBuilder

C#

[ComVisibleAttribute(true)] 
[ClassInterfaceAttribute(ClassInterfaceType.None)] 
public sealed class EnumBuilder : Type, _EnumBuilder

C++

[ComVisibleAttribute(true)] 
[ClassInterfaceAttribute(ClassInterfaceType::None)] 
public ref class EnumBuilder sealed : public
 Type, _EnumBuilder

J#

/** @attribute ComVisibleAttribute(true) */ 
/** @attribute ClassInterfaceAttribute(ClassInterfaceType.None) */ 
public final class EnumBuilder extends Type
 implements _EnumBuilder

JScript

ComVisibleAttribute(true) 
ClassInterfaceAttribute(ClassInterfaceType.None) 
public final class EnumBuilder extends
 Type implements _EnumBuilder
