EnumBuilder Class

Describes and represents an enumeration type.

Namespace: System.Reflection.Emit
Assembly: mscorlib (in mscorlib.dll)

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

The following code sample demonstrates the construction of an enumeration within a dynamic assembly, using EnumBuilder.
