EnumBuilder.DefineLiteral(String, Object) 메서드

정의

네임스페이스:

System.Reflection.Emit

어셈블리:

System.Reflection.Emit.dll

Source:

EnumBuilder.cs

지정된 상수 값을 사용하여 열거형의 명명된 정적 필드를 정의합니다.

public:
 System::Reflection::Emit::FieldBuilder ^ DefineLiteral(System::String ^ literalName, System::Object ^ literalValue);

public System.Reflection.Emit.FieldBuilder DefineLiteral (string literalName, object? literalValue);

member this.DefineLiteral : string * obj -> System.Reflection.Emit.FieldBuilder

Public Function DefineLiteral (literalName As String, literalValue As Object) As FieldBuilder

매개 변수

literalName

String

정적 필드의 이름입니다.

literalValue

Object

리터럴의 상수 값입니다.

반환

FieldBuilder

정의된 필드입니다.

예제

다음 코드 예제에서는 를 사용하여 EnumBuilder동적 어셈블리 내에서 열거형을 생성하는 방법을 보여 줍니다. 이 예제에서는 의 기본 형식Int32을 사용하여 라는 Elevation열거형을 정의하고 값이 0High인 와 값이 1인 두 개의 요소를 Low만듭니다. 형식을 만든 후 어셈블리는 이름으로 TempAssembly.dll저장됩니다. Ildasm.exe(IL 디스어셈블러)를 사용하여 이 어셈블리의 내용을 검사할 수 있습니다.

참고

.NET Framework 버전 2.0 이전에는 이 코드 예제가 올바른 열거형을 생성하지 않습니다.

참고

.NET Framework 버전 1.0 및 1.1에서는 요소가 열거형 형식이 아닌 형식 Int32 인 열거형을 내보내므로 를 사용하여 TypeBuilderEnumBuilder 열거형을 정의해야 합니다. .NET Framework 버전 2.0 EnumBuilder 에서는 요소가 올바른 형식의 열거형을 내보낸다.
