FieldBuilder.Name 속성

정의

네임스페이스:

System.Reflection.Emit

어셈블리:

System.Reflection.Emit.dll

해당 필드의 이름을 나타냅니다. 이 속성은 읽기 전용입니다.

public:
 virtual property System::String ^ Name { System::String ^ get(); };

public override string Name { get; }

member this.Name : string

Public Overrides ReadOnly Property Name As String

속성 값

String

해당 필드의 이름이 들어 있는 String입니다.
