리플렉션은 코드에서 유형, 메서드 및 필드의 메타데이터를 설명하는 프로세스입니다. 네임스페이스 System.Reflection을 사용하면 로드된 어셈블리, 클래스, 메서드 및 값 형식과 같은 어셈블리 내의 요소에 대한 데이터를 얻을 수 있습니다. System.Reflection에는 수많은 클래스가 있지만 가장 일반적으로 사용되는 클래스는 Assembly, AssemblyName, ConstructorInfo, MethodInfo, ParameterInfo, EventInfo, PropertyInfo 및 MemberInfo입니다.
예시
static void Main(string[] args){
TypeInfo myType = typeof(TextInfo).GetTypeInfo();
IEnumerable<PropertyInfo> properties = myType.DeclaredProperties;
IEnumerable<MethodInfo> methods = myType.DeclaredMethods;
Console.WriteLine(myType);
Console.WriteLine(properties);
Console.WriteLine(methods);
StringBuilder strBuilder = new StringBuilder();
Console.WriteLine();
strBuilder.Append("The properties are:");
foreach (PropertyInfo p in properties){
strBuilder.Append("\n" + p.Name);
}
strBuilder.Append("\n");
strBuilder.Append("\nThe methods are:");
foreach (MethodInfo m in methods){
strBuilder.Append("\n" + m.Name);
}
Console.WriteLine(strBuilder);
} 출력
