DTO(Data Transfer Object)는 읽기 전용(ReadOnly) 객체입니다. C#에서 class가 아닌 record로 구현해야 합니다.
record는 불변성(immutability), 값 기반 동등성(value equality), with 식을 기본 제공하므로 DTO에 최적입니다.
class 대신 record로 선언합니다sealed class + { get; set; } 패턴을 record + 위치 매개변수(positional parameter) 또는 { get; init; } 패턴으로 변환합니다// DTO를 class로 구현 - 불변성 보장 없음, 보일러플레이트 과다
private sealed class PagedResponse
{
public int Page { get; set; }
public int PageSize { get; set; }
public int TotalCount { get; set; }
public int TotalPages { get; set; }
public EmployeeDto[] Data { get; set; } = [];
}
private sealed class CreatedResponse
{
public int Count { get; set; }
public EmployeeDto[] Data { get; set; } = [];
}
private sealed class EmployeeDto
{
public string Name { get; set; } = "";
public string Email { get; set; } = "";
public string Tel { get; set; } = "";
public DateTime Joined { get; set; }
}
// JSON 역직렬화용 DTO를 class로 구현
private sealed class JsonEmployeeDto
{
public string? Name { get; set; }
public string? Email { get; set; }
public string? Tel { get; set; }
public string? Joined { get; set; }
}
// DTO를 record로 구현 - 불변성 보장, 간결한 코드
