C# 함수의 값 반환

Question

.CS 파일에 함수가 있습니다. 내가 아래 함수에서 값을 반환하는 방법 (같은 프로젝트에서 두 파일)

을 파일을 .aspx.cs하는 기능에 가져온 많은 값을 반환하려면 (이하 .CS 파일의 코드입니다) :

옹호자, jjj, tyear, 올해, petitioner1, resp1, sb 등을 전달하고 싶습니다. 어떻게해야합니까?

Answer 1

캡슐화 새로운 유형의 관련 모든 값, 그리고 메소드의 반환을 그 타입의 인스턴스.

아, 그리고 같은 거대한 방법을 피하기 위해 시도 - 그들은 단지 하나 개의 값을 반환 등

Answer 2

메서드에서 둘 이상의 값을 반환하려면 클래스를 만들어야합니다. 예를 들어

:

public class Product 
{ 
    int Id { get; set;} 
    string Name { get; set;} 
    double Value { get; set;} 
} 

그리고 당신은 당신의 방법에서 제품을 반환 할 때

public Product GetProduct(string Id) 
{ 
    Product product; 
    // load product here 
    return product; 
} 

Answer 3

기능을 테스트 가독성을 위해 악몽이야. 여러 개의 반환 값에 "out"또는 "ref"매개 변수를 사용하십시오.
