[C#/COMMON] 튜플 반환 타입(Tuple Return Type) 사용하기

■ 튜플 반환 타입(Tuple Return Type)을 사용하는 방법을 보여준다.

▶ 예제 코드 (C#)


using System;
using System.Collections.Generic;

List<int> sourceList = new List<int> { 1, 2, 3, 4, 5 };

var result = Calculate(sourceList);

Console.WriteLine($"{result.Count}, {result.Summary}, {result.Average}");
Console.WriteLine($"{result.Item1}, {result.Item2}, {result.Item3}");

#region 계산하기 - Calculate(sourceList)

/// <summary>
/// 계산하기
/// </summary>
/// <param name="sourceList">소스 리스트</param>
/// <returns>카운트, 합계, 평균</returns>
private (int Count, int Summary, double Average) Calculate(List<int> sourceList)
{
    int    count   = 0;
    int    summary = 0;
    double average = 0d;

    foreach(int source in sourceList)
    {
        count++;

        summary += source;
    }

    average = summary / count;

    return (count, summary, average);
}
