dotPeek - 훌륭한 역어셈블 소스 코드 생성 도구

예를 들어 볼까요? 다음과 같이 자동 속성 코드와 await 호출을 포함한 async 메서드를 정의한 경우,

using System;
using System.Collections.Generic;
using System.Net.Http;
using System.Threading.Tasks;

namespace ClassLibrary1
{
    public class MyType
    {
        public string Name { get; set; }

        public async Task<string> Test()
        {
            HttpClient hc = new HttpClient();
            string text = await hc.GetStringAsync("http://www.naver.com");

            Console.WriteLine(text);

            return text;
        }
    }
}

// 자동 속성의 사용으로 생성된 코드
