Help us understand the problem. What are the problem?

More than 5 years have passed since last update.

C#でRubyっぽいデバッグ表示(Dictionary編)

前回からの続き。

Dictionary (Rubyでいう所のHash)

Rubyだとこう

hash.rb
dict = {aaa:1, bbb:2, ccc:3}
p dict

C#だとこんな感じになる

Dict.cs
using System;
using System.Collections.Generic;
using System.Linq;

var dict = new Dictionary<string, int>() {
    {"aaa", 1},
    {"bbb", 2},
    {"ccc", 3},
};
Console.WriteLine("{" + String.Join(", ", from v in dict select v.Key + "=>" + v.Value) + "}");

シンボルが文字列になっている以外はほぼ同じ。

{:aaa=>1, :bbb=>2, :ccc=>3}    (Ruby)
{aaa=>1, bbb=>2, ccc=>3}       (C#)

おまけ: Rubyでpinspectを使わずに自力で書く場合

jiriki.rb
puts "{" + dict.map{|key,value| "#{key}=>#{value}"}.join(", ") + "}"```
