Codenameプロパティに関して、set時に大文字にする処理を入れてみた。

### 方法

- class Personに以下の変更をする
    - private でcodenameを追加
    - public Codenameのgetとsetを実装。

```
    // Name, Race, Codename
    public class Person
    {
        public bool Checked { get; set; }
        public string Name { get; set; }
        public string Race { get; set; }
        private string codename;
        public string Codename {
            get { return codename; }
            set { codename = value.ToUpper(); }
        }
    }
```

Codenameが大文字になった。

変換以外にも数値のみ入力などの処理を実装できそう。
