Unity/Csharp/配列のソースを表示

==配列宣言==
 int[] nums;
 float[] f;
 Vector3[] v;
 GameObject[] gameObjects;

==数字配列宣言＆入力==
 int[] nums = {10,20,30,40,50,60,70,80,90,100};
or
 int[] nums = new int[10];
 nums[0] = 10;
 nums[1] = 20;
 Debug.Log(nums[1]); // 20

==文字列配列宣言＆入力==
 string[] names = new string[] { "taro", "jiro", "saburo" };
 Debug.Log(names[1]); // jiro

==クラスリスト==
クラス例
<pre>
class Car
{
    public string name;
    public int value;
    public Car(string name, int value)
    {
        this.name = name;
        this.value = value;
    }
}
</pre>
クラスリスト例
 List<Car> cars = new List<Car>();
 cars.Add( new Car("Lexas", 50));

==クラスディクショナリ==
 Dictionary<string, Car> cars = new Dictionary<string, Car>();
 Car bg1 = new Car("Lexas", 50);
 Car bg2 = new Car("Rx8", 100);
 cars.Add("Lexas", bg1);
 cars.Add("Rx8", bg2);
 Car car = cars["Lexas"];

==ディクショナリをenumキーで==
 Dictionary<HogeType, Button> enumDict = new Dictionary<HogeType, Button>();

==ディクショナリforeach==
 foreach(KeyValuePair<HogeType, Button> pair in enumDict){
  Debug.Log (pair.Key + " " + pair.Value);
 }

==ディクショナリのキーの存在判定==
<pre>
if (cars.ContainsKey("Lexas")) {
    // 存在するとき
}
</pre>

==TryGetValueを使うとき==
<pre>
Car carvalue = null;
cars.TryGetValue("Lexas", out carvalue);
</pre>

==List<string>に新規で追加==
 List<string> names = new List<string> { "taro", "jiro", "saburo" };

==List<string>からstring[]へ==
 List<string> words = new List<string>();
 words.Add("taro");
 words.Add("jiro");
 words.Add("saburo");
 string[] wordStrings = words.ToArray();

==string[]からList<string>へ==
 string[] wordStrings = {"taro","jiro","saburo"};
 List<string> list = new List<string>(wordStrings);

==Listの3番目に入れる==
 list.InsertRange(3, "saburo");

==Listの3番目のデータ取得==
 string name = list[2]; // 3 - 1

==先頭に追加==
 List<string> names = new List<string>();
 names.Insert(0, "taro");

==順番逆順に==
 int[] nums = new int[] { 1, 2, 3, 4 };
 nums.Reverse(); // 参照渡しとなり戻り値はvoid

==配列に文字数字が含まれてるか確認==
 List<string> names = new List<string>();
 if (!names.Contains(name)) {
 }

 List<int> nums = new List<int>();
 if (!nums.Contains(num)) {
 }

==配列シャッフル==
<pre>
public static List<int> Shuffle(List<int> list)
{
        for (int i = list.Count - 1; i > 0; i--)
        {
            int j = Random.Range(0, i + 1);
            var tmp = list[i];
            list[i] = list[j];
            list[j] = tmp;
        }
        return list;
}
</pre>

==検索==
<pre>
string[] src = {"taro", "jiro", "saburo"};
var list = new List<string>();
list.AddRange(src);
string item = "jiro";
int num = list.IndexOf(item);
if (num > -1) {
    Debug.Log("ari");
}
</pre>

==配列の最初から削除==
<pre>
List<string> hoges = new List<string>();
hoges.Add("taro");
hoges.Add("jiro");
hoges.Add("saburo");
for (int a = 0; a <= 2; a++)
{
    Debug.Log("hoge=" + hoges[0]);
    hoges.Remove(hoges[0]);
}
Debug.Log("count=" + hoges.Count);
</pre>
出力
<pre>
hoge=taro
hoge=jiro
hoge=saburo
count=0
</pre>

==配列を,区切りで文字列に==
 List<string> words = new List<string>();
 words.Add("taro");
 words.Add("jiro");
 words.Add("saburo");
 string[] wordStrings = words.ToArray();
 Debug.Log(String.Join(",", wordStrings)); // taro,jiro,saburo
