简单介绍一下字典的遍历

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ExampleTest : MonoBehaviour
{
//如何遍历一个字典的四种方式

// Use this for initialization
void Start()
{
Dictionary<string, int> list = new Dictionary<string, int>();
list.Add("LY", 1);
list.Add("YZY", 2);
list.Add("YM", 3);
list.Add("YZLY", 4);

foreach (var item in list)
{
Debug.Log(item.Key + item.Value);
}

//使用KeyValuePair<T,K>
foreach (KeyValuePair<string, int> kv in list)
{
Debug.Log(kv.Key + kv.Value);
}

//通过键的集合取值
foreach (string key in list.Keys)
{
Debug.Log(key + list[key]);
}

//直接取值
foreach (var val in list.Values)
{
Debug.Log(val);
}

//for循环
List<string> test = new List<string>(list.Keys);
for (int i = 0; i < list.Count; i++)
{
Debug.Log(test[i] + list[test[i]]);
}

}
