C# Dictionary 的几种遍历方法

 Dictionary<string, int> list = new Dictionary<string, int>();

 

        list.Add("d", 1);

//3.0以上版本

foreach (var item in list)

    {

        Console.WriteLine(item.Key + item.Value);

    }

    //KeyValuePair<T,K>

    foreach (KeyValuePair<string, int> kv in list)

    {

        Console.WriteLine(kv.Key + kv.Value);

    }

//通过键的集合取

foreach (string key in list.Keys)

    {

        Console.WriteLine(key + list[key]);

    }

//直接取值

foreach (int val in list.Values)

{

    Console.WriteLine(val);

} 

//非要采用for的方法也可

 List<string> test = new List<string>(list.Keys);

 

        for (int i = 0; i < list.Count; i++)

        {

            Console.WriteLine(test[i] + list[test[i]]);

        }
