我们知道.NET中的Dictionary是键/值对的集合,使用起来也是比较方便,Dictionary也可以用KeyValuePair来迭代遍历,具体如下:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace _02DictionaryIterator
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("开始遍历集合");
            IteratorDictionary();
            Console.ReadKey();
        }

        /// <summary>
        /// 遍历Dictionary集合
        /// </summary>
        private static void IteratorDictionary()
        {
            Dictionary<string, int> dictionary = new Dictionary<string, int>
            {
                {"张三", 1},
                {"李四", 2},
                {"王五", 3},
                {"赵六", 4},
                {"田七", 5}
            };

            foreach (KeyValuePair<string, int> keyValuePair in dictionary)
            {
                Console.WriteLine("key:{0}\tvalue:{1}", keyValuePair.Key, keyValuePair.Value);
            }
        }
    }
}

运行结果如下:
