首先,添加元素-
IDictionary<int, int> d = new Dictionary<int, int>(); d.Add(1,97); d.Add(2,89); d.Add(3,77); d.Add(4,88);
现在,获取密钥-
List<int> myList = new List<int>(d.Keys);
迭代-
foreach (int k in myList) { Console.WriteLine("{0}, {1}", k, d[k]); }
以下是一个例子-
using System; using System.Collections.Generic; public class Demo { public static void Main() { IDictionary < int, int > d = new Dictionary < int, int > (); d.Add(1, 97); d.Add(2, 89); d.Add(3, 77); d.Add(4, 88); List < int > myList = new List < int > (d.Keys); foreach(int k in myList) { Console.WriteLine("{0}, {1}", k, d[k]); } } }
输出结果
1, 97 2, 89 3, 77 4, 88
