KeyValuePair类使用C#将一对值存储在单个列表中。
设置KeyValuePair并添加元素 −
var myList = new List<KeyValuePair<string, int>>(); // adding elements myList.Add(new KeyValuePair<string, int>("Laptop", 20)); myList.Add(new KeyValuePair<string, int>("Desktop", 40)); myList.Add(new KeyValuePair<string, int>("Tablet", 60));
这里是学习如何使用 KeyValuePair 并显示键和值的代码 -
Using System; using System.Collections.Generic; class Program { static void Main() { var myList = new List<KeyValuePair<string, int>>(); // adding elements myList.Add(new KeyValuePair<string, int>("Laptop", 20)); myList.Add(new KeyValuePair<string, int>("Desktop", 40)); myList.Add(new KeyValuePair<string, int>("Tablet", 60)); foreach (var val in myList) { Console.WriteLine(val); } } }
