C#中的键值对
KeyValuePair类使用C#在单个列表中存储一对值。
设置KeyValuePair并添加元素-
var myList = new List>(); //添加元素 myList.Add(new KeyValuePair ("Laptop", 20)); myList.Add(new KeyValuePair ("Desktop", 40)); myList.Add(new KeyValuePair ("Tablet", 60));
这是学习如何使用KeyValuePair并显示键和值的代码-
示例
Using System;
using System.Collections.Generic;
class Program {
static void Main() {
var myList = new List>();
//添加元素
myList.Add(new KeyValuePair("Laptop", 20));
myList.Add(new KeyValuePair("Desktop", 40));
myList.Add(new KeyValuePair("Tablet", 60));
foreach (var val in myList) {
Console.WriteLine(val);
}
}
}
