C# 中的 KeyValuePair 类用于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>>();
// 添加元素
myList.Add(new KeyValuePair<string, int>("Laptop>, 20));
myList.Add(new KeyValuePair<string, int>("Desktop>, 40));
myList.Add(new KeyValuePair<string, int>("Tablet>, 60));
以下代码用于学习如何使用 KeyValuePair 并显示键和值 −
示例
Using System;
using System.Collections.Generic;
class Program {
static void Main() {
var myList = new List<KeyValuePair<string, int>>();
// 添加元素
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);
}
}
}
