在C#字典中添加键值对
要在C#词典中添加键值对，请首先声明一个词典。
IDictionary<int, string> d = new Dictionary<int, string>();
现在，使用KeyValuePair添加元素。
d.Add(new KeyValuePair<int, string>(1, "TVs")); d.Add(new KeyValuePair<int, string>(2, "Appliances")); d.Add(new KeyValuePair<int, string>(3, "Mobile"));
添加元素后，让我们显示键值对。
示例
using System;
using System.Collections.Generic;
public class Demo {
public static void Main() {
IDictionary<int, string> d = new Dictionary<int, string>();
d.Add(new KeyValuePair<int, string>(1, "TVs"));
d.Add(new KeyValuePair<int, string>(2, "Appliances"));
d.Add(new KeyValuePair<int, string>(3, "Mobile"));
d.Add(new KeyValuePair<int, string>(4, "Tablet"));
d.Add(new KeyValuePair<int, string>(5, "Laptop"));
d.Add(new KeyValuePair<int, string>(6, "Desktop"));
d.Add(new KeyValuePair<int, string>(7, "Hard Drive"));
d.Add(new KeyValuePair<int, string>(8, "Flash Drive"));
foreach (KeyValuePair<int, string> ele in d) {
Console.WriteLine("Key = {0}, Value = {1}", ele.Key, ele.Value);
}
}
}输出结果
Key = 1, Value = TVs Key = 2, Value = Appliances Key = 3, Value = Mobile Key = 4, Value = Tablet Key = 5, Value = Laptop Key = 6, Value = Desktop Key = 7, Value = Hard Drive Key = 8, Value = Flash Drive
