【C#学习笔记】Dictionary容器使用

using System;
using System.Collections.Generic;

namespace ConsoleApplication
{
class Program
{
static void Main(string[] args)
{
Dictionary<string, int> a = new Dictionary<string, int>();

a.Add("xiaoming", 10);
a["xiaozhang"] = 11;
a.Add("xiaoli", 12);

foreach (KeyValuePair<string, int> i in a)
{
Console.Write(i.Key + ":" + i.Value);
Console.WriteLine();
}
Console.WriteLine();

a.Remove("xiaoming");
foreach (KeyValuePair<string, int> i in a)
{
Console.Write(i.Key + ":" + i.Value);
Console.WriteLine();
}

a.ContainsKey("xiaoli");    //返回bool
a.ContainsValue(11);        //返回bool
int s = a["xiaozhang"];
Console.Write(s);

Console.Read();
}
}
