创建Dictionary的几种方法

//Lued
//创建的时候赋值
Dictionary<int, string> dict1 = new Dictionary<int, string>() { { 0, "fuck!" }, { 1, "fuck the world!" } };
Console.WriteLine("dcit1:");
foreach (var dict in dict1) {
    Console.WriteLine(dict.Key +"---"+dict.Value);
}
Console.WriteLine();
//用Add方法
Dictionary<int, string> dict2 = new Dictionary<int, string>();
dict2.Add(0, "fuck!");
dict2.Add(1, "fuck the world!");
Console.WriteLine("dcit2:");
foreach (var dict in dict2)
{
    Console.WriteLine(dict.Key + "---" + dict.Value);
}
Console.WriteLine();
//用[]下标类似于数组的方法
Dictionary<int, string> dict3 = new Dictionary<int, string>();
dict3[0] = "fuck!";
dict3[1] = "fuck the world!";
Console.WriteLine("dcit3:");
foreach (var dict in dict3)
{
    Console.WriteLine(dict.Key + "---" + dict.Value);
}
Console.WriteLine();
Console.WriteLine("ok!");
Console.ReadKey();
