Dictionary学习笔记-嵌套Dictionary的遍历与排序(按Key值)(二)

class Program
{
static void Main()
{

//构造一个嵌套字典
Dictionary<int, Dictionary<int, string>> dicExternal = new Dictionary<int, Dictionary<int, string>>();
for (int i = 90; i > 65; i = i - 5)
{
Dictionary<int, string> dicInternal = new Dictionary<int, string>();
for (int j = i; j > i - 5; j--)
{
char asc = (char)j;
dicInternal.Add(j, asc.ToString());
}
dicExternal.Add(i, dicInternal);
}
//内层字典排序
Dictionary<int, Dictionary<int, string>> T = new Dictionary<int, Dictionary<int, string>>();
foreach (int key in dicExternal.Keys)
{
Dictionary<int, string> dicOrderInter = new Dictionary<int, string>();
dicOrderInter = (from p in dicExternal[key] orderby p.Key select p).ToDictionary(pair => pair.Key, pair => pair.Value);
T.Add(key, dicOrderInter);
}
//外层字典排序
Dictionary<int, Dictionary<int, string>> dicOrderExter = new Dictionary<int, Dictionary<int, string>>();
dicOrderExter = (from p in T orderby p.Key select p).ToDictionary(pair => pair.Key, pair => pair.Value);

//输出排序后的所有内层字典的Value
foreach (int key in dicOrderExter.Keys)
{
foreach (int keyInter in dicOrderExter[key].Keys)
{
Console.WriteLine("key:" + keyInter + ",Value:" + dicOrderExter[key][keyInter].ToString());
}
}
Console.ReadLine();

}
}
