Dictionary排序

对一个Dictionary<TKey, TValue>进行排序可以用LINQ：

Dictionary<string, string> MyDictionary = new Dictionary<string, string>();

1、键排序

MyDictionary = (from entry in MyDictionary 
                                     orderby entry.Key ascending
                                     select entry).ToDictionary(pair => pair.Key, pair => pair.Value);

 

2、值排序

MyDictionary = (from entry in MyDictionary 
                                     orderby entry.Value ascending
                                     select entry).ToDictionary(pair => pair.Key, pair => pair.Value);
