分类打印:

var items = from pair in players_Dic
                orderby pair.Value descending
                select pair;

// Display results.
foreach (KeyValuePair<string, int> pair in items)
{
    Debug.Log(pair.Key + " - " + pair.Value);
}

将降序改为升序以改变排序顺序

你可以按值对Dictionary进行排序，并使用下面的代码在Dictionary中获取结果:

Dictionary <<string, string>> ShareUserNewCopy = 
       ShareUserCopy.OrderBy(x => x.Value).ToDictionary(pair => pair.Key,
                                                        pair => pair.Value);                                          

使用LINQ:

Dictionary<string, int> myDict = new Dictionary<string, int>();
myDict.Add("one", 1);
myDict.Add("four", 4);
myDict.Add("two", 2);
myDict.Add("three", 3);

var sortedDict = from entry in myDict orderby entry.Value ascending select entry;

这也为你提供了很大的灵活性，你可以选择前10%，20 - 10%等等。或者，如果您正在使用词频索引进行提前输入，您还可以包括StartsWith子句。

或者为了好玩，你可以使用一些LINQ扩展的优点:

var dictionary = new Dictionary<string, int> { { "c", 3 }, { "a", 1 }, { "b", 2 } };
dictionary.OrderBy(x => x.Value)
  .ForEach(x => Console.WriteLine("{0}={1}", x.Key,x.Value));

所需的命名空间:使用System.Linq;

Dictionary<string, int> counts = new Dictionary<string, int>();
counts.Add("one", 1);
counts.Add("four", 4);
counts.Add("two", 2);
counts.Add("three", 3);

按描述排序:

foreach (KeyValuePair<string, int> kvp in counts.OrderByDescending(key => key.Value))
{
// some processing logic for each item if you want.
}

按Asc排序:

foreach (KeyValuePair<string, int> kvp in counts.OrderBy(key => key.Value))
{
// some processing logic for each item if you want.
}

你可以用:

Dictionary<string, string> dic= new Dictionary<string, string>();
var ordered = dic.OrderBy(x => x.Value);
return ordered.ToDictionary(t => t.Key, t => t.Value);
