在我的代码这个棘手的部分以及IM和被卡住暂且这么即时通讯寻求一些帮助。我正在用C＃开发它。这里是我的代码片，它的交易： 方法显示是即时通讯对其他人的问题是正确的。问题输出是错误的，并且与每个循环有关。请看看我的什么输出看起来像现在，什么IM的链接试图使它看起来像请

thanks alot guys the question was answered 

Answer 1

在选择使用.Distinct（）：

var items = (from pair in dictionary order by pair.Value descending select pair).Distinct();

Answer 2

var max = 
    (from pair in dictionary 
    select pair.Value).Max() 
for (int i = max; i > -1; i--) 
{ 
    var items = 
     from pair in dictionary 
     where pair.Value == i 
     select pair.Key; 
    if (items.Count() > 0) 
    { 
     Console.WriteLine("\nWords occuring " + i.ToString() +" times"); 
     int count = 0; 
     foreach(var item in items) 
     { 
      if (count == 4) 
      { 
       Console.WriteLine(""); 
       count = 0; 
      } 
      else 
      { 
       count++; 
      } 
      Console.Write(item + "\t"); 
     } 
    } 
} 

用类似于此的替换display方法中的代码应返回所需的结果。

Answer 3

以下是查询以获得期望的结果

var dict = items.GroupBy(x=>x.Value).ToDictionary(y=> y.Key, y=> String.Join(" ", y.Select(z=>z.Key))); 

要理解上面的查询，请参阅grouping，ToDictionary和String.Join。

以下是您所修改的程序

void Main() 
    { 

     SortedDictionary<string, int> dict =Words(); 
     display(dict); 
     Console.WriteLine(); 
    } 

    private static SortedDictionary<String, int> Words() 
    { 

     SortedDictionary<string, int> dic = new SortedDictionary<string, int>(); 

     String input = "today is Wednesday right and it sucks. today how are you are you a rabbit today"; 
     string[] word = Regex.Split(input, @"\s"); 

     foreach (string current in word) 
     { 
      string wordKey = current.ToLower(); 

      if (dic.ContainsKey(wordKey)) 
      { 
       ++dic[wordKey]; 
      } 
      else 
      { 
       dic.Add(wordKey, 1); 
      } 
     } 
     return dic; 
    } 

    private static void display(SortedDictionary<string, int> dictionary) 
    { 

     var items = from pair in dictionary 
       orderby pair.Value descending 
       select pair; 
     var dict = items.GroupBy(x=>x.Value).ToDictionary(y=> y.Key, y=> String.Join(" ", y.Select(z=>z.Key))); 
      foreach (var item in dict) 
     { 
      Console.WriteLine("Words occurung "+item.Key +" times"); 
      Console.WriteLine("{0}", item.Value); 
     } 

     Console.ReadLine(); 
    } 

输出

Words occurung 3 times 
today 
Words occurung 2 times 
are you 
Words occurung 1 times 
a and how is it rabbit right sucks. wednesday
