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);                                          

环顾四周，使用一些c# 3.0特性，我们可以这样做:

foreach (KeyValuePair<string,int> item in keywordCounts.OrderBy(key=> key.Value))
{ 
    // do something with item.Key and item.Value
}

这是我见过的最干净的方法，类似于Ruby处理散列的方法。

下面的代码片段按值对Dictionary进行排序。

代码首先创建一个字典，然后使用OrderBy方法对条目进行排序。

public void SortDictionary()  
{  
  
    // Create a dictionary with string key and Int16 value pair  
    Dictionary<string, Int16> AuthorList = new Dictionary<string, Int16>();  
    AuthorList.Add("Mahesh Chand", 35);  
    AuthorList.Add("Mike Gold", 25);  
    AuthorList.Add("Praveen Kumar", 29);  
    AuthorList.Add("Raj Beniwal", 21);  
    AuthorList.Add("Dinesh Beniwal", 84);   
  
    // Sorted by Value  
  
    Console.WriteLine("Sorted by Value");  
    Console.WriteLine("=============");  
    foreach (KeyValuePair<string, Int16> author in AuthorList.OrderBy(key => key.Value))  
    {  
        Console.WriteLine("Key: {0}, Value: {1}", author.Key, author.Value);  
    }  
} 

你可以用:

var ordered = dict.OrderBy(x => x.Value).ToDictionary(x => x.Key, x => x.Value);

最好的方法:

var list = dict.Values.OrderByDescending(x => x).ToList();
var sortedData = dict.OrderBy(x => list.IndexOf(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.
}
