获得一个排序字典最简单的方法是使用内置的SortedDictionary类:

//Sorts sections according to the key value stored on "sections" unsorted dictionary, which is passed as a constructor argument
System.Collections.Generic.SortedDictionary<int, string> sortedSections = null;
if (sections != null)
{
    sortedSections = new SortedDictionary<int, string>(sections);
}

sortedSections将包含section的排序版本

字典根据定义是一种无序的关联结构，仅以可哈希的方式包含值和键。换句话说，没有一种可预见的方式来排序一本字典。

作为参考，请阅读这篇来自python语言的文章。

使用VB对SortedDictionary列表进行排序以绑定到ListView控件。NET:

Dim MyDictionary As SortedDictionary(Of String, MyDictionaryEntry)

MyDictionaryListView.ItemsSource = MyDictionary.Values.OrderByDescending(Function(entry) entry.MyValue)

Public Class MyDictionaryEntry ' Need Property for GridViewColumn DisplayMemberBinding
    Public Property MyString As String
    Public Property MyValue As Integer
End Class

XAML:

<ListView Name="MyDictionaryListView">
    <ListView.View>
        <GridView>
            <GridViewColumn DisplayMemberBinding="{Binding Path=MyString}" Header="MyStringColumnName"></GridViewColumn>
            <GridViewColumn DisplayMemberBinding="{Binding Path=MyValue}" Header="MyValueColumnName"></GridViewColumn>
         </GridView>
    </ListView.View>
</ListView>

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.
}

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。
