C#集合Dictionary中按值的排序

C#集合Dictionary中按值的降序排列

static void Main(string[] args)

{

           
Dictionary<string, int> dt = new
Dictionary<string, int>();

           
dt.Add("美丽",2);

           
dt.Add("校园",1);

           
dt.Add("大学",3);

         
var result1 = from pair in dt select
pair;
           
foreach (KeyValuePair<string, int>
pair in result1)

           
{

               
Console.WriteLine(pair.Key.ToString() + " " +
pair.Value.ToString());

           
}

           
Console.WriteLine();

var result2 = from pair in dt orderby pair.Value select
pair;
           
foreach (KeyValuePair<string, int>
pair in result2)

           
{

               
Console.WriteLine(pair.Key.ToString()+"
"+pair.Value.ToString());

           
}

           
Console.WriteLine();

var result3 = from pair in dt orderby pair.Value descending select
pair;
           
foreach (KeyValuePair<string, int>
pair in result3)

           
{

               
Console.WriteLine(pair.Key.ToString() + " " +
pair.Value.ToString());

           
}

           
Console.Read();

    }

结果输出：
