自定义类：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace CSharp中Dictionary排序方式
{
[Serializable]
public class CustmonizedClass
{
public string stuＮame { get; set; }
public int stuAge { get; set; }
public string stuSex { get; set; }
public double stuScore { get; set; }
}
}
Dictionary<int,自定义类>
按照Dictionary的Key值 升序排序(OrderBy)、降序排序(OrderByDescending)：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace CSharp中Dictionary排序方式
{
public class Program
{
static void Main(string[] args)
{
CustmonizedClass cn1 = new CustmonizedClass();
cn1.stuＮame = "张三";
cn1.stuAge = 18;
cn1.stuSex = "男";
cn1.stuScore = 89.5;
CustmonizedClass cn2 = new CustmonizedClass();
cn2.stuＮame = "李四";
cn2.stuAge = 19;
cn2.stuSex = "男";
cn2.stuScore = 88.5;
CustmonizedClass cn3 = new CustmonizedClass();
cn3.stuＮame = "王五";
cn3.stuAge = 17;
cn3.stuSex = "女";
cn3.stuScore = 89.5;
Dictionary<int, CustmonizedClass> dic1 = new Dictionary<int, CustmonizedClass>();
dic1.Add(3, cn1);
dic1.Add(1, cn2);
dic1.Add(2, cn3);
//上面dic1.Add()故意不按照顺序
Dictionary<int, CustmonizedClass> dic1_SortedByKey = dic1.OrderBy(p=>p.Key).ToDictionary(p => p.Key, o => o.Value);
foreach (KeyValuePair<int, CustmonizedClass> item in dic1_SortedByKey)
{
Console.WriteLine("Key:{0} ; Value: name:{1}, age:{2}, sex:{3}, score:{4} ",
item.Key,item.Value.stuＮame,item.Value.stuAge,item.Value.stuSex,item.Value.stuScore);
}
Console.ReadLine();
}
}
}
Dictionary<int, CustmonizedClass> dic1_SortedByKey = dic1.OrderBy(p=>p.Key).ToDictionary(p => p.Key, o => o.Value);
结果截图：
降序排序：
Dictionary<int, CustmonizedClass> dic1_SortedByKey = dic1.OrderByDescending(p => p.Key).ToDictionary(p => p.Key, o => o.Value);

按照Dictionary的Value值的某个属性 升序排序(OrderBy)、降序排序(OrderByDescending)：

//Value中stuAge属性
