如何对列表进行排序< keyvaluepair>按字母顺序排列 [英] How to sort the list<keyvaluepair> in alphabetical order

问题描述

我有一个列表

List<KeyValuePair<int, NoNexusCounterparty>> listcps = noNexusCpsdict.ToList();

NoNexusCounterparty是一个包含交易对手列表的类对象。

如何按字母顺序对此列表进行排序。



我的尝试：



listcps = listcps.Sort （）;



无效..

NoNexusCounterparty is a class object which contains list of counterparties.
How to sort this list by alphabetical order.

What I have tried:

listcps = listcps.Sort();

not working..

推荐答案

尝试使用OrderBy：

Try using OrderBy:

List<KeyValuePair<int, string>> myList = new List<KeyValuePair<int, string>>();
myList.Add(new KeyValuePair<int,string>(9, "Nine"));
myList.Add(new KeyValuePair<int,string>(1, "One"));
myList.Add(new KeyValuePair<int,string>(3, "Three"));
myList = myList.OrderBy(kvp => kvp.Key).ToList();
foreach (var kvp in myList) Console.WriteLine("{0}:{1}", kvp.Key, kvp.Value);
myList = myList.OrderBy(kvp => kvp.Value).ToList();
foreach (var kvp in myList) Console.WriteLine("{0}:{1}", kvp.Key, kvp.Value);

你会得到：

You will get:

1:One
3:Three
9:Nine

和

And

9:Nine
1:One
3:Three

你的意思是不工作？请查看下面的代码段

What you mean by Not working ? check out below snippet

var New1 = EmpList.OrderBy(z => z.Age).ToList();

其中New1是List< employee> ;.

EmpList是List< employee>的变量。

z是Employee类型的变量。

where New1 is a List<employee>.
EmpList is variable of a List<employee>.
z is a variable of Employee type.
