C#中的Orderby子句
C#中使用orderby根据特定顺序按指定字段对集合中的元素进行排序。顺序可以是升序或降序。
以下是我们的元素列表-
List<string> myList = new List<string>();
//添加元素
myList.Add("iOS by Apple");
myList.Add("Android by Google");
myList.Add("Symbian by Nokia");现在，使用Orderby以降序对元素进行排序-
var myLen = from element in myList orderby element.Length descending select element;
以下是完整的代码-
示例
using System;
using System.Collections.Generic;
using System.Linq;
class Demo {
static void Main() {
List<string> myList = new List<string>();
myList.Add("iOS by Apple");
myList.Add("Android by Google");
myList.Add("Symbian by Nokia");
var myLen = from element in myList
orderby element.Length descending
select element;
Console.WriteLine("Descending order...");
foreach (string str in myLen) {
Console.WriteLine(str);
}
}
}输出结果
Descending order... Android by Google Symbian by Nokia iOS by Apple
