C#orderby关键字
使用orderbyleyword对列表进行升序或降序排序。
以下是列表-
List<string> myList = new List<string>(); myList.Add("truck"); myList.Add("bus"); myList.Add("bicycle"); myList.Add("motorbike");
现在让我们以降序对列表进行排序-
myLen = from element in myList orderby element.Length descending select element;
这是完整的代码-
示例
using System; using System.Collections.Generic; using System.Linq; class Demo { static void Main() { List<string> myList = new List<string>(); myList.Add("truck"); myList.Add("bus"); myList.Add("bicycle"); myList.Add("motorbike"); var myLen = from element in myList orderby element.Length select element; Console.WriteLine("Ascending order..."); foreach (string str in myLen){ Console.WriteLine(str); } 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
Ascending order... bus truck bicycle motorbike Descending order... motorbike bicycle truck bus
