C#字串陣列中含數字時的排序

遇到這個問題時,從論壇看到的,放到這來做個記錄!
有個array:
string[333] fileList = {"list_1.htnl","list_10.html","list_100.html","list_101.html"......,"list_109.html","list_11.html"......}
意思就是,字串預設的排序並不是按照這種最末尾的數字排序的。我想要生成排序為這樣的陣列.
string[333] fileList = {"list_1.htnl","list_2.html","list_3.html","list_4.html"......,"list_100.html","list_101.html"......}
就是排序是按照最末尾的那個數字的大小來排序。這個數字是遞增的。1---333。
解決方法:
void Main() { string[] fileList =new string[] {"list_1.htnl","list_10.html","list_100.html","list_111.html","list_109.html","list_11.html"}; fileList= fileList.OrderBy(s =>int.Parse( Regex.Match(s, @"\d+").Value)).ToArray(); foreach (string s in fileList) { Console.WriteLine(s); } } /* 結果: list_1.htnl list_10.html list_11.html list_100.html list_109.html list_111.html /*
使用Regex類需要引用名稱空間:using System.Text.RegularExpressions;
