如何使用linq删除列表中的特殊字符集前缀 [英] How to remove special character set prefix in list using linq

问题描述

大家好， 

Hi All, 

请帮我删除下面字符串列表中的特殊字符集前缀。 

Please help me to remove special character set prefix in below string list here. 

我在这里有以下列表。 

i have below list here. 

 List<string> removalPattern = new List<string>();
            removalPattern.Add(@"[__]");
            string studentInfo = "[__] Student Attendance \n[__] Student Lunch Time\n(**) Parents Meeting Date \n[__] Student Play time\n[__] Student Library time, \n(**) Parents Observation \n";
            var StudentList = Regex.Split(studentInfo, "\n").Where(s => s.Contains(removalPattern[0]) && s != string.Empty).ToArray();

$'b $ b

'StudentList'我得到的每个字符串都带有"[__]"字首。我不需要这个前缀。请帮我删除列表中每个字符串的前缀。

in 'StudentList' i am getting each string with "[__]" prefix. i don't need this prefix. please help me to remove this prefix for each string in list.

谢谢，

Chandu

推荐答案

要从字符串前面删除任意字符，请使用
TrimStart 。要从后面删除，请使用
TrimEnd 。要从两者中删除，请使用
修剪。

To remove an arbitrary character from the front of a string use TrimStart. To remove from the back use TrimEnd. To remove from both use Trim.

var studentList = from s in Regex.Split(...)
                  select s.TrimStart('_');
