分割字符串在C＃中使用正则表达式

Question

我有以下内容的文件

aaaaa(fasdfiojasdlfkj) 
213.df(fasdfsadffdfsd) 
53434534535(oipowerier) 
2.3.*12.4(asdfrwer) 

我想有这样的最终名单，

List<string[]> sList = new List<string[]>(); 
sList[0] = new string[]{"aaaaa", "fasdfiojasdlfkj"}; 
sList[1] = new string[]{"213.df", "fasdfsadffdfsd"}; 
sList[2] = new string[]{"53434534535", "oipowerier"}; 
sList[3] = new string[]{"2.3.*12.4", "asdfrwer"}; 

Answer 1

你可以做到这一点没有正则表达式：

var result = stringlist.ConvertAll(x =>x.Split(new char[] {'(',')'}, 
          StringSplitOptions.RemoveEmptyEntries)); 

Answer 2

你不需要Regex这个 - string.Split就够了。

如果你使用它每行：

List<string[]> sList = new List<string[]>(); 
foreach(var line in fileLines) 
{ 
    sList.Add(line.Split(new Char[]{ '(', ')'}, 
       StringSplitOptions.RemoveEmptyEntries)); 
} 

Answer 3

List<string[]> sList = new List<string[]>(); 

MatchCollection matches = Regex.Matches(yourtext, @"([^\(]+)\(([^\)]+)\)"); 

foreach(Match mymatches in matches) 
{ 

    //get the data 
    string firststring = mymatches.Groups[1].Value; 
    string secondstring = mymatches.Groups[2].Value; 

    sList.Add(new string[] {firststring, secondstring}); 
} 

虽然没有测试....
