# How to split a string stored in list<*> , then insert to same list using linq style or lambda ?

I have Writen o [code](https://yourviews.mindstick.com/view/85458/alan-turing-the-mastermind-behind-cracking-the-enigma-code-during-world-war-ii) using [linq](https://www.mindstick.com/articles/12007/language-integrated-query-linq-queries)

[var](https://www.mindstick.com/forum/33920/what-is-different-var-and-dynamic-types-in-c-sharp) [result](https://www.mindstick.com/blog/12011/advantages-of-getting-result-oriented-seo-from-an-agency)=from m in driver_list [select](https://www.mindstick.com/forum/160534/orderby-then-select-vs-select-then-orderby-performance)(m.Email,m.LisancePlate)

My code [Output](https://www.mindstick.com/interview/34427/explain-the-output-in-angular) is like this

sample1@company.com;sample2@company.com----34 KZ 7898 sample3@company.com;sample2@company.com---- 34 TZK 6785

I want to a new output using my result like this sample1@company.com---34 KZ 7898 sample2@company.com---34 KZ 7898 sample3@company.com---34 TZK 6785 sample2@company.com---34 TZK 6785

```
string input = "sample1@company.com;sample2@company.com----34 KZ 7898 sample3@company.com;sample2@company.com---- 34 TZK 6785";
var result = string.Join(" ", Regex.Split(input, "\\s(?=\\S+@)")
                             .Select(x=>{
                                var s = x.Split(new string[] {";","----"}, StringSplitOptions.RemoveEmptyEntries);
                                return string.Format("{0}---{2} {1}---{2}",s[0],s[1],s[2]);
                             }).ToArray());//
```
