Question

I have an string like this:

string s1 = "abc,tom,--Abc, tyu,--ghh";

This string is dynamic, and I need to remove all substrings starting with "--".
Output for the example string:

s1 = "abc,tom, tyu";

How can I remove these substrings?

Answer 1

Look at String.Replace

I am sorry, I should have read the question correctly.
Regex comes to mind, for your case.

EDIT

LINQ

string s1 = "abc,tom,--Abc, tyu,--ghh";
var s2 = s1
  .Split(',')
  .Where(s => s.StartsWith("--") == false)
  .Aggregate((start, next) => start + "," + next);
Console.WriteLine(s2);
