I want to cut the string from the example above using the split and trim functions. Can't we make it in one line?

Question

ex)12456,test      ,45,45,4563

I want to use c # to cut to the second digit of [,] in the example above and then remove the whitespace with the trim function.

-> 12456,test

Answer 1

You can do something like :

string sString = "12456,test      ,45,45,4563";
string sResult = sString.Substring(0, sString.IndexOf(',', sString.IndexOf(',') + 1)).TrimEnd();

Answer 2

or use LINQ and String.Join():

var result = String.Join(",", "12456,test      ,45,45,4563".Split(',').Select(i => i.Trim()).Take(2));
