I'm having trouble trimming all the whitespaces(tab, etc.) for a given string. I've tried a number of recommended solutions, but have yet have any sort of luck.
for example
["7 ", " +", "1", "/" "0""]
needs to return
["7","+","1","/","0"]
Another aspect to consider is that
string[] substrings = Regex.Split(exp, "(\\()|(\\))|(-)|(\\+)|(\\*)|(/)");
must also be used, and I'm working on a passed in string.
You coud use Linq:
var a = new string[]{"7 ", " +", "1", "/", null, "0"};
var b = a.Select(x => x == null? null: x.Trim()).ToArray();
or do it in-place applying Trim to every element.
Another aspect to consider is that ...
This was not in the first edition of the question, and Regex is not considered in the answer.
.Where(x => !string.IsNullOrEmpty(x)).Select(x => ...
"".Trim is not a problem, but nulls could be. I updated the answer.
null in a?You can use Linq too.
string text = "My text with white spaces...";
text = new string(text.ToList().Where(c => c != ' ').ToArray());
