Split calculator expression with binary and unary operations

Question

I get string input like: 1+2*5+sin100-2 and In order to calculate it I need to make array that will look like:

1,+,2,*,5,+,sin,100,-,2

Is there easy solution to do this problem? Currently I am doing it with loop on all the chars in the string but I want to know if c# offer easiest solution to this problem.

We cannot guess if there is any better solution then your current one as long as you do not provide the current one. However in any cases I guess this question should go to review-stack instead. — MakePeaceGreatAgain, Feb 09 '16 at 08:49
If you have already a working solution it's off-topic on SO anyway. — Tim Schmelter, Feb 09 '16 at 08:50
I'm voting to close this question as off-topic because questions about reviewing or improving existing, working code and lacking a specific question statement are off-topic for Stack Overflow. You may be able to get help on [Code Review](http://codereview.stackexchange.com/). — Tim Schmelter, Feb 09 '16 at 08:51
You can get most of the way with simple regex on split: `\b.\b` — freedomn-m, Feb 09 '16 at 08:52
@TimSchmelter is *questions about reviewing or improving existing, working code and lacking a specific question statement* in flagging options? Cause I can't find it! — Ghasem, Feb 09 '16 at 09:29
@AlexJolig Close - off topic - fourth option : Questions seeking debugging help ("why isn't this code working?") must include the desired behavior, a specific problem or error and the shortest code necessary to reproduce it in the question itself. Questions without a clear problem statement are not useful to other readers. See: How to create a Minimal, Complete, and Verifiable example. — freedomn-m, Feb 09 '16 at 11:40

I found easy solution.
You could just write it instead of complain that there is no code in the question.

string expression;//my calculator expression
string[] operators;//array that contains both unary and binary operators.
for(int i=0;i<operators.length;i++)
{
   expression = expression.replace(operators[i]," "+operators[i]+ " ");
}
string[] Values= expression.split(" ");
