Solution 1

In the format you have chosen Id go for String.Split(" ") method, and then call convert to integer and store it in a new list of integers.

Link to String.Split() method[^].

Good answer, my 5!

Thanks :-) However I relized that he could use .StartsWith("0") also, but that would be more cumbersome.

Sergey Alexandrovich Kryukov 7-Apr-13 22:52pm

Actually, both solutions are cumbersome compared to a better one: TrimStart; please see my answer.

Solution 2

The easiest way is to call myStream.TrimStart('0'); please see:
http://msdn.microsoft.com/en-us/library/system.string.trimstart.aspx[^].

However, in's important to understand that you cannot remove anything from a string, as strings are immutable. All string methods "modifying" string actually don't modify any string object, they create a brand new string with appropriate content.

Well, I didnt know TrimStart, the rest is just politeness :-)

Sergey Alexandrovich Kryukov 8-Apr-13 0:33am

No, It's not about politeness. I mean, knowing each and every API is not the real knowledge which does not mean serious value. Understanding is of real value and is the real knowledge.

I actually agree with that, often I find that it is the struckturing of problem into an algorithem that is the hardest. Once that is done, its just a matter of searching or reading documentation.

Maciej Los 8-Apr-13 1:59am

Agree, me too.
+5!
