split not working correctly

I am trying to save the groups in a string to an array so that I can use them in individual variables if I need to. For this I use split but for some reason I only get the full string in the first position in the array: ultimate_array[0]. If I want to use ultimate_array[1] I get an exception like "out of bounds". Do you have any idea what am I doing wrong?

String string_final = "";
String[] ultimate_array = new String[100];
String sNrFact = "";

string_final="Nrfact#$idfact1#$valfact1#$idfact2#$valfact2#$idfact3#$valfact3#$idfact4#$valfact4#$idfact5#$valfact5#$idfact6#$valfact6#$idfact7#$valfact7#$idfact8#$valfact8#$idfact9#$valfact9#$idfact10#$valfact10";

ultimate_array = string_final.split("#$");
sNrFact = ultimate_array[0];

Just replace your line:

ultimate_array = string_final.split("#$");

with:

ultimate_array = string_final.Split(new string[] { "#$" }, StringSplitOptions.None);

I hope your problem is resolved...

ultimate_array = string_final.split("#\\$");

The reason your split is not working correctly is that split uses regex and "$" is a special character for regexes(drekka)

You need to escape $ (end of string)

ultimate_array = string_final.split("#\\$");

The split takes an regular expression and $ is a special character (end of string) so you have to escape it with backslash \. Anyway it is also special character, this time in Java, so you have to escape it also. The final code is:

ultimate_array = string_final.split("#\\$");
