how i split a string if it has two differnt symbol as "," &"-"

You can not access a function from usercontorl class unless you have instance of it in your page and the function is public. e.g. (usercontorl1.function1())

otherwise, you should have that function in a class inside AppCode

Sorry, for this mistake post
Anyway, no direct way to do this. However, there is two methods coming to my mind to this. first one be use "," and "-" as seperator which will split them to one array {java, 3, os, 2...}.
string[] array = input.Split(",-".ToCharArray());

The back draw of this method is the consistency if the input is inconsistence (e.g. java-3,os,internet-4,5-6-1,ospm-2).

Second method is the following

string[] array2 = input.Split(',');
List<string> set1 = new List<string>();
List<string> set2 = new List<string>();

for (int i = 0; i < array2.Length; i++)
{
string[] temp = array2[i].Split('-');
if (temp.Length == 2)
{
set1.Add(temp[0]);
set2.Add(temp[1]);
}
}
