Question

Hello I am new here , I have to make token set program in C# , I have to break words in C# , I used split method , but it split words in space , I used it with delimeters , it splits words on my given delimeters and also does not write them ,

void main()
{
}

, I want following o/p
void
main
(// break word here and write character also
)
{
}

How can I do this ?
