can you tell me ?

Answer 1

You are welcome. Keep asking questions.

Answer 2

You can but the are a few things you should know about.
See in this code.
https://code.sololearn.com/cw0WMbX9Lx9Y/#cs

split returns an array of strings
string [] reversed_array;
reversed_array = reversed.Split('-');

split only allows one character reversed.Split('-'); instead of reversed.Split(' - '); (no space allowed, the are seen as characters.)

If you split string "a" you do not split string "reversed" so be carefull which string you are going to split

Does the textBox hold a string with a "-" in it.

please change you title to something more descriptive like "why i can not Split(' - ') on string reversed!", you a going to get a lot more answers if you question title is descriptive.

Hope this helps

Answer 3

Can you show me use with character Array .please !

Answer 4

It is a string array. An array of strings.

See how to use it, on the following pages.

I updated the code and put some more use of the string array in it.
