Trim ComboBox items

I want to trim all ComboBox items for example:

ComboBox items

Processor:12000
Ram:5000


I want to trim string before colon (including 'colon') and send to listbox, so i can calculate all prices for items.
So plz tell me how can i do that.

Thanks

use this

Code:

---


String data = "Processor:12000";
String result = data.substring(data.lastIndexOf(":")+1);

---

we substring the String. String.substring([b[This is the Start Index[/b])
so data.lastIndexOf(":") -> return the index of last : found in the string..
and return ":12000" but we need only "12000" so +1 for the index

update:
sorry i dont see that you want to calculate. so

try this code instead

Code:

---

int total=0;
foreach (String text in [your list].Items) {
    total+= int32.Parse(text.Substring(text.LastIndexOf(":")+1));
}

ThankYou so much Neolitz, Your code works

I use this:

string substring;
comboBox1.Items.ToString();
foreach(string s in comboBox1.Items)
{

substring = s.Substring(s.LastIndexOf(":") + 1);
listBox1.Items.Add(substring);
}

so now my problem is when i hit ">" button for add only selected item, all items of combobox trim and tranfer to listbox.
this code works for all item button(>>) button but not for selected item(">")

please help me.

the foreach will work with >>
now for the > try to do this

instead of do it to all data in the combo box we will do to the item selected and insert it to the list

Code:

---

String temp = comboBox1.Text;
temp = temp.Substring(temp .LastIndexOf(":") + 1);
listBox1.Items.add(temp);

---

your mistake is you use "foreach" which means do to all data in combo box, when you only wanted 1 item to added when > pressed.

so for >> keep using the old one
and for > use the new one

Hope this helps

Yeeah!! ThankYou so much.
