How can I create an array containing the checked items in a checkedlistbox using foreach loop (or any other way)?

I can't know the number of items in the list.

Answer 1

Assuming your using 3.5 or above..

object[] items = lb.CheckedItems.OfType<object>().ToArray();

And if you are adding a specific type of object to the CheckedListBox then you can replace object with the name of the class you use.

Can you help me in one more thing please? I used what you wrote: string[] fonts = fontBox.CheckedItems.OfType<string>().ToArray(); and than i wanted to write each string in the array on a new line in the rich text box(called fontBox), so i tried: for (int i = 0; i < fonts.Count(); i++) { fontBox.Text = fonts[i]; } and i also tried: foreach (string i in fonts) { fontBox.Text = i; } but none of them worked – Synod

for (int i = 0; i < fonts.Length; i++) – Nathalia

Thank you very much, it's working =], and i located another mistake, i told the program to write in the checkedlistbox, not in the rich text box. – Synod

Hi i am doing a similar kind of task . But instead of array i am using array list . I used the below code

ArrayList errorList = new ArrayList();
errorList = chklbErrorlist.CheckedItems.OfType<object>().ToList();

Cannot implicitly convert type System.Collections.Generic.List<object> to System.Collections.ArrayList

I added the items to the array and then added to the arraylist, It worked. How to add items directly to the araaylist instead of the array
