For loop is exited before completion

Question

[code]for (int d = 0; d { if (checkedListBox1.GetItemChecked(d) == true) { checkedListBox1.Items.RemoveAt(d); } }[/code] The for loop is completed before it's suppose to end... Why is this? I checked all the items (~20) in the checkedListBox but when I run this code not all the items are removed; some are left over. Why is this? I even tried removing if(checkedListBox1.GetItemChecked).

An explanation of what was happening checkedlistbox1 contains 10 items numbers 1 - 10 you check item 12 & 3 and with marks code you first remove item 1 Item 2 is now becomes item 1 The code loops to remove item 2 which is now item 3 so item 2 remains With the code I supplied we first remove item 3 so that item 1 & 2 are still in their original positions Then we remove 2 lastly 1 Hope this helps you

You can use the debugger to single-step through the code to learn what happens. Assuming that Frogleg's suggestion works an alernative would be to use foreach instead of for. If Frogleg's suggestion does not work then try using foreach.

Try this for (int d = checkedListBox1.Items.Count - 1; d >= 0; d--) { if (checkedListBox1.GetItemChecked(d)) { checkedListBox1.Items.RemoveAt(d); } }
