another way than iterare 5 times

denny simon

I have a string string1="11001";
I want to Check a checkListBox in each index step according to the "1" value of
the string1
to do that I shift the string1 five times to the right and compare
the excess value with "1" ,and if the value equals then I check
the ChecklistBox index accordingly
But I think this way is not fast because i have to iterate five times
is there a better way than this ?
Please give me the idea

thx
denny

Here is the another way .

if my answer help you than please check "Do you like this answer" check box :)

            string string1 = "1101";

            IEnumerator enum1 = string1.GetEnumerator();

            int i=0;

            while (enum1.MoveNext())

            {

checkedListBox1.SetItemCheckState(i++, (CheckState)int.Parse(enum1.Current.ToString()));

            }

Yes, theLizard, that is better.

More straight forward.

            string s = "110101";

            for(int i = 0; i < checkedListBox1.Items.Count; i++)
               checkedListBox1.SetItemCheckState(i, s[i] == '1' ? CheckState.Checked : CheckState.Unchecked);

A simpler way...

The first way is not always the best way.

Use of string1[i] would be easier, as in:
for (int i=0; i checkedListBox1.SetItemCheckState(i, (CheckState)int.Parse(string1[i].ToString()));
Since you need a number for the CheckedListBox item index, use of the IEnumerator is unnecessary.

You can use string1[i] to access the character at index i.
