C# Check if items in checklistbox are un-checked?-CodePudding

I'm trying to list all items in a directory which has been successful. I need to check if the item's status is "Unchecked", and if it is to give me the name of it in a variable.

TL;DR: If item is unchecked, write item in variable.

private void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e)
        {
            if (checkedListBox1.GetItemChecked(e.Index) == true)
            {
                if (checkedListBox1.CheckedItems.Count != 0)
                {
                    // If so, loop through all checked items and print results.  
                    string s = "";
                    for (int x = 0; x < checkedListBox1.CheckedItems.Count; x  )
                    {
                        if (checkedListBox1.CheckedItems[x] == 0)
                        {
                            s = checkedListBox1.CheckedItems[x].ToString();
                        }
                    }
                    MessageBox.Show(s);
                }
            }
        }

This is my current code.

First thing, you don't need to check things against true or false.

You don't need to do it like you are doing,

checkedListBox1.GetItemChecked(e.Index) == true

Write it like this instead and it will work just fine,

if(checkedListBox1.GetItemChecked(e.Index))

And to get all un-checked items, the following should work. You need to check if checked list contains a checkbox. If it doesn't contain it, it will be an unchecked one. Code goes below.

string s = "";

for (int x = 0; x < checkedListBox1.CheckedItems.Count; x  )
{
    if (!checkedListBox1.CheckedItems.Contains(CheckedItems[x]))
    {
         s = checkedListBox1.CheckedItems[x].ToString();
    }
}
MessageBox.Show(s);

To get a list of all unchecked items:

private void button1_Click_1(object sender, EventArgs e)
{

    List<String> items = new List<String>();
    for (int i=0; i<checkedListBox1.Items.Count; i  )
    {
        if (!checkedListBox1.GetItemChecked(i))
        {
            items.Add(checkedListBox1.Items[i].ToString());
        }
    }

    // ... do something with "items" ...
    foreach(String item in items)
    {
        Console.WriteLine(item);
    }
}
