C# checkedListBox and EventArgs

Answer 1

Your description is a little messy...however, from what I gathered from it, you have a checklistbox on a form and you want to update it whenever an event is triggered (via your delegate method)

Something like this would work:

public void AddToList(List<DirectoryInfo> di, string mypath)                 
{                
    mypath = null // if you need to set this to null do it outside the loop so it is only done once
    try
    {
        foreach (DirectoryInfo info in di)
        {
            DirInfoCheckedListItem cb = new DirInfoCheckedListItem(info);
            checkedListBox4.Items.Add(cb);
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show(w.Message);
    }
}

public class DirInfoCheckedListItem
{
    private DirectoryInfo info;
    public DirInfoCheckListBoxItem(DirectoryInfo info)
    {
        this.info = info;
    }

    public string Text { get { return this.info.Name; } }
    public object Tag { get { return this.info; } }
    public override string ToString()
    {
        return this.Text;
    }
}
