I want to use a CheckedListBox in an application where each item in the ListBox is the name of a folder on my hard drive and for the purpose of reading and writing text files to and from each of these folders I want to ensure that multiple item (a folder) can be selected at any time in the CheckedListBox

Thanks for reading :-)

private void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e)
            CheckedListBox.CheckedIndexCollection checkedIndices = checkedListBox1.CheckedIndices;
            if (checkedIndices.Count > 0)
                if (checkedIndices[0] != e.Index)
                    checkedListBox1.ItemCheck -= checkedListBox1_ItemCheck;
                    checkedListBox1.SetItemChecked(checkedIndices[0], true);
                    checkedListBox1.ItemCheck += checkedListBox1_ItemCheck;
                    // the user is unchecking the currently checked item, so deselect it...
                    checkedListBox1.SetSelected(e.Index, false);

I can select multiple files but my main question is How to select text files from the directory..

How can I achieve this via code in C#?

What did you try? Did you try the GetFiles method? Maybe Directory.GetFiles(yourfolder, "*.txt")?

Try this :-

On Selected event:-

string[] filePaths = Directory.GetFiles(@"FolderPath", "*.txt",

Loop through this filePaths array and get file names.
