Spilit the data from List box

well....
Trim() the string!
Than create this:

String MyLine[] = listBox1.SelectedIndex.Text.Split(' ', StringSplitOptions.RemoveEmptyEntries);

string fileName = MyLine[MyLine.Length-1];
string time = MyLine[MyLine.Length-2];
string day = MyLine[MyLine.Length-3];
string monthname = MyLine[MyLine.Length-4];

I assume You string(" -rwxrwxrwx 1 owner group 3233 Jul 27 18:28 1.log ") will be always contains 9 items(ignoring the whitespaces),

Following might help you,

static void Main(string[] args)
{
    string data = "   -rwxrwxrwx 1 owner   group   3233 Jul 27 18:28 1.log";
    var result = data.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries).Skip(5);
    var date = string.Concat(result.FirstOrDefault(), result.Skip(1).FirstOrDefault());
    var time = result.Skip(2).FirstOrDefault();
    var fileName = result.Skip(3).FirstOrDefault();
}

You can do whatever you want with the strings stored in a list box, but you real mistake is that you're not working with the original data. You use some data to populate a list box, you do it in the form of strings; and then you try to extract the same data from the strings.

This is a completely wrong approach. There are two fixes.

First, you need to have some data layer. You use the data layer to populate UI and you use the data layers to do all other operations — with "real" original data, not string.

Second approach: you can and most usually should store actual "real" data in the list box, not string representation of it. The thing is: you can store instances of any type in the list view. The only problem is: what will be displayed in the list items? The answer is: whatever the method ToString returns. So, the solution is: create some data type, call it ListItemHelper. Put your original data in this type. Also, override object.ToString in this type to show your data the way you want. In this way, you always format data as string and never try to interpret this string as data.
