Question

I have this arraylist:

ArrayList ftd = new ArrayList();
ftd.Add(new string[]{ "foo1.txt", "01.01.2011" });
ftd.Add(new string[]{ "foo2.txt", "04.01.2011" });
ftd.Add(new string[]{ "foo3.txt", "09.01.2011" });

and after some logic the arraylist looks something like this:

[0] = { "foo1.txt", "01.01.2011" }
[1] = { "", "04.01.2011" }
[2] = { "foo3.txt", "09.01.2011" }

NOW: how do i loop thru ftd and remove elements there the elements first var is “”?

Answer 1

Try using this:

var result = ftd.Cast<string[]>().Where(x => x[0] != "");
