How to get all items to a string [] from listview?

ProcessStartInfo startInfo = new ProcessStartInfo();

startInfo.CreateNoWindow = true;
startInfo.UseShellExecute = false;
startInfo.FileName = @".\ext.exe";
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
int i=0;
string item = listView1.Items[i++].Text;
startInfo.Arguments = "--logfile=duration_output.txt " + (item);

I am trying to list all items as a string[], but then the application gives me an empty logfile.
When I use the simple string item = listView1.Items[i++].Text, it gives me only one the first file on the output.

How is it possible to do that?

//here is something you can use getting directly at System.Diagnostics // it works just replace Console.WriteLine with what ever Stream Class you are using. //Replace where I use System.Diagnostics with ListView Iterate thru the listview itesm

    System.Diagnostics.Process[] proc = System.Diagnostics.Process.GetProcesses();
    foreach(Process theprocess in proc)
    {
      Console.WriteLine("Process: {0} ID: {1}", theprocess.ProcessName, theprocess.Id);
    }

Are you looking for something like this?

startInfo.Arguments = "--logfile=duration_output.txt " +
    string.Join(" ", from item in listView1.Items.Cast<ListViewItem>()
                     select @"""" + item.Text + @""""
               );

You need to iterate over all the items in the listview and concatenate them into a single string:

string item = string.Empty;
foreach (ListViewItem anItem in listView1.Items)
{
  item += " " & anItem.Text;
}

Try this:

string[] items = listView1.Items.Select(x => x.Text).ToArray();

StringBuilder args = new StringBuilder();
args.Append("--logfile=duration_output.txt");
foreach( var str in listView1.Items )
{
    args.Append( " " );
    args.Append( str );
}
