is there way this.thanks help.

to this, want randomize order in files being sorted.

using sort shown in answer (you can use more cryptographic approach if want)

var rnd = new system.random(); var files = directory.getfiles(pathtodirectory, "*.zip")                      .orderby(x => rnd.next())                      .take(numoffilesthatyouwant); 

you can evaluate files in foreach. should give number of files want process, in random order.
