Quickest Loop within a Loop

Currently I have a Loop with in a Loop to find if sometime in a List is contained within a string array:

foreach (var cl in compFileName)

{

foreach (var f in fileArray)

{

if (f.Contains(cl))

{

compToCopy.Add(f);

}

(sender as BackgroundWorker).ReportProgress(i, Convert.ToString(i));

i++;

I'm wondering if there is a more efficient way rather than doing a loop within a loop as even with just 30,000 in the list it takes some time to iterate through!

Accepted answer
Is it possible that more than one 'f' could contain a given 'cl' ?

If it isn't, then you could break from the inner loop after finding a match.

There shouldn't be more than one (though you never know!) ..but thats a good call about break the inner loop and should suffice. Thanks
