You will likely need to make more than one call. But you can also encapsulate it in a method to hide those details.

You can make use of this search pattern: EC?92*. This will return all the files with names like EC92*, ECx92* where x could be anything.

Once you have this list, you can filter out using LINQ expression. Something like this:

C#

IEnumerable<string> fileList = Directory.GetFiles("D:\\Test", "EC?92*").Where(x => x.StartsWith("EC1") || x.StartsWith("EC2"));

What do you mean by not working? You can iterate IEnumerables using foreach.
