Question

I have the following code:

string startAlpha = "A";
string StartSubAlpha = "a-e";
var currentPage = Directory.GetFiles(filePath, startAlpha + "*.pdf")
                           .Skip((pageNum - 1) * pageSize)
                           .Take(pageSize)
                           .Select(path => new FileInfo(path)).ToArray();

This works when only using startAlpha. But how can I integrate StartSubAlpha into it? I want to be able to find all files that has a starting letters (first 2) between "Aa-Ae" (from the example above).

Any suggestions?

There is a very similar question here.

The regex you’re looking for could be formulated as A[a-e].*
