DirectoryInfo.EnumerateFiles(filter)

A Repasky

I am using the statement

DirectoryInfo.EnumerateFiles(filter) where filter is a string. I want to set filter to be able to search for 2 different strings. How can I do that?

If I search for one string then:
filter = "CM_*";

But I want to search for 2 different strings.

Should I use:
filter = "CM_*, CDH_*";

I search online and cannot find the answer or if I can do this. Filter is a parameter coming in and it all has to be in one field. I thought I had figured it out but I cannot remember what I did.

Thanks,
arep

What I finally did was only use filter "C*". Then I used LINQ to determine if they were the filenames to keep.

Thanks. I thought there was a way to put them together. I had checked into this a couple of months ago and I cannot remember what I found out.

To the best of my knowledge, there's no way to combine two different filters into one. It certainly doesn't say you can do this in the documentation:

What I'd suggest you do is to split the incoming filter into two using the comma as separator. You then need to apply the two filters separately and (if necessary) amalgamate the resulting FileInfo arrays into a single array.
