Select files from IEnumerable<>

Question

Hi there, I have the following:

var selectedFilesToReplace = new List<string>();
foreach (string file in files) 
{
    selectedFilesToReplace.AddRange(listUploadedFiles
        .Where(x => Path.GetFileNameWithoutExtension(x) == file));
}

that fill the selectedFilesToReplace collection with a set of FULL path files. I need to select only the file name with its extension.

Is this possible in a single Linq expression?

Answer 1

var fileNameOnly = selectedFilesToReplace.Select(Path.GetFileName);

Answer 2

Like this:

selectedFilesToReplace.AddRange(listUploadedFiles
    .Where(x => Path.GetFileNameWithoutExtension(x) == file))
    .Select(p => Path.GetFileName(p));

In C# 4, you can also write

selectedFilesToReplace.AddRange(listUploadedFiles
    .Where(x => Path.GetFileNameWithoutExtension(x) == file))
    .Select(Path.GetFileName);
