Question

I have these two collections:

      List<string> files =
            Directory.GetFiles(FilePath).ToList().Select(file => new FileInfo(file).Name).ToList();

        string[] dirs = Directory.GetDirectories(FilePath);

However, I’d like to add both of these to an empty dictionary, so I have a large dictionary with paths and files. The thing I am not sure of, how/where do I specify the keys?

For files, I want the filename as the key, and for the directories, I want the last directory (e.g. c in a/b/c) to be the key. I know how to get this information with FileInfo/DirectoryInfo classes, but not sure how to include this in creating a dictionary from the above?

I’m using .NET V3.5 and LINQ is fine.

Thanks

For files, you can do

var  filesDictonary = Directory.GetFiles(FilePath)
                                      .Select(file => new FileInfo(file))
                                      .ToDictionary(f => f.Name, f => f);

for directories,

var directoriesDictonary = Directory.GetDirectories(FilePath)
                                     .Select(d  => new DirectoryInfo(d))
                                     .ToDictionary(d => d.Name, d => d);
