Sorting the results of DirectoryInfo.GetFiles

Say you wanted toget a list of all the SLN (Visual Studio Solution) files in a given directory and all child directories, sorted alphabetically, you could use something similar to this:

        public static void GetSolutionList()
        {
            DirectoryInfo d = new DirectoryInfo(@"C:\Solutions\");
            FileInfo[] items = d.GetFiles("*.sln", SearchOption.AllDirectories);

            Array.Sort(items, new FileInfoComparer());
            List<string> solutions = new List<string>();

            foreach (FileInfo f in items)
            {
                solutions.Add(f.FullName);
            }
        }
        public class FileInfoComparer : IComparer<FileInfo>
        {
            public int Compare(FileInfo x, FileInfo y)
            {
                return ((new CaseInsensitiveComparer()).Compare(y.Name, x.Name));
            }
        }

The key bit of "magic" is the FileInfoComparer - whilst this is a simple one, it shows how easy it is to implement a comparer for the purposes of sorting!
