Why doesn't it return what I need C#?

Question

C++ / C#

public static string Searcher(string path, string pattern)
        {
            
            var parts = new List<DirectoryInfo> { };
            
            DirectoryInfo dir = new DirectoryInfo(path);
            
            try
            {
                DirectoryInfo[] dirs = dir.GetDirectories();
                foreach (DirectoryInfo di in dirs)
                {
                    
                    parts.Add(di);
                }
            }
            catch { };
            foreach (DirectoryInfo part in parts.ToList())
            {
                
                if(part.ToString().Contains(pattern) == true)
                {

                    return part.ToString();

                }
                else
                {
                    
                    Searcher(part.ToString(), pattern);
                    
                }
                
                
            }
            return null;
        }

Why does the code return None and not part and how to fix it?

Answer 1

If I understand correctly, then the code should return a folder that contains some value (pattern) in the name. If so, then pattern should be looked for not in part.ToString(), but in part.Name.
