Traverse Folder, locate the folder

See 1:

public static string[] GetDirectories2(string dir, string regexPattern = null, int depth = 0, bool throwEx = false)
        {
            List<string> lst = new List<string>();

            try
            {
                foreach (string item in Directory.GetDirectories(dir))
                {
                    try
                    {
                        if (regexPattern != null && item.Contains(regexPattern))
                        { 
                            lst.Add(item); 
                        }

                        //递归
                        if (depth != 0) { lst.AddRange(GetDirectories2(item, regexPattern, depth - 1, throwEx)); }
                    }
                    catch { if (throwEx) { throw; } }
                }
            }
            catch { if (throwEx) { throw; } }

            return lst.ToArray();
        }

调用：DirUtil.GetDirectories2(rootDir, "Log_PayLogUnWrite", 6);

 

Referring to 2, this method is the first match is returned, there is a need to modify their own:

 

///  <the Summary> 
        /// Find specify the name of the folder, the default depth of 6
         ///  </ the Summary> 
        ///  <name = "path" param> path're looking for </ param> 
        ///  <param name = "searchDirName"> files to find a folder name </ param> 
        ///  <param name = "depth"> Find depth </ param> 
        ///  <returns a> </ returns a> 
        List < String > FindDirPath ( String path, String searchDirName, int depth = . 6 ) 
        { 
            List < String >lst = new List<string>();

            try
            {
                string[] dirs = Directory.GetDirectories(path);
                foreach (string dir in dirs)
                {
                    if (dir.Contains("$RECYCLE.BIN") || dir.Contains("System Volume Information"))
                        continue;

                    string dirName = dir.Substring(dir.LastIndexOf("\\") + 1);

                    if (dirName.ToLower().EndsWith("temp")) // This procedure needs to be skipped temp folder 
                        Continue ; 

                    IF (dirName == searchDirName) 
                    { 
                        lst.Add (the dir); 
                        BREAK ;   // first match is returned 
                    }
                     // recursive 
                    IF (depth =! 0 ) 
                    { 
                        lst.AddRange (FindDirPath (the dir, searchDirName)); 
                    } 
                    
                } 
            } 
            the catch (Exception EX) 
            { 
                UILog ( " FindDirPath1 EX: " + ex.Message);
            }

            return lst;
        }

调用 ：List<string> lst = FindDirPath("d:\\", Folder);
