C # FTP Determines whether a directory exists and creates folders

Work in the project has been using the FTP upload log file problems, the new server is set up, the log can not be uploaded. Just to learn about FTP.

The process in the program is, a timer, every minute to detect the configuration file in the local log file path has no log files, if any, upload to the server, and then delete the local files. The logs are in a date, a folder per day, followed by a log type, grouped by type. Detects if the folder exists on the server before uploading and creates a file if it does not exist.

Here is the code. (FTP-only part)

/// <summary>        ///determine if a file's directory is stored, not saved, or created/// </summary>        /// <param name= "Destfilepath" >Local Files directory</param>         Public voidCheckDirectoryAndMakeMyWilson3 (stringDestfilepath) {            stringFulldir = Destfilepath.indexof (':') >0?

Length; i++)// loop through each folder {if(Dirs[i] = ="")Continue; stringDIR =Dirs[i]; //if it is a/start path, the first one is empty                if(dir! =NULL&& dir.
