 Public stringreadimagespaths () {stringresult =string.            Empty; Try             {                stringPath =System.IO.Directory.GetCurrentDirectory (); DirectoryInfo Files=NewDirectoryInfo (path+@"\images"); Fileinfo[] FileInfo=files.                GetFiles (); foreach(FileInfo fileinchFileInfo) {                    //result + files [email protected] "\" + file. Name + ";";Result + = file. Name +";"; }            }            Catch(Exception ex) {_log.            Error (ex); }            returnresult; }

Download the picture according to the file name and save as:

 PublicStream Downloadimage (stringname) {            stringPath =System.IO.Directory.GetCurrentDirectory (); DirectoryInfo Files=NewDirectoryInfo (path +@"\images"); Fileinfo[] FileInfo=files.            GetFiles ();            FileStream filecontent; Byte[] Filebyte=Newbyte[1]; foreach(FileInfo fileinchFileInfo) {                if(file. Name = =name) {                    stringfilepath = files +@"\"+name; Filecontent=NewFileStream (Filepath,filemode.open); Filebyte=Newbyte[filecontent.                    Length]; Filecontent. Read (Filebyte,0, Filebyte.                    Length); Filecontent.                Close (); }            }            stringEncodedfilename =Httputility.urlencode (name); WebOperationContext.Current.OutgoingResponse.ContentType="Application/octet-stream"; WEBOPERATIONCONTEXT.CURRENT.OUTGOINGRESPONSE.HEADERS.ADD ("content-disposition",string. Format ("attachment;filename=\ "{0}\"; Filename*=utf-8 ' {1}", Encodedfilename, Encodedfilename)); return NewMemoryStream (Filebyte);
