use IdAllFTPListParsers

IdFTP1.List(LS);

中文目录乱码

2个步骤解决

use IdGlobal

idftp2.List(v_filelist,'',False); //这样写防止中文乱码。第三个参数必须为False

//IdFtp2.IOHandler.DefStringEncoding := TEncoding.ANSI;

IdFTP1.IOHandler.DefStringEncoding := IndyTextEncoding_OSDefault;// tencoding.Default;

The system cannot find the file specified.

编码转换方法没试这样写行不行

IndyTextEncoding(TEncoding::ANSI);
