调用 1.初始化连接 CommonData.FtpServer_MappingFile new FTPHelper(ftpIPAddress, ftpUser, ftpPw); 2.下载 //url 服务器下载地址 //savefilePath 保存文件目录 //fileName 文件名只是文件名 CommonData.FtpServer_MappingFile.DownloadByUrl(url, savefilePath, fileName, true); 3.上传 //currentDirectory 本地文件完整路径包括文件名 //ftpUploadFileName FTP服务器完整上传路径包括文件名 CommonData.FtpServer_MappingFile.Upload(currentDirectory, ftpUploadFileName);
