C#使用ftp 下载文件并删除ftp中的数据

野鼻孔 2016-08-16 05:39:52

大神帮忙看看代码，我想从ftp上下载数据到本地，然后直接删除tfp已下载的数据。
但是用cmd的方式需要一步步来，且有个时效性，只能先copy然后再删除，copy开始和最后删除有个时间差，所以只能用程序来解决。
我这边的源文件路径为ftp://ip/test1，我这边直接把serverip,username,password,url输入不知道可以不可以。
且我想用cmd中的prompt交互模式，然后最后使用全部copy mget *.txt
这边目标文件路径不知道怎么设置。就直接在本地C:\test1

求大神帮助，非常感谢
