1.配置ftp 服务器 (xp下局域网内)

1.server下，打开设置-->控制面板-->管理工具-->IIS,找到本地计算机下的ftp站点，打开默认ftp站点的属性，做如下配置：
1）ftp站点选项卡
IP地址：指定一IP地址，如：192.168.0.101
端口号：21
2）主目录选项卡
选择内容来源为：此计算机上的目录
ftp站点目录：配置一本机目录，最好为非系统盘，如D:\ftp。选择读取、写入、记录访问

2.server下，网络邻居里的本地连接，属性-->常规-->TCP/IP协议-->属性，取消自动获取IP地址，手动输入如上IP：192.168.0.101

3.client下，网络邻居里的本地连接，属性-->常规-->TCP/IP协议-->属性，取消自动获取IP地址，手动输入IP：192.168.0.102

4:测试：把文件copy到ftp主目录下，即D:\ftp，通过在server端以及client端的IE，输入ftp://192.168.0.101或者ftp://servername (作为服务器的计算机名，可在我的电脑-->属性-->计算机名里获得)可访问到文件，则测试成功。

2.在C#项目下添加ftp类
