ftp客户端程序
最近做一个ftp客户端程序，有用到这些代码。与现在ftp客户端最大不同是，可以根据更新时间以及文件后缀名来过滤文件这对一个项目经理来说无疑可以节省很多时间、精力。
public partial class mainForm : Form

string path; //目录名 也可以用相当路径
string filter = "*.*"; //文件类型
int m_numFiles = 0; //文件总数
ArrayList m_pathList = new ArrayList();//包含所有文件路径的数组
string[] files; //所有文件名
DateTime time;
string m_strWinSCPPath;
