使用net use 命令實(shí)現(xiàn)遠(yuǎn)程機(jī)器的文件復(fù)制。
比如，從機(jī)器A操作實(shí)現(xiàn)把機(jī)器B的文件拷貝到機(jī)器A上，需要把機(jī)器B文件夾加上機(jī)器A的用戶權(quán)限。

這兩個(gè)方法是對(duì)機(jī)器B建立連接，連接成功后，用File.Copy就可以了
if (Ping("機(jī)器B"))
   {
    if (Connect("機(jī)器B","機(jī)器A用戶","機(jī)器A用戶訪問密碼"))
    {
     File.Copy("\\機(jī)器B\文件路徑\文件名稱","機(jī)器A存放文件完整路徑",true);
    }
   }
