The following is a description by the author of the translation. Introduction At this time, I wrote a C # component for the first time. I decided to create a component to implement FTP. Here is a simple code to use this component. I cannot guarantee that the code of this component can work well under any circumstances, but I think I will improve it in the feedback I get. Add this component to Toolbox (using custom Toolbox) and put it in your form. This project includes a simple FTP client. Code:
Connect to the FTP server:
Ftpc. Username = efusername. text;
Ftpc. Password = efpassword. text; Ftpc. hostname = cbftpserver. text;
Ftpc. Connect (); Login Server:
Private void ftpc_connected (Object sender, ftpcom. ftpeventargs E)
{
Ftpc. login ();
} After successful connection, the time will be recorded:
Private void ftpc_logged (Object sender, ftpcom. ftpeventargs E)
{
Ftpc. dir ();
} Get a directory list:
Private void ftpc_dircompleted (Object sender, ftpcom. ftpeventargs E)
{
Int I = 0;
Int idimage = 0;
String MSG; MSG = "transfered" + E. totalbytes. tostring () + "bytes in" +
(Float) E. timeelapsed/1000). tostring () + "seconds" + CRLF;
Textlog. selectioncolor = color. Black;
Textlog. appendtext (MSG ); Serverview. beginupdate ();
Serverview. Items. Clear ();
Imglistserversmall. Images. Clear (); Listviewitem lvitem = new listviewitem ("..");
Serverview. Items. Add (lvitem ); For (I = 0; I <ftpc. filecount; I ++)
{
If (ftpc. isfolder (I ))
{
String [] items = new string [2];
Items [0] = ftpc. getfilename (I );
Items [1] = ftpc. getfilesize (I). tostring ();
Imglistserversmall. Images. Add (m_iconfolder );
Serverview. Items. Add (New listviewitem (items, idimage ++ ));
}
}
For (I = 0; I <ftpc. filecount; I ++)
{
If (! Ftpc. isfolder (I ))
{
String [] items = new string [2];
Items [0] = ftpc. getfilename (I );
Items [1] = ftpc. getfilesize (I). tostring ();
Imglistserversmall. Images. Add (extracticon. getIcon (items [0], false ));
Serverview. Items. Add (New listviewitem (items, idimage ++ ));
}
}
Serverview. endupdate ();
This. cursor = cursors. default;
} Download an object:
Private void serverview_mousemove (Object sender,
System. Windows. Forms. mouseeventargs E)
{
If (E. Button! = 0)
{
String MSG = ""; For (INT I = 0; I <serverview. selecteditems. Count; I ++)
{
MSG + = serverview. selecteditems [I]. Text + "/N ";
} Serverview. dodragdrop (MSG, dragdropeffects. Copy | dragdropeffects. Move );
}
} Private void localview_dragenter (Object sender, system. Windows. Forms. drageventargs E)
{
If (E. Data. getdatapresent (dataformats. Text ))
E. effect = dragdropeffects. copy;
Else
E. effect = dragdropeffects. None;
} Private void localview_dragdrop (Object sender, system. Windows. Forms. drageventargs E)
{
String MSG = E. Data. getdata (dataformats. Text). tostring (); String [] filename = MSG. Split (New char [] {'/N '});
Foreach (string sfile in Filename)
{
Ftpc. filedownload (sfile );
}
} When the download ends, a filedownloadcompleted event will be returned:
Private void ftpc_filedownloadcompleted (Object sender, ftpcom. ftpeventargs E)
{
String MSG = "transfered" + E. totalbytes. tostring () + "bytes in" +
(Float) E. timeelapsed/1000). tostring () + "seconds" + CRLF;
Textlog. selectioncolor = color. Black;
Textlog. appendtext (MSG );
Filllocalview (m_currentfolder );
} Delete an object:
For (INT I = 0; I <serverview. selecteditems. Count; I ++)
{
Ftpc. Delete (serverview. selecteditems [I]. Text );
}
Ftpc. dir (); Rename a file:
Private void serverview_afterlabeledit (Object sender,
System. Windows. Forms. labelediteventargs E)
{
If (E. Label! = NULL)
{
This. cursor = cursors. waitcursor; String newfilename = E. label;
If (m_previusfilename = "new folder ")
{
Ftpc. dircreate (newfilename );
}
Else
{
Ftpc. Rename (m_previusfilename, newfilename );
}
Ftpc. dir ();
}
} Disconnect:
Ftpc. Disconnect ();
Serverview. Items. Clear (); Hope to help you.
