如果你的意思是socket互传的话，看看这个，否则就当我没说吧
---------------------------------------------------------
（一）用nmstrm,nmstrmserv
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
StdCtrls, Psock, NMSTRM;
type
TForm1 = class(TForm)
NMStrm1: TNMStrm;
NMStrmServ1: TNMStrmServ;
Button1: TButton;
procedure Button1Click(Sender: TObject);
procedure NMStrmServ1MSG(Sender: TComponent;
const sFrom: String;
strm: TStream);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.DFM}
procedure TForm1.Button1Click(Sender: TObject);
var
MyStream: TMemoryStream;
begin
MyStream:= TMemoryStream.Create;
try
NMStrm1.Host:='127.0.0.1';
MyStream.LoadFromFile('c:/test.exe');
NMStrm1.FromName:='c:/test1.exe';
//发送一个文件名
NMStrm1.PostIt(MyStream);
finally
MyStream.Free;
end;
end;
procedure TForm1.NMStrmServ1MSG(Sender: TComponent;
const sFrom: String;
strm: TStream);
var
MyStream: TMemoryStream;
begin
MyStream := TMemoryStream.Create;
MyStream.LoadFromStream(strm);
MyStream.SaveToFile(sFrom);
end;
end.
而且Delphi有自带的一个例子，在Delphi/demo/fastnet/strm目录里就是实现的文件传输。
-----------------------------------------------------------------------
（二）用nmftp
给个通俗的：（ftp客户方用fastnet下的nmftp控件）
nmftp1.Host:=xxx.xxx.xxx.xxx;
nmftp1.port:=21;
nmftp1.Connect;
nmftp1.userid:=xxx;
nmftp1.password:=xxx;
nmftp1.reportlevel:=1;
nmftp1.timeout:=xxxx;
nmftp1.Download(ftp服务器上的文件,存为本地哪个文件);
(下载)
nmftp1.Abort;（暂停下载）
nmftp1.Downloadrestore(ftp服务器上的文件,存为本地哪个文件);（下载的断点续传）
nmftp1.upload(xxxxx,xxxxx);
(上传)
nmftp1.upload(xxx.xxxx);
(上传的断点续传)
如果你想自己做一个ftp服务器,delphi没有自带的控件
可以用ics控件组上的ftpserver控件
