ftpc源码

❶ 求一个完美无错C#的ftp源码，最好是中文

自己把这些方法写到一个类里.我分二次回答,一次...您的回答内容多于10000字，请删减！ string ftpServerIP;
string ftpUserID;
string ftpPassword;

FtpWebRequest reqFTP;

private void Connect(String path)//连接ftp
{
// 根据uri创建FtpWebRequest对象
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(path));
// 指定数据传输类型
reqFTP.UseBinary = true;
// ftp用户名和密码
reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
}

public FtpUpDown(string ftpServerIP, string ftpUserID, string ftpPassword)
{
this.ftpServerIP = ftpServerIP;
this.ftpUserID = ftpUserID;
this.ftpPassword = ftpPassword;
}

//都调用这个
//从ftp服务器上获得文件列表
private string[] GetFileList(string path, string WRMethods)
{
string[] downloadFiles;
StringBuilder result = new StringBuilder();
try
{
Connect(path);
reqFTP.Method = WRMethods;

WebResponse response = reqFTP.GetResponse();
StreamReader reader =
new StreamReader(response.GetResponseStream(), System.Text.Encoding.Default);//中文文件名
string line = reader.ReadLine();

while (line != null)
{
result.Append(line);
result.Append("\n");
line = reader.ReadLine();
}

// to remove the trailing '\n'
result.Remove(result.ToString().LastIndexOf('\n'), 1);
reader.Close();
response.Close();

return result.ToString().Split('\n');
}
catch (Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.Message);
downloadFiles = null;

return downloadFiles;
}
}

//从ftp服务器上获得文件列表
public string[] GetFileList(string path)
{
return GetFileList("ftp://" + ftpServerIP + "/" + path,
WebRequestMethods.Ftp.ListDirectory);
}

//从ftp服务器上获得文件列表
public string[] GetFileList()
{
return GetFileList("ftp://" + ftpServerIP + "/",
WebRequestMethods.Ftp.ListDirectory);
}

//从ftp服务器上载文件的功能
public void Upload(string filename)
{
FileInfo fileInf = new FileInfo(filename);
string uri = "ftp://" + ftpServerIP + "/" + fileInf.Name;

Connect(uri);//连接
// 默认为true，连接不会被关闭
// 在一个命令之后被执行
reqFTP.KeepAlive = false;
// 指定执行什么命令
reqFTP.Method = WebRequestMethods.Ftp.UploadFile;
// 上传文件时通知服务器文件的大小
reqFTP.ContentLength = fileInf.Length;
// 缓冲大小设置为kb
int buffLength = 2048;
byte[] buff = new byte[buffLength];

int contentLen;
// 打开一个文件流(System.IO.FileStream) 去读上传的文件
FileStream fs = fileInf.OpenRead();

try
{
// 把上传的文件写入流
Stream strm = reqFTP.GetRequestStream();
// 每次读文件流的kb
contentLen = fs.Read(buff, 0, buffLength);

// 流内容没有结束
while (contentLen != 0)
{
// 把内容从file stream 写入upload stream
strm.Write(buff, 0, contentLen);
contentLen = fs.Read(buff, 0, buffLength);
}

// 关闭两个流
strm.Close();
fs.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Upload Error");
}
}

❷ 求C#写的FTP文件多线程源码，服务器客户端都有就好了。发送到邮箱也行[email protected]

FTP服务器源码？难道你自己想实现一个自定义的建议FTP服务吗？这样不是不行，关键是ftp服务本来就是一种古老的文件共享协议，建立在TCP/IP协议上，这已经是实现了的东西，有自己的通信协议，为什么还要自己写一个服务？

要FTP客户端,负责和服务器通信的话，倒是有。

❸ 求FTP CLIENT源码（java）

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.StringTokenizer;
import sun.net.TelnetInputStream;
import sun.net.ftp.FtpClient;

public class FtpClientDemo {
public static int BUFFER_SIZE = 10240;
private FtpClient m_client;
// set the values for your server
private String host = "";
private String user = "";
private String password = "";
private String sDir = "";
private String m_sLocalFile = "";
private String m_sHostFile = "";
public FtpClientDemo() {
try {
System.out.println("Connecting to host " + host);
m_client = new FtpClient(host);
m_client.login(user, password);
System.out.println("User " + user + " login OK");
System.out.println(m_client.welcomeMsg);
m_client.cd(sDir);
System.out.println("Directory: " + sDir);
m_client.binary();
System.out.println("Success.");
} catch (Exception ex) {
System.out.println("Error: " + ex.toString());
}
}
protected void disconnect() {
if (m_client != null) {
try {
m_client.closeServer();
} catch (IOException ex) {
}
m_client = null;
}
}
public static int getFileSize(FtpClient client, String fileName)
throws IOException {
TelnetInputStream lst = client.list();
String str = "";
fileName = fileName.toLowerCase();
while (true) {
int c = lst.read();
char ch = (char) c;
if (c < 0 || ch == '\n') {
str = str.toLowerCase();
if (str.indexOf(fileName) >= 0) {
StringTokenizer tk = new StringTokenizer(str);
int index = 0;
while (tk.hasMoreTokens()) {
String token = tk.nextToken();
if (index == 4)
try {
return Integer.parseInt(token);
} catch (NumberFormatException ex) {
return -1;
}
index++;
}
}
str = "";
}
if (c <= 0)
break;
str += ch;
}
return -1;
}
protected void getFile() {
if (m_sLocalFile.length() == 0) {
m_sLocalFile = m_sHostFile;
}
byte[] buffer = new byte[BUFFER_SIZE];
try {
int size = getFileSize(m_client, m_sHostFile);
if (size > 0) {
System.out.println("File " + m_sHostFile + ": " + size
+ " bytes");
System.out.println(size);
} else
System.out.println("File " + m_sHostFile + ": size unknown");
FileOutputStream out = new FileOutputStream(m_sLocalFile);
InputStream in = m_client.get(m_sHostFile);
int counter = 0;
while (true) {
int bytes = in.read(buffer);
if (bytes < 0)
break;
out.write(buffer, 0, bytes);
counter += bytes;
}
out.close();
in.close();
} catch (Exception ex) {
System.out.println("Error: " + ex.toString());
}
}
protected void putFile() {
if (m_sLocalFile.length() == 0) {
System.out.println("Please enter file name");
}
byte[] buffer = new byte[BUFFER_SIZE];
try {
File f = new File(m_sLocalFile);
int size = (int) f.length();
System.out.println("File " + m_sLocalFile + ": " + size + " bytes");
System.out.println(size);
FileInputStream in = new FileInputStream(m_sLocalFile);
OutputStream out = m_client.put(m_sHostFile);
int counter = 0;
while (true) {
int bytes = in.read(buffer);
if (bytes < 0)
break;
out.write(buffer, 0, bytes);
counter += bytes;
System.out.println(counter);
}
out.close();
in.close();
} catch (Exception ex) {
System.out.println("Error: " + ex.toString());
}
}
public static void main(String argv[]) {
new FtpClientDemo();
}
}

❹ 怎么通过ftp获取网站源码

先安装FTP软件，推荐flashfxp或cuteftp
然后你需要FTP的IP、端口、FTP账户、FTP密码
再通过FTP软件链接到服务器，然后就可以下载网站源码了

❺ 求易语言绕过cfTP安全的源码

用vmp保护模块

VMP保护开始（）

欲保护的程序

VMP保护结束（）

这个是模块 送上
