C#实现一个局域网文件传输工具

工作需要，经常会在工作的台式机和笔记本之间传文件或者需要拷贝文本，两个机器都位于局域网内，传文件或者文本的方式有很多种，之前是通过共享文件夹来进行文件的拷贝，或者通过SVN进行同步。文本传递比较简单，可以通过两台机器上装QQ登两个号码，或者在共享目录下建一个TXT，或者发电子邮件等等。

不过上面这些方法总觉得不直接，所以想基于P2P做一个小的局域网文件和文字传输小工具。

WinForm的工程，界面方面的代码就不贴了，大家自己根据喜好设计就好了，主要把TCP数据传输的代码和逻辑贴出来：

1. 文件和文本传输的通用方法：

private string ReceiveControl(Socket socket)
{
int bufSize = 1024;
byte[] buf = new byte[bufSize];
int len = socket.Receive(buf);
return len > 0 ? Encoding.UTF8.GetString(buf, 0, len) : String.Empty;
}

private void SendControl(Socket socket, string controlMsg)
{
byte[] msgBytes = Encoding.UTF8.GetBytes(controlMsg);
socket.Send(msgBytes);
}

private string ReceiveContent(Socket socket, int contentLen)
{
int receivedLen = 0;
int bufSize = 1024;
byte[] buf = new byte[bufSize];
StringBuilder sb = new StringBuilder();
while (receivedLen < contentLen)
{
int len = socket.Receive(buf);
if (len > 0)
{
sb.Append(Encoding.UTF8.GetString(buf, 0, len));
receivedLen += len;
}
}
return sb.ToString();
}

private void SendContent(Socket socket, string content)
{
byte[] contentBytes = Encoding.UTF8.GetBytes(content);
SendControl(socket, contentBytes.Length.ToString());
ReceiveControl(socket);
socket.Send(contentBytes);
}

private void ReceiveFile(Socket socket, string fileName, int fileLen)
{
string filePath = Path.Combine(GetCurrentUserDesktopPath(), RenameConflictFileName(fileName));
using (Stream fs = new FileStream(filePath, FileMode.Create, FileAccess.ReadWrite))
{
int bufLen = 1024;
int receivedLen = 0;
byte[] buf = new byte[bufLen];
int len = 0;
while (receivedLen < fileLen)
{
len = socket.Receive(buf);
fs.Write(buf, 0, len);
receivedLen += len;
}
}
}

private void SendFile(Socket socket, string filePath)
{
using (Stream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read))
{
SendControl(socket, GetFileNameFromPath(filePath));
ReceiveControl(socket);
SendControl(socket, fs.Length.ToString());
ReceiveControl(socket);
int bufLen = 1024;
byte[] buf = new byte[bufLen];
long readLen = 0;
long fileLen = fs.Length;
int len = 0;
while (readLen < fileLen)
{
len = fs.Read(buf, 0, bufLen);
readLen += len;
int sentLen = 0;
int realSent = 0;
int left = 0;
while (sentLen < len)
{
left = len - realSent;
realSent = socket.Send(buf, sentLen, left, SocketFlags.None);
sentLen += realSent;
}
}
}
}

2.连接，发送文字/文件，重命名文件等方法：

private void SendText()
{if (connected){if (!String.IsNullOrEmpty(this.TextToSend.Text)){string txt = this.TextToSend.Text;SendControl(clientSocket, "Text");ReceiveControl(clientSocket);SendContent(clientSocket, txt);ReceiveControl(clientSocket);}}
}private void Connect()
{try{if (!connected){passive = false;IPAddress serverIPAddress = IPAddress.Parse(this.ServerIPAddress.Text);clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);clientSocket.Connect(serverIPAddress, 60000);string msg = ReceiveControl(clientSocket);if (msg.Equals("Connected")){this.ConnectBtn.Text = "Disconnect";connected = true;}}else{passive = true;SendControl(clientSocket, "Disconnect");clientSocket.Close();this.ConnectBtn.Text = "Connect";connected = false;}}catch (Exception err){MessageBox.Show(string.Format("Failed to connect to server, error: {0}", err.ToString()));}
}private void ServerThread()
{IPAddress local = IPAddress.Parse("0.0.0.0");Socket server = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);server.Bind(new IPEndPoint(local, 60000));server.Listen(1);while (true){Socket receivedClientSocket = server.Accept();IPEndPoint clientEndPoint = (IPEndPoint)receivedClientSocket.RemoteEndPoint;SendControl(receivedClientSocket, "Connected");if (passive){clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);clientSocket.Connect(clientEndPoint.Address, 60000);string msg = ReceiveControl(clientSocket);if (msg.Equals("Connected")){connected = true;this.ConnectBtn.Text = "Disconnect";this.ServerIPAddress.Text = clientEndPoint.Address.ToString();}}while (connected){string msg = ReceiveControl(receivedClientSocket);switch (msg){case "Disconnect":receivedClientSocket.Close();clientSocket.Close();this.ConnectBtn.Text = "Connect";passive = true;connected = false;break;case "Text":SendControl(receivedClientSocket, "Received");int length = Convert.ToInt32(ReceiveControl(receivedClientSocket));SendControl(receivedClientSocket, "Received");string content = ReceiveContent(receivedClientSocket, length);SendControl(receivedClientSocket, "Received");this.TextToSend.Text = content;break;case "File":SendControl(receivedClientSocket, "Received");string fileName = ReceiveControl(receivedClientSocket);SendControl(receivedClientSocket, "Received");int fileLen = Convert.ToInt32(ReceiveControl(receivedClientSocket));SendControl(receivedClientSocket, "Received");ReceiveFile(receivedClientSocket, fileName, fileLen);SendControl(receivedClientSocket, "Received");MessageBox.Show("File Received");break;}}}
}private string GetFileNameFromPath(string path)
{int index = path.LastIndexOf('\\');return path.Substring(index + 1);
}private string RenameConflictFileName(string originalName)
{string desktopPath = GetCurrentUserDesktopPath();int extensionIndex = originalName.LastIndexOf(".");string fileName = originalName.Substring(0, extensionIndex);string extensionName = originalName.Substring(extensionIndex + 1);int renameIndex = 1;string newNameSuffix = String.Format("({0})", renameIndex);string finalName = originalName;string filePath = Path.Combine(desktopPath, finalName);if (File.Exists(filePath)){finalName = String.Format("{0} {1}.{2}", fileName, newNameSuffix, extensionName);filePath = Path.Combine(desktopPath, finalName);}while (File.Exists(filePath)){renameIndex += 1;string oldNameSuffix = newNameSuffix;newNameSuffix = String.Format("({0})", renameIndex);finalName = finalName.Replace(oldNameSuffix, newNameSuffix);filePath = Path.Combine(desktopPath, finalName);}return finalName;
}private string GetCurrentUserDesktopPath()
{return Environment.GetFolderPath(System.Environment.SpecialFolder.Desktop);
}
