C#socks5 proxy (socks5 proxy udp)

C#socks5 Agent

In C# programming, the use of socks5 proxy can help us to realize more secure and reliable network communication.Socks5 proxy is a network transport protocol, it can realize the proxy forwarding of UDP and TCP data, which provides a more flexible way for network communication. Let's see how to implement socks5 proxy in C#.

"`csharp
using System.
Net; using System.
using System.Net.

class Socks5Proxy
{
static void Main()
{
// Set the proxy server address and port
string proxyServer = "127.0.0.1";
int proxyPort = 1080;

// Create a socket connection to the proxy server
Socket proxySocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
proxySocket.Connect(proxyServer, proxyPort);

// Send a socks5 proxy request
byte[] request = { 0x05, 0x01, 0x00 };
proxySocket.Send(request);

// Receive socks5 proxy response
byte[] response = new byte[1024];
int bytesRead = proxySocket.Receive(response);

// Handling socks5 proxy responses
// …

// Close the proxy connection
proxySocket.Close();
}
}
“`
The above example demonstrates how to implement socks5 proxy connection in C# using Socket class. In this way, we can easily implement socks5 proxy functionality in C# program to provide better security and reliability for network communication.

socks5 proxy udp

In addition to supporting TCP data transmission, socks5 proxy can also realize the proxy forwarding of UDP data. In the actual network communication, sometimes we also need to transfer data via UDP protocol, then you can use socks5 proxy to realize the secure transmission of UDP data.

"`csharp
// Create a UDP proxy connection
Socket udpProxySocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
udpProxySocket.Connect(proxyServer, proxyPort);

// Send UDP data
byte[] udpData = { /* UDP Data contents */ };
udpProxySocket.Send(udpData);

// Receive UDP data
byte[] udpBuffer = new byte[1024];
int udpBytesReceived = udpProxySocket.Receive(udpBuffer);
“`
With the above code example, we can see how to use UDP protocol with socks5 proxy for data transfer in C# program. This provides us with more options in network communication, makes data transmission more flexible and efficient, and also improves the security and reliability of network communication.
