QuickProxyNet

QuickProxyNet is a high-performance C# library for connecting to servers via various types of proxies, providing direct and efficient access to the underlying data stream. It supports a range of proxy protocols, including HTTP, HTTPS, SOCKS4, SOCKS4a, and SOCKS5, enabling seamless integration into .NET applications requiring proxy connections.

Features

• High-Performance Connection Handling: Designed for minimal latency and optimal resource usage, allowing for efficient handling of high-load scenarios.
• Support for Multiple Proxy Types: Connect via HTTP, HTTPS, SOCKS4, SOCKS4a, and SOCKS5 proxies.
• Raw Stream Access: Upon connection, QuickProxyNet provides a raw Stream to directly interact with data, making it highly suitable for applications needing low-level network control.
• Customizable Timeout and Connection Settings: Configure timeouts, connection endpoints, and proxy settings for optimal network performance.

Installation

Clone the repository or install via your preferred NuGet package manager (if available):

dotnet add package QuickProxyNet

Usage

The library offers a ProxyClientFactory class to easily create proxy connections. Here’s a quick guide on how to use it.

Example: Creating a Proxy Client

The following example shows how to create a proxy client using a URI and connect to a remote server through it:

using System;
using System.Net;
using QuickProxyNet;

// URI of the proxy server, including protocol (e.g., "http", "socks5")
Uri proxyUri = new Uri("http://username:password@proxyserver.com:8080");

// Create a proxy client
var client = ProxyClientFactory.Instance.Create(proxyUri);

// Connect to the target server through the proxy and get a raw Stream for direct data access
using (var connectionStream = await client.ConnectAsync("destinationserver.com", 80))
{
    // Work with the Stream directly (e.g., send and receive data)
    // Example: Send HTTP request, work with binary data, etc.
}

Example: Creating a Proxy Client with Custom Configuration

You can also specify the proxy type, host, port, and optional credentials:

using System;
using System.Net;
using QuickProxyNet;

// Define proxy details
ProxyType proxyType = ProxyType.Socks5;
string proxyHost = "proxyserver.com";
int proxyPort = 1080;
NetworkCredential credentials = new NetworkCredential("username", "password");

// Create the proxy client with specified configuration
var client = ProxyClientFactory.Instance.Create(proxyType, proxyHost, proxyPort, credentials);

// Connect to the target server and obtain a raw Stream
using (var connectionStream = await client.ConnectAsync("destinationserver.com", 80))
{
    // Directly work with the Stream for low-level network operations
}

Supported Proxy Types

• HTTP: Standard HTTP proxy with CONNECT support for tunneling.
• HTTPS: Supports SSL/TLS tunneling.
• SOCKS4: Supports IP-based connections only.
• SOCKS4a: Adds support for domain name resolution through the proxy.
• SOCKS5: Full-featured SOCKS proxy with authentication and DNS support.

Configuration Options

Each proxy client supports various configurations to fine-tune network behavior, including:

• WriteTimeout and ReadTimeout: Specify timeouts for data send/receive operations.
• LocalEndPoint: Set a local endpoint for the connection if required.
• NoDelay: Option to disable the Nagle algorithm for reduced latency in data transmission.
• LingerState: Configure linger behavior for connection closure.
