　　class Program

　　{

　　static void Main(string[] args)

　　{

　　var apiKey = "your_api_key";

　　var secretKey = "your_secret_key";

　　var client = new BinanceClient(apiKey, secretKey);

　　var symbol = "BTCUSDT"; // Replace with your desired cryptocurrency pair

　　// Connect to the Binance API

　　client.Start();

　　// Subscribe to the price data stream

　　client.PriceUpdate += (sender, e) =>

　　{

　　Console.WriteLine($"Price: { e.Price}, Quantity: { e.Quantity}");

　　};

　　Console.WriteLine("Press any key to exit...");

　　Console.ReadKey();

　　// Disconnect from the Binance API

　　client.Stop();

　　}

　　}

　　```

　　5. Run the Program
