在C#中,使用TcpClient連接池可以提高應(yīng)用程序的性能,減少頻繁創(chuàng)建和關(guān)閉連接所產(chǎn)生的開銷
TcpConnectionPool
。這個類將包含一個ConcurrentBag<TcpClient>
來存儲空閑的TcpClient對象。同時,我們還需要一些配置參數(shù),例如最大連接數(shù)、最小連接數(shù)等。public class TcpConnectionPool : IDisposable
{
private readonly ConcurrentBag<TcpClient> _connections = new ConcurrentBag<TcpClient>();
private readonly SemaphoreSlim _semaphore;
private readonly string _host;
private readonly int _port;
public TcpConnectionPool(string host, int port, int minConnections, int maxConnections)
{
_host = host;
_port = port;
_semaphore = new SemaphoreSlim(maxConnections, maxConnections);
for (int i = 0; i < minConnections; i++)
{
_connections.Add(CreateNewConnection());
}
}
// ...
}
public async Task<TcpClient> GetConnectionAsync()
{
await _semaphore.WaitAsync();
if (_connections.TryTake(out var connection))
{
return connection;
}
return CreateNewConnection();
}
private TcpClient CreateNewConnection()
{
var client = new TcpClient();
client.Connect(_host, _port);
return client;
}
ReleaseConnection
方法,將連接放回空閑連接集合中。public void ReleaseConnection(TcpClient connection)
{
if (connection != null && connection.Connected)
{
_connections.Add(connection);
}
_semaphore.Release();
}
IDisposable
接口,以便在不再需要連接池時正確地關(guān)閉所有連接并釋放資源。public void Dispose()
{
foreach (var connection in _connections)
{
connection?.Close();
}
_semaphore.Dispose();
}
現(xiàn)在,你可以在你的應(yīng)用程序中使用TcpConnectionPool
類來管理TcpClient連接。請注意,這只是一個簡單的實現(xiàn),你可能需要根據(jù)你的需求進(jìn)行調(diào)整和優(yōu)化。例如,你可以添加連接超時、連接健康檢查等功能。
