HttpListener implements IDisposable but there is not Dispose() method, why and how can I dispose it?

#region Assembly System.Net.HttpListener, Version=8.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51
// C:\Program Files\dotnet\packs\Microsoft.NETCore.App.Ref\8.0.2\ref\net8.0\System.Net.HttpListener.dll

you could cast it to IDisposable first and then dispose it, some classes hide their implementation of Dispose for one reason or another IE (_listener as IDisposable).Dispose() or ((IDisposable) _listener).Dispose()

Any particular reason you're trying to dispose it manually instead of a using block/statement?

I am using 1 HttpListener for all incoming connection, so I am trying to do same things like HttpClient re-using I mean any way I found the way to do: this class contains Close() method which is pretty-much an alias for Dispose()

private readonly HttpListener _listener;
private _isDisposed = false;


public void Dispose()
{
    Dispose(true);
    GC.SuppressFinalize(this);
}

protected virtual void Dispose(bool disposing)
{
    if (_isDisposed)
    {
        return;
    }

    if (disposing)
    {
        // free managed resources
        _listener.Close();
    }

    _isDisposed = true;
}

private readonly HttpListener _listener;
private _isDisposed = false;


public void Dispose()
{
    Dispose(true);
    GC.SuppressFinalize(this);
}

protected virtual void Dispose(bool disposing)
{
    if (_isDisposed)
    {
        return;
    }

    if (disposing)
    {
        // free managed resources
        _listener.Close();
    }

    _isDisposed = true;
}
