How to set Connection: Keep-Alive in C# HttpWebRequest class ?

Cannot set by: webrequest.KeepAlive = true;
Have to set this request header by reflection
var req = (HttpWebRequest)WebRequest.Create(someUrl);

var sp = req.ServicePoint;
var prop = sp.GetType().GetProperty("HttpBehaviour", BindingFlags.Instance | BindingFlags.NonPublic);
prop.SetValue(sp, (byte)0, null);
