hi,
I have already tried this URL's code
"http://www.java2s.com/Code/CSharp/Network/SimpleSNMP.htm"
but I am getting error when i am creating a UDP type Socket and recieving
packet from this socket.
some time error is---"An existing connection was forcibly closed by the
remote host"
and some time error is---
"A connection attempt failed because the connected party did not properly
respond after a period of time, or established connection failed because
connected host has failed to respond"
i am using this code for

try

{

IPHostEntry ihe = Dns.GetHostEntr y(host);

IPEndPoint iep = new IPEndPoint(ihe. AddressList[0], 161);

EndPoint ep = (EndPoint)iep;

Socket sock = new Socket(ep.Addre ssFamily, SocketType.Dgra m,
ProtocolType.Ud p);
sock.SetSocketO ption(SocketOpt ionLevel.Socket ,
SocketOptionNam e.ReceiveTimeou t, 1000);

sock.Connect(ie p);
sock.SendTo(pac ket, snmplen, SocketFlags.Non e, iep);

//Receive response from packet

try

{

packet = new byte[1024];

int recv = sock.ReceiveFro m(packet, ref ep);
//here I am getting above written exceptions

catch (SocketExceptio n ex)

{

packet[0] = 0xff;

}

Just a quick tip. Next time you have an urgent question, try posting
with a subject that describes the problem. It tends to attract the
right people better than a generic "very urgent" subject.
