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.GetHostEntry(host);

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

EndPoint ep = (EndPoint)iep;

Socket sock = new Socket(ep.AddressFamily, SocketType.Dgram,
ProtocolType.Udp);


sock.SetSocketOption(SocketOptionLevel.Socket,
SocketOptionName.ReceiveTimeout, 1000);

sock.Connect(iep);


sock.SendTo(packet, snmplen, SocketFlags.None, iep);

//Receive response from packet

try

{

packet = new byte[1024];

int recv = sock.ReceiveFrom(packet, ref ep);


//here I am getting above written exceptions

catch (SocketException ex)

{

packet[0] = 0xff;

}

pls help me out of this its very urgent.
thanks
alok sengar

have you tried using a bigger timeout value?
