The following example demonstrates starting a simple agent with one variable.

{
    //Add a variable to the agent
    agent1.Variables.Add(agent1.Mib.GetByNodeName(NodeName.sysContact).GetIid(),
        agent1.Mib.CreateVariable(NodeName.sysContact, "Systems Admin"));

    //Start listening for requests
    agent1.Start(agent1_MessageReceived, null);
}

private void agent1_MessageReceived(Agent agent, RequestMessage request, object state)
{
    //Create and send a response whenever a request is received
    agent1.Send(agent1.CreateResponse(request), request.Origin);
}

Visual Basic

Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs)
    'Add a variable to the agent
    agent1.Variables.Add(agent1.Mib.GetByNodeName(NodeName.sysContact).GetIid(), agent1.Mib.CreateVariable(NodeName.sysContact, "Systems Admin"))

    'Start listening for requests
    agent1.Start(AddressOf agent1_MessageReceived, Nothing)
End Sub

Private Sub agent1_MessageReceived(ByVal agent As Agent, ByVal request As RequestMessage, ByVal state As Object)
    'Create and send a response whenever a request is received
    agent1.Send(agent1.CreateResponse(request), request.Origin)
End Sub
