PowerSNMP for .NET |
| Dart.PowerSNMP Namespace > Agent Class > Open Method : Open(Int32) Method |
Enables the Agent by binding it to a network address. Events will be raised when SNMP packets are received.
| Exception | Description |
|---|---|
| SocketException | A problem was experienced creating a Socket or binding it to the host/port specified. |
| InvalidOperationException | Agent.Socket is already open. |
The Agent cannot communicate until Open is called. Once called, Agent.Socket returns the Socket in use. Agent.Close should be used to release socket resources.
The SNMP Agent "well-known" port is 161. Managers must be configured to contact this agent on this port if the "well-known" value is not used.The following example demonstrates opening and closing the Agent component.
[Visual Basic]
Private Sub cmdStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdStart.Click
If (cmdStart.Text = "Start Agent") Then
'Start the Agent
Try 'Open port for receiving requests and sending responses
Agent1.Open()
cmdStart.Text = "Active"
Catch ex As Exception
ShowError(ex.Message)
End Try
Else
'Close Agent
Agent1.Close()
cmdStart.Text = "Start Agent"
End If
End Sub
[C#]
private void cmdStart_Click(object sender, System.EventArgs e)

agent1.Open();
cmdStart.Text = "Active";
}
catch (Exception ex)
{
ShowError(ex.Message);
