.NET Network Monitor

Introduction

I need to monitor Network status in my project.To check the cable has bad contact or not and to check network is enable or not.So I develop a simple tool to test.
Background

This sample is using WMI to get information in .NET.
Using the Code 

I use a singleton to manager all network information. Now, call this code to initialize and monitor:

NetworkManager.Instance.StartMonitor();

And foreach NetworkManager.Instance.Informations.Values to get information:

foreach(NetworkInfo info in NetworkManager.Instance.Informations.Values)
{
    Console.WriteLine("Device Name:" + info.DeviceName);
    Console.WriteLine("Adapter Type:" + info.AdapterType);
    Console.WriteLine("MAC Address:" + info.MacAddress);
    Console.WriteLine("Connection Name:" + info.ConnectionID);
    Console.WriteLine("IP Address:" + info.IP);
    Console.WriteLine("Connection Status:" + info.Status.ToString());
}

At last call this to destory:

NetworkManager.Instance.Destory();

Abort the Code

public enum NetConnectionStatus
{
    Disconnected = 0,
    Connecting = 1,
    Connected = 2,
    Disconnecting = 3,
    HardwareNotPresent = 4,
    HardwareDisabled = 5,
    HardwareMalfunction = 6,
    MediaDisconnected = 7,
    Authenticating = 8,
    AuthenticationSucceeded = 9,
    AuthenticationFailed = 10,
    InvalidAddress = 11,
    CredentialsRequired = 12
}

First, this enum named NetConnectionStatus that is reference from the property NetConnectionStatus in Win32NetworkAdapter class.
