udpclient.receive（）突然停止接收

Question

I'm using UdpClient to receive data from a single host(actually it's a microcontroller that sends 32 bytes of data every 4 milliseconds.
The program I wrote is pretty simple.
I'm initializing the UdpClient like this(in Program.cs):

public static UdpClient client = new UdpClient(1414);

after that i do this in Form_Load event:

static UdpClient client = Program.client; 
IPEndPoint RemoteIpEndPoint = new IPEndPoint(IPAddress.Any, 0);

and then call the client.Recieve() like this:

                Task.Run(() =>
                {
                    while (true)
                    {                       
                        try
                        {
                            data = client.Receive(ref RemoteIpEndPoint);                            
                        }
                        catch (Exception ex)
                        {
                            String err_type = ex.GetType().Name;
                            if (err_type == "SocketException")
                            {                                    
                                MessageBox.Show("Cannot Find The Device.", "Device Error.");
                            }
                        }                                                        
                    }
                });

the program runs fine on my own system (using Windows 10). However when i run this program on windows 7,at random times,but with 100% chance client.Recieve() stops working and the program no longer receives any data. no exception is thrown. to find the root of the problem, I installed Wireshark to test if there is any incoming data.The answer was no(the LAN port light stops blinking too) . What has me confused is that this does not happen on windows 10.

The thing is, you miss all exceptions except SocketException. To find out, what's going on, please, rewrite your catch block:

Task.Run(() =>
                {
                    while (true)
                    {                       
                        try
                        {
                            data = client.Receive(ref RemoteIpEndPoint);                            
                        }
                        catch (SocketException ex)
                        {

                                MessageBox.Show("Cannot Find The Device.", "Device Error.");

                        }  
                        catch (Exception e)
                        {
                                MessageBox.Show(e.GetType().Name, e.Message);
                        }

                    }
                });

Turns out my code was completely fine.
This was a hardware problem on our side.
