Log exception to file in c# .net core application explained

In production environment when any bug gets reported at that time as developer wants to get the exception details of bug to resolve the issue on high priority.
In some case there might be situation where exception is not logged in table but developer wants to check the bug immediately. for that purpose we need to write the
exception details including stack trace of bug in file. To implement this easily i am going to demonstrate the implementation of custom logging in file as below.

First we need to construct the exception and logger method in custom logger class as shown below.


public class CustomLogger { public static List<string> ConstructExceptionDetails(Exception ex,string FunctionName) { return new List<string>() { $"{DateTime.Now} - {FunctionName}", $"Exception: {ex.Message}", $"StackTrace: {ex.StackTrace}", $"InnerException: {ex.InnerException?.…

How to ping Azure VM using C# code explained

I was looking for the code which can ping the Azure VM and give me the details whether VM is UP or down since the ICMP protocol is not permitted through the Azure load balancer,
you will notice that you are unable to ping an Azure VM from the internet, and from within the Azure VM, you are unable to ping internet locations.

To get rid of the issue i digged the internet to get the solution so finally i got the below solution which I have contructed through the function,
below function will ping the azure vm machine and returns true if online or false if offline

  public static bool PingServerWithSocket(string iporHostname,int portNo)
        {
            bool result = false;
           
                try
                {
                    var sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
                    sock.Blocking = true;
                   

                    IPAddress ipaddes = Dns.GetHostEntry(iporHostname).AddressList[0];
                    sock.Connect(ipaddes, portNo);
                    result = true;
                }
                catch
                {

                    result = false;
                }
           

            return result;
        }


Hope this example will help to those who wants to ping the azure VM
