Hi,
Multiple exceptions can't occur at once but if you are referring to multiple types of exception , then System.Exception class is the parent class of all exception. A simple try catch like below is good enough to handle any kind of exception.
try
      {
          //main logic
      }
      catch (Exception ex)
      {
           Console.WriteLine("Error:" + ex.Message);
      }

Hi Anand,
static void Sample(string[] args)
        {
            try
            {
                //Your Code
            }
            catch (Exception ex)
            {
                if (ex is FormatException || ex is OverflowException)
                {

                    Console.WriteLine("Error:" + ex.Message);
                }
                throw;
            }



        }

Hello Anand SA,

Please check the below code...
try { ... }
catch (Exception e) when (e is ArgumentNullException || e is FormatException) { ... }

add this to your program.cs or startup.cs or Global.asax
AppDomain.CurrentDomain.FirstChanceException += (sender, eventArgs) =>
{
    Debug.WriteLine(eventArgs.Exception.ToString());
};
It will show every exception in your application.

Catch System.Exception and switch on the types
catch (Exception ex)
{
    if (ex is FormatException || ex is OverflowException)
    {
        WebId = Guid.Empty;
        return;
    }
    throw;
}
