Rx Question: Why Observable.Subscribe(OnNext, OnError, OnCompleted) did not reach to OnError ???

Question

I have the following code, but I don't understand why it didn't print out the exception message to the console or it didn't reach to the OnError method. Would you please help!

Thanks

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Reactive.Linq;

namespace UsingSubcribe
{
    class Program
    {
        static void Main(string[] args)
        {
            //make an array of numbers 
            var numbers = from number in new int[] { 1, 2, 0, 3 } select 10/number;
            //make an observable sequence out of those numbers
            var observable = numbers.ToObservable();
            //use the ObservableExtention.Subscribe to callbacks
            observable.Subscribe(OnNext, OnError, OnCompleted);
            Console.ReadLine();
        }
        //Call each time a value from the observable sequence is processed
        static void OnNext(int number)
        {
            Console.WriteLine(number);
        }
        //Call if the processing of the observable sequence throw exceptions
        static void OnError(Exception exception)
        {
            Console.WriteLine(@"Oops ""{0}""", exception.Message);
        }
        //Call if all values in the observable sequence have been processed
        static void OnCompleted()
        {
            Console.WriteLine("I'm done!");
        }
    }
}

Hello,

Your question seems to be relative to Rx , but there is a forum dedicated to Rx

http://social.msdn.microsoft.com/Forums/en-US/rx/threads

I will move your thread towards this forum which is not easy to find .It belongs to the Data Platform development

PS : you have asked the same question ( answered 3 hours ago ) in

http://social.msdn.microsoft.com/Forums/en-US/rx/thread/a0136ce5-542c-4ad9-a3d5-0296c48618a7/#051b224c-4b66-4be2-a4b8-cee310a992f3

Please, avoid to ask the same question on several forums : a moderator has to do a move to send your thread in the good forum and now another moderator will have to do a merge...

The moves/merges are usual for moderators but , in this case , it is annoying because a moderator will have to a merge to avoid to let a thread dying...
