IObserver<T>.OnError Method (Exception)
Notifies the observer that the provider has experienced an error condition.
Assembly: mscorlib (in mscorlib.dll)
Although error is an object that is derived from System.Exception, it does not necessarily represent an exception that is thrown by the provider. It can also represent a routine or expected error condition, such as data that is missing or unavailable. The method should be seen as informational, and the provider should not expect the observer to provide error handling.
