Event Receivers: Delete all event receivers associated to a list

scenario: How to delete all the event receivers associated to a list?

Approach:

List eventreceivers = new List();

foreach (SPEventReceiverDefinition EventReceiver in list.EventReceivers)
{
   eventreceivers.Add(EventReceiver);
}

foreach (SPEventReceiverDefinition er in eventreceivers)
{
   er.Delete();
}

Note: We can not have only 2nd foreach loop alone. The current list of event receivers associated to a list gets updated everytime a delete operation is performed. So, an exception will be raised if you use only delete operation.
