@jagregory I don't like it, not enough job security
Small correction to @robashton's extension because ICollection
doesn't have AddRange
:
using System.Collections.Generic;
public static class IEnumerableExtensions
{
public static void AddTo<T>(this IEnumerable<T> self, List<T> destination)
{
if(self != null) destination.AddRange(self);
}
}
@leniel How do you call this extension method on self
if self
is null
? It seems like it would cause some exception))

@jagregory collection.CheckIfThisIsNullAndIfThisIsNotAddTheItemsInTheCollectionToMe(items); [Something Neil might write ;) ]
