SingleOrDefault(IEnumerable, TSource) Returns the only element of a sequence, or a specified default value if the sequence is empty; this method throws an exception if there is more than one element in the sequence.

Any idea why IList doesn't inherit from ICollection? Since the latter is basically IEnumerable plus Count, and since IList already katışıksız a Count method, having IList inherit ICollection wouldn't have required any more work for implementers, but would C# ReadOnlyCollectionBase Nasıl Kullanılır have allowed someone with an IList to know how many items to expect from an enumeration.
