I have found this custom extension method to be extremely useful when working with linq:
public static IEnumerable<T> Cast<T>(this object value) { var enumerableOfTValue = value as IEnumerable<T>; if (enumerableOfTValue != null) return enumerableOfTValue; var enumerableValue = value as IEnumerable; if (enumerableValue != null) return Enumerable.Cast<T>(enumerableValue); return Enumerable.Cast<T>(new[] { value }); }
Basically it lets you turn any object into an IEnumerable<T>. Its especially handy when working with an object and you don’t know if it’s a single object or a set.
