Linq: The Missing ToDictionary Extension Method Overload
http://weblogs.asp.net/ okloeten/ archive/ 2008/ 04/ 22/ 6121417.aspx
Enumerating over a Dictionary<TKey, TValue> you will get structs of type KeyValuePair<TKey, TValue>. Whenever you use the ToDictionary extension method, you are forced to specify how to get the key and value for each item, even if it's an enumeration of KeyValuePairs. Seems a bit redundant, doesn't it? public static Dictionary<TKey, TValue> ToDictionary<TKey, TValue>(this IEnumerable<KeyValuePair<TKey, TValue>> enumeration) { // Check to see that enumeration is not null if (enumeration == null) throw new ArgumentNullException("enumeration"); return enumeration.ToDictionary(item => item.Key, item => item.Value); } Well, that little bit of code settles that.
