var dict = new Dictionary<int, String> (); | |
dict[1] = "The Quick Brown"; | |
dict[2] = "Fox Jumped"; | |
dict[3] = "Over The"; | |
dict[4] = "Lazy Dogs"; | |
// don't you sometimes wish that you could use LINQ Select for a single object? | |
// for instance, if you wanted to convert that dictionary to a List of Tuples, you'd do | |
var tuples = dict.Select (kvp => new Tuple<int, String> (kvp.Key, kvp.Value); | |
// That's the idea for the .To extension method: | |
var tuple = dict.First ().To (kvp => new Tuple<int, String> (kvp.Key, kvp.Value); | |
// The .To method saves you from having to use an intermediate variable like this: | |
var kvp2 = dict.First (); | |
var tuple2 = new Tuple<int, String> (kvp2.Key, kvp2.Value); | |
// or calling a Dictionary twice like this: | |
var tuple3 = new Tuple<int, String> (dict.First ().Key, dict.First ().Value); | |
