An enumeration of one?
Having something enumerable is the gateway to all LINQ’s loveliness.
But sometimes you have just one object.
So how do you make that enumerable?
var people = new Person[] {person};
Not exactly hard huh?
In fact you can simplify this even more, you can replace new T[] with just new [] like this:
var people = new [] {person};
And the compiler will infer the type of the array for you.
At this point you can start treating your object as a enumeration, and gain all the benefits of the collection monad, not least of which is delayed execution.
var results = from x in new [] {person}
select DoSomethingPrettyCPUIntensive(x);
And notice the expensive operation is only executed if someone actually enumerates the results.
