we could invoke and process the data from Main() as follows:

Array objs = GetProjectedSubset();

foreach (object o in objs)

{

Console.WriteLine(o);  // Calls ToString() on each anonymous object.

}

Note that we have to use a literal System.Array object and cannot make use of the C# array

declaration syntax, given that we don’t know the underlying type of type! Also note that we are not

specifying the type parameter to the generic ToArray() method, as we (once again) don’t know

the underlying data type until compile time (which is too late for our purposes).

The obvious problem is that we lose any strong typing, as each item in the Array object is

assumed to be of type Object. Nevertheless, when you need to return a LINQ result set which is the

result of a projection operation, transforming the data into an Array type (or another suitable con-

tainer via other members of the Enumerable type) is mandatory.
