Cloning anonymous types?

Question

What I want to do is pass IEnumerable to the method and return an IEnumerable instance to it. However, I want each collection to be a copy, and not just a copy that is a copy.

Example:

// some random data from L2S
var data = (from p in sourceData
           select new
           {
               a = 1,
               b = "hello",
           }).ToArray();

var dataCopy = data.Copy(); // somehow i want 'dataCopy' to be a deep copy of 'data'

foreach (var d in dataCopy)
{
    // alter the item in the collection somehow
    d.b = d.b + "1";
}

// combine both sets of data
var finalData = data.Union(dataCopy);

Thus, the collection 'finalData' has twice as many elements as 'data' or 'dataCopy'. Thus, all parameters “b” in “dataCopy” are added to the end, but since they still refer to objects in “data”, all parameters “b” in “data” also have “1” added to the end.
