Besides LINQ queries, how to use anonymous types in C #?

I'm trying to speed up work on some of the new features in C #, and one of them, which I did not have the ability to use, is anonymous types.

I understand the use as it relates to LINQ queries and I looked at this SO post which asked a similar question. Most of the examples I've seen on the net are related to LINQ queries, which is great. I saw some somewhat far-fetched examples, but not really where I saw a lot of value.

Do you have a new use for anonymous types where you think it really provides you with some usefulness?

, foreach. (, , , LINQ to Objects.) :

Dictionary<int, string> employees = new Dictionary<int, string>
{
    { 1, "Bob" },
    { 2, "Alice" },
    { 3, "Fred" },
};

// standard iteration
foreach (var pair in employees)
    Console.WriteLine("ID: {0}, Name: {1}", pair.Key, pair.Value);

// alias Key/Value as ID/Name
foreach (var emp in employees.Select(p => new { ID = p.Key, Name = p.Value }))
    Console.WriteLine("ID: {0}, Name: {1}", emp.ID, emp.Name);

I used them to create template letters, as they are great if you use reflection and generics.
