Is there a way to convert a dynamic or anonymous object to a strongly typed, declared object?

Question

If I have a dynamic object, or anonymous object for that matter, whose structure exactly matches that of a strongly typed object, is there a .NET method to build a typed obj

Answer 1

You could serialize to an intermediate format, just to deserialize it right thereafter. It's not the most elegant or efficient way, but it might get your job done:

Suppose this is your class:

// Typed definition
class C
{
    public string A;
    public int B;
}

And this is your anonymous instance:

// Untyped instance
var anonymous = new {
    A = "Some text",
    B = 666
};

You can serialize the anonymous version to an intermediate format and then deserialize it again to a typed version.

var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
var json = serializer.Serialize(anonymous);
var c = serializer.Deserialize(json);

Note that this is in theory possible with any serializer/deserializer (XmlSerializer, binary serialization, other json libs), as long as the roundtrip is symmetric.
