What’s the return type of an anonymous class

I’m creating an anonymous type with query like the following:

Caller code:

 var query= from p in _db.ExecuteDataSet(SQL).Tables[0].AsEnumerable()
                        select new {
                                       ProductCode = p.Field<string>("PRODUCT_CODE"),
                                       ProductName = p.Field<string>("PRODUCT_NAME")
                                   };
 foreach(var product in query)
 {
     WriteProduct(product);
 }

Method is like:

void WriteProduct(object prod)
{
  //   access the product
}

I fail to get the correct Parameter Type for the WriteProduct method. Please help me.

Yes you can.

public class Program
{
    private static void Thing(dynamic other)
    {
        Console.WriteLine(other.TheThing);
    }

    private static void Main()
    {
        var things = new { TheThing = "Worked!" };
        Thing(things);
    }
}

But as a small, minor detail, DON’T!

Anonymous types are anonymous for a reason, they aren’t first class entities in your code, they’re more of a convenience. If a type is that important, define it as such.
