how to return anonymous type from method https://stackoverflow.com/questions/59874640/resolving-an-anonymous-type

ReturnAnonymousType.cs

public class MyController 
{
	public object Get(string id)
	{
		return new { Key = id, Value = "val:" + id };
	}
}
class Program
{
	// Application entry-point
	static void Main()
	{
		var sut = new MyController();

		// Act.
		dynamic res = sut.Get("42");

		// Second attempt:
		var a = new { Key = "", Value = "" };
		a = Cast(a, res);  // <- the code works

		Console.WriteLine($"{a.Key} {a.Value}");
	}

	private static T Cast<T>(T typeHolder, object x)
	{
		// typeHolder above is just for compiler magic
		// to infer the type to cast x to
		return (T)x;
	}
}
