Create a dynamic type from a string in C#

Question

My question is very, very simple about C#:

We can create a dynamic type with the syntax:

dynamic dObj = new { P1 = "a", P2 = 1, p3 = DateTime.Now };

For the same result, is there any way to create that object from a string variable? like:

string sObj = @"new { P1 = "a", P2 = 1, p3 = DateTime.Now }";
dynamic dObj = [something].fromstring(sObj);

The idea is to get a object from a object built from a string, or I need a serializer to that?

Answer 1

That requires a compiler. The ExpandoObject class pretty much does what you want:

    dynamic bag = new ExpandoObject();
    bag.P1 = "a";
    bag.P2 = 1;
    bag.p3 = DateTime.Now;

Which also solves a problem with your original code, the members of an anonymous type only have internal accessibility. In other words, your dObj object is only usable in code that lives in the same assembly.
