error running the ExpandoObject example

[lynnmiller]

I am trying to get the examples running from your website. I have been successful getting 3 of 4 working. The only one not working is the ExpandoObject example.

Here is my code:

        // using Z.Expressions; // Don't forget to include this.
        int result1 = Eval.Execute<int>("X + Y", new { X = 1, Y = 2 });
        Console.WriteLine(result1);

        // using Z.Expressions; // Don't forget to include this.
        int result2 = Eval.Execute<int>("{0} + {1}", 1, 2);
        Console.WriteLine(result2);

        // using Z.Expressions; // Don't forget to include this.
        dynamic expandoObject = new ExpandoObject();
        expandoObject.X = 1;
        expandoObject.Y = 2;
        int result3 = Eval.Execute<int>("X + Y", expandoObject);
        Console.WriteLine(result3);

        // using Z.Expressions; // Don't forget to include this.
        string s = "X + Y";
        int result4 = s.Execute<int>(new { X = 1, Y = 2 });
        Console.WriteLine(result4);

        Console.ReadKey();

Here is my error:

-System.InvalidOperationException: 'The binary operator Add is not defined for the types 'System.Object' and 'System.Object'.'

I am using the evaluation version 2.4.3

Hello @lynnmiller ,

Sorry for the delay, it took us a little bit more time than expected to fix this one.

The v2.4.4 has been released.

Let me know if you can now run example successfully.

Best Regards,

Jonathan

No problem about the delay. I tested it and it works. Thanks!
