[Mono-dev] Mono.CSharp.Evaluator: x.GetType Bug?

[lukebuehler]

No that doesn't work.

1. Your code gives me the same exception
2. A quick look with reflector shows me that eval.Run is just a wrapper
over eval.Evaluate.
3. To prove it, this works:
    evaluator.Evaluate("class A{ public int X;}", out result, out set);
    evaluator.Evaluate("var a = new A{X=10};", out result, out set);
    evaluator.Evaluate("var b = new A{X=20};", out result, out set);
    // this prints 30 without an exception
    evaluator.Evaluate("print(a.X+b.X);", out result, out set);

It's only the GetType call that trips up the compiler.

Cheers
