InvokeGet on an instance field works, while it fails on static field.

[PiotrZierhoffer]

As a first note, I work on mono, not the very newest version from git, but quite new. I may test it on other versions as well, but I will have problems testing it on .NET.

Wiki tells us, that InvokeGet is for properties, yet I see it works with instance fields as well.

So this works:

var value = Dynamic.InvokeGet(target, "myField");

but this does not:

var context = InvokeContext.CreateStatic(target.GetType());
var value = Dynamic.InvokeGet(context, "myStaticField");

It fails with:

Microsoft.CSharp.RuntimeBinder.RuntimeBinderException:
`TargetType` does not contain a definition for `get_myStaticField`.

Am I doing something wrong or is it a bug?

Yeah, I had to hoodwink it on Mono to get it to work for static properties, my guess is because it isn't something the csharp compiler would ever do with the API that it's a little nebulous.

I'm honestly not sure if it works on windows it works for Static fields, if it does, it might make sense to add some tests and switch mono to reflection for static properties and fields, just to keep the behavior the same.

I'll try to test it somehow on .NET.

Is there another method to access fields via Dynamitey?
Just as a side note, Dynamitey rocks ;] That's just how I'd like to use reflection.

Ok, I was able to test it on .NET 4.5. No luck, unfortunately, with the following code:

namespace Test1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine(Dynamic.InvokeGet(new ToTest(), "field")); //prints 16
            var context = InvokeContext.CreateStatic(typeof(ToTest));
            Console.WriteLine(Dynamic.InvokeGet(context, "other")); //fails with
                                                                      // RuntimeBinderException
        }       
    }

    class ToTest
    {
        private int field = 16;
        private static int other = 17;
    }
}

The exception is

'Test1.ToTest' does not contain a definition for 'other'

Will you address this issue or should I hack it for my app via reflection?

[jbtule]

Very low priority for me addressing it, these are wrappers around the DLR api, the only way for me to address it is to test if there exist a field when it fails and then use reflection.
