A bug.

[treenewlyn]

JS Code:

show(Add(123,4));

C# code:
static void Print(object value)
{
MessageBox.Show(value.ToString());
}
static double Add(double x, double y)
{
return x + y;
}

And..... I changed the source with this:

    [Serializable]
    public class TestClass : IronJS.Hosting.CSharp.Context
    {
        private static readonly Type UtilsType = typeof(IronJS.Native.Utils);
        private static readonly System.Reflection.MethodInfo CreateFunctionMethod = UtilsType.GetMethod("CreateFunction", System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Static);
        private delegate FunctionObject CreateFunctionHandler<T>(IronJS.Environment env, int? length, T @delegate);

        public void SetFunction<T>(string name, T @delegate)
        {
            var d = Delegate.CreateDelegate(typeof(CreateFunctionHandler<T>), CreateFunctionMethod.MakeGenericMethod(typeof(T))) as CreateFunctionHandler<T>;
            var f = d(this.Environment, null, @delegate) as FunctionObject;
            this.SetGlobal(name, f);
        }
    }

.......

NOW.

 var c = new TestClass();
        context = c;
        context.CreatePrintFunction();
        context.Environment.BreakPoint = breakPoint;

        c.SetFunction("Add", new Func<double, double, double>(Add));
        c.SetFunction("show", new Action<object>(Print));

It's so easy.

Oh, the bug is display Text:

MessageBox.Show("IronJS.BoxedValue");

[treenewlyn]

I must change the Print method:
But,It's ugly.

static void Print(object value)
{
if(value is BoxedValue)
{
value = ((BoxedValue)value).ClrBoxed;
}
MessageBox.Show(value.ToString());
}

What is the actual bug/issue here? Not following your code/logic at all.

[treenewlyn]

In the javascript code:

ClrFunction1(ClrFuntion2());

the ClrFunction1 argument is a BoxedValue.
But i want the ClrFuntion2() Value.

There is currently no support for passing delegates directly into IronJS, they have to be wrapped as HostFunctionObject instances, check this https://github.com/fholm/IronJS/wiki/Exposing-a-CLR-function-as-a-native-JavaScript-function post on the wiki for reference.

The second:

If the C# has a Method like this:

static void ClrInvokeJS(Action s)
{
s("Hello");

}

Now, I register this Method to JSFunction.

In the jsCode,I wan :

function jsfunctionTest(s)
{
print(s);
}

ClrInvokeJS(jsfunctionTest);

Of course, Compile failed now. But this is a good support ideas!

[treenewlyn]

Oh ,sorry. The second is support!!

    static void ClrInvokeJS(BoxedValue s)
    {
        if(s.IsFunction)
        {
            s.Func.Call(null, "Hello");
        }
       // s("Hello");
    }
