How to call a function written in javascript file with C # using IronJS

Question

I just load Iron JS and after executing some 2/3 simple programs using the Execute method, I study the ExecuteFile method.

I have a Test.js file whose contents are equal

function Add(a,b)
{
    var result = a+b;
    return result;
}

I want to use the same from C # using Iron JS. How can i do this? My code is bye

var o = new IronJS.Hosting.CSharp.Context();
dynamic loadFile = o.ExecuteFile(@"d:\test.js");
var result = loadFile.Add(10, 20);

But the loadfile variable is null (the path is correct).

How to call JS function, please help ... Also google search did not give any help.

thank

The result of the execution will be empty, since your script returns nothing.

"globals" script .

var o = new IronJS.Hosting.CSharp.Context();
o.ExecuteFile(@"d:\test.js");
dynamic globals = o.Globals;

var result = globals.Add(10, 20);

EDIT:. , , NuGet. , IronJS 0.2.0.1:

var o = new IronJS.Hosting.CSharp.Context();
o.ExecuteFile(@"d:\test.js");
var add = o.Globals.GetT<FunctionObject>("Add");

var result = add.Call(o.Globals, 10D, 20D).Unbox<double>();
