Question

I read that, for the newest Java, Javascript on Java can call or import java packages easily. In the newest .NET, can JScript.net call C# functions easily?

For details, I am asking not about compiled JScript.net code, but about non-compiled JScript.net string code which is run on the script engine.

Answer 1

Here is an example:

1) CS file with a simple calls and method that returns a string.
2) js file that calls the CS method using eval.

// cstest.cs – compile as library

using System;
namespace MyNamespace
{
    public class Foo
    {
        public string Bar()
        {
            return "Hello JS";
        }
    }
}

// test.js – compile as exe
// add a reference to cstest.dll
// command line compile jsc /t:exe /r:cstest.dll test.js

import MyNamespace;

var o : JSApp = new JSApp();
o.DoEval();

class JSApp
{
    function DoEval()
    {
        var f : Foo;
        var s : String
       eval("f = new Foo;");
       eval("s = f.Bar();"); // call Foo.Bar
       print(s);
    }
};
