Compile run-time C# Script with existing type

Question

I am not really sure that i am picked right title. But here i will try to explain the details what i want to do.

Currently I am developing simple 2d game engine for my own game. Let's say i have 4 classes:

• Scene and SceneObject: There is SceneObject[] Objects variable in Scene class which represent Objects in Scene (SceneObject could be a text, image, button etc. For text it will be SceneObject.Text, for image it will be SceneObject.Image and so on).
• ContentManager: The class that handle image source for SceneObject.Image, all Image is stored in this class (Where "Image" is System.Drawing.Image type)
• Log: Simple Class to logging

What i want is Loading the SceneObject from C# Script, but in that script, i want to allow the script writer to interact with ContentManager (and all classes that may i made in my project, like the Log class)

Here the example of C# Code that to be compiled in Run-time (let's say its called "ExampleScript.cs"):

using System;
using System.Collections.Generic;
using System.Text;

using Engine.Graphics;
using Engine.UI;

namespace Engine
{
    public class Example : Scene
    {
        public SceneObject.Button BtnExample;
        public SceneObject.Text LblExample;
        public Example()
        {
            // This will throw an exception if Example.png isn't exist in the ContentManager
            BtnExample = new SceneObject.Button(ContentManager.GetImage("Example.png"));
            LblExample = new SceneObject.Text("Hello World!");

            // This is the plus for C# Run-Time Code
            // Allow writer to add customization for each SceneObject
            BtnExample.Rotate(10);
            BtnExample.Color = Color.White;
            // and so on
            // I believe complicated effect / customization can be done easier than loading from plain text file (and it's somehow look cooler LOL)

            // Add it to "Objects" variable
            Add(LblExample, BtnExample);
            Log.WriteLine("SceneLoaded!");
        }
    }
}

and then i compile and get all SceneObject like this:

try
{
    Script SceneScript = new Script("ExampleScript.cs");
    Scene Example = SceneScript.Compile();
    SceneObject[] Objects = Example.Objects;
}
catch (Exception ex)
{
    // Compile Error here
    // Something like "'Example.png' isn't exist in content manager"
}

So how can i do this?

I tried to search on Google, but what i found is just something like compiling console application in run-time, that's not enough for me :\

Thanks in advance! :D

I would recommend looking at the CS-Script library. In particular, take a look at their documentation around the 'type-sharing' pattern, which I think will do exactly what you are looking for (albeit you need to use their runtime library to do it)
