Using C# as a scripting language

Question

Currently I am writing a game using C# and OpenTK, and I would like to implement scripting. I've tried LuaInterface, but whenever I passed parameters to arguments there was some sort of memory leak, and the total memory usage increased by between 0.02 and 0.05 MB per second, which is unacceptable. I would really love if I could implement C# as a scripting language. So far I have compiling from a source file implemented, but whenever I go to load the main module so I can retrieve the methods I would need, no methods are found. This is my entire Script class:

private Assembly asm;

public Script(string path) {
    CodeDomProvider provider = CodeDomProvider.CreateProvider("C#");
    ICodeCompiler compiler = provider.CreateCompiler();
    CompilerParameters param = new CompilerParameters();
    param.GenerateInMemory = true;
    CompilerResults result = compiler.CompileAssemblyFromFile(param, path);
    if (result.Errors.Count > 0) {
        Console.WriteLine("Errors:");
        foreach (CompilerError err in result.Errors) {
            Console.WriteLine(string.Format("{0}:{1} - {2}", err.Line, err.Column, err.ErrorText));
        }
    }

    asm = result.CompiledAssembly;
}

public void Init() {
    foreach (var m in asm.GetLoadedModules()) {
        Console.WriteLine(m.Name);
        foreach (var me in m.GetMethods()) {
            Console.WriteLine("m: " + me.Name);
        }
    }
    // MethodInfo mi = asm.GetLoadedModules(false)[0].GetMethod("Init");
    // mi.Invoke(null, null);
}

And this is my script I am trying to compile:

using System;

namespace FactionScripting {
    public class Test {
        public void Init() {
            Console.WriteLine("Initialized.");
        }
    }
}

Answer 1

Never mind, I found where the methods I need are (and it makes a lot of sense now that I found them). I need to go into the types inside of the module and then I can get the methods.

Hi blakpilar,

Thanks for sharing your solutions here.
