Possible to use C# codeDOM to call back to pre-compiled functions?

问题

I'm working on a silly game where the player controls their character by programming procedures for it to follow. I'm using C# codeDOM to compile the code the player writes and I'd like for the player to be able to call functions written into the pre-compiled part of the software. For example:

Player-written code to be compiled at run-time by codeDOM:

namespace AutoCrawl
{
    public class Player
    {
        public void Go_Up()
        {
            Move("Up");
        }
    }
}

My pre-compiled code:

    private void compileUserCode()
    {
        string code = UserCodeTextBox.Text;

        CSharpCodeProvider provider = new CSharpCodeProvider();
        CompilerParameters parameters = new CompilerParameters();

        parameters.GenerateInMemory = true;
        parameters.GenerateExecutable = false;

        CompilerResults results = provider.CompileAssemblyFromSource(parameters, code);
    }

    private void Move(string direction)
    {
        //move the player's character in the direction specified by "direction"
    }

The problem is that I don't know how to tell the codeDOM compiler that it can find the function 'Move' in my own, pre-compiled code. I get the following error from the codeDOM compiler:

Error (CS0103): The name 'Move' does not exist in the current context

Is it even possible? I can't seem to find any examples of other people using codeDOM in this way.

Thank you for your help!

Best way to do this is set the ReferencedAssemblies property on your CompilerParameters to be a lib that contains your additional code.

var parameters = CompilerParameters
{
    ReferencedAssemblies = {
    "my.dll",
    // etc
    }
};
