How to execute C # code at runtime in Xamarin Android?

I have an Android app in Xamarin Studio. I want to execute the code put in text (string). For example this question will help me in a Visual Studio Windows application. But I cannot use this answer in Xamarin Android. This is my example in a C # Windows application:

public class CodeLuncher
{
    public static void LunchCSCode(string site, string typeName, string methosName)
    {
        try
        {
            var provider = CSharpCodeProvider.CreateProvider("c#");
            var options = new CompilerParameters();
            string text = new System.Net.WebClient().DownloadString(site);

            foreach (var item in GetRefrences(text))
            {
                options.ReferencedAssemblies.Add(item);
            }
            string code = GetCode(text);
            var results = provider.CompileAssemblyFromSource(options, new[] { code });
            if (results.Errors.Count > 0)
            {
                foreach (var error in results.Errors)
                {
                    Console.WriteLine(error);
                }
            }
            else
            {
                var t = results.CompiledAssembly.GetType(typeName);
                t.GetMethod(methosName).Invoke(null, null);
            }
        }
        catch
        {

        }
    }


    static string[] GetRefrences(string text)
    {
        Regex regExp = new Regex("<Refrences>(.*?)</Refrences>", RegexOptions.Multiline | RegexOptions.IgnorePatternWhitespace | RegexOptions.Singleline);
        string str = regExp.Match(text).Groups[1].Value;
        List<string> retText = new List<string>();
        foreach (var item in str.Trim().Split(new string[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries))
        {
            retText.Add(item);
        }
        return retText.ToArray();
    }

    static string GetCode(string text)
    {
        Regex regExp = new Regex("<CSharpCode>(.*?)</CSharpCode>", RegexOptions.Multiline | RegexOptions.IgnorePatternWhitespace | RegexOptions.Singleline);
        string str = regExp.Match(text).Groups[1].Value;
        return str.Trim();
    }
}
