C# CodeDom: Custom class as parameter in string code

Question

Sorry I'm new at programming using CodeDom, I have this problem that I couldn't solve. Was thinking if some of you folks know the solution.

I have the following code inside a class file:

public class AnotherCustomClass {
    public string Employer { get; set; }
    public DateTime? DateOfHire { get; set; }
}

public class CustomClass {
    public int X { get; set; }
    public int Y { get; set; }
    public AnotherCustomClass[] YetAnother { get; set; }
}

public void DoSomething()
{
    string expression = @"using System;  
    namespace MyNamespace {
        public class MyClass {
            public static int DoStuff(CustomClass myCustomClass) {
                return myCustomClass.X + myCustomClass.Y;
            }
        }
    }";

    CSharpCodeProvider provider = new CSharpCodeProvider();
    CompilerParameters assemblies = new CompilerParameters(new[] { "System.Core.dll" });
    CompilerResults results = provider.CompileAssemblyFromSource(assemblies, expression);
    Type temporaryClass = results.CompiledAssembly.GetType("MyNamespace.MyClass");
    MethodInfo temporaryFunction = temporaryClass.GetMethod("DoStuff");
    CustomClass data = new CustomClass() { X = 1, Y = 2 };
    object result = temporaryFunction.Invoke(null, new object[] { data });
    return result;
}

I would like to input the data (a custom created class, that has an array of another custom class inside) variable as the parameter in the DoStuff function, I keep on having errors. Is there a way to solve this issue?

Multiple errors, change this way:

string expression = @"using System;  
namespace MyNamespace {
    public class MyClass {
        public static int DoStuff(CustomClass myCustomClass) {
            return myCustomClass.X + myCustomClass.Y;
        }
    }

    public class CustomClass
    {
        public int X;
        public int Y;
        public CustomClass(int x, int y) { X = x; Y = y; }
    }
}";

CSharpCodeProvider provider = new CSharpCodeProvider();
CompilerParameters assemblies = new CompilerParameters(new string[] { "System.dll" });
CompilerResults results = provider.CompileAssemblyFromSource(assemblies, expression);
Type temporaryClass = results.CompiledAssembly.GetType("MyNamespace.MyClass");
Type parClass = results.CompiledAssembly.GetType("MyNamespace.CustomClass");
MethodInfo temporaryFunction = temporaryClass.GetMethod("DoStuff");
object mc = parClass.GetConstructor(new Type[] { typeof(int), typeof(int) }).Invoke(new object[]{1,2});
object result = temporaryFunction.Invoke(null, new object[] { mc });
