Calling a c# function with a ref parameter to a struct

Question

public struct TestStruct
public bool Value;
public class Functions
void Flip(ref TestStruct testStruct)
testStruct.Value = !testStruct.Value;
I'm trying to call the from c++ like this
TestStruct ^ testStruct = gcnew TestStruct();
Functions ^ functions = gcnew Functions();
functions->Flip(testStruct);
This gives an compiler error saying "cannot convert parameter 1 from 'TestStruct ^' to 'TestStruct %'
I know that this is the correct syntax if TestStruct was a class and not a struct. But i'm using a third party library so changing from struct to class is not an options.
Anybody know how to make this call. 
Found the answer:
functions->Flip(*testStruct);

Hi Grarup,
I took a stab at getting this to run and compile and this is what I came up with.  Let me know if this helps at all.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApplication1
class Program
static void Main(string[] args)
Console.WriteLine("\"True\" or \"False\"?");
bool boolVal = bool.Parse(Console.ReadLine());
Functions f = new Functions();
TestStruct t = new TestStruct() { Value = boolVal };
f.Flip(ref t);
Console.WriteLine(string.Format("Flipped value = {0}: ", t.Value));
Console.ReadLine();
public struct TestStruct
public bool Value;
public class Functions
public void Flip(ref TestStruct testStruct)
testStruct.Value = !testStruct.Value;
Best of luck.
