How the C++ project to invoke C# object ?

C#

In a common solution, there are 2 projects, one is the c++ project and the other is the c# project.
There is a class in the c# project, as follows:

namespace CSLib
{
Class Person
{
     Private string PersonName = string.Empty;
     
     Public Person (string personName)
     {
          PersonName = personName;
     }
     
     Public string GetPersonName ()
     {
         Return PersonName;
     }
}

Person mPerson = new Person("Jack");
}

So, how c++ engineering calls mPerson.GetPersonName to get Jack

What I have tried:

#using "..\debug\CSLib.dll"
using namespace CSLib;

I only know how to call the class of c# through c++, but not the method of calling his object method
