C++

//.CPP file 
#include "stdafx.h"
using namespace System;
using namespace System::Collections::Generic;
namespace XNameSpace{

	UserId ClassName::GetId() // 'GetId' is not a member of ClassName
	{
		String^ strUserName = "sdfasd";
		String^ strPasscode = "sdfa";
		UserId ^ObjRole= AuthenticationManager::NewKTRole();

		Dictionary<String^, Object^>^ users= gcnew Dictionary<String^, Object^>();

		users->Add("UserName", strUserName);
		usersusers->Add("Passcode", strPasscode);

		UserId Id = (UserId)ObjRole->GetId(users);

		return Id;
	};
}

//.H FILE

C++

#include "stdafx.h"

namespace XNameSpace{
	
	class ClassName
	{
	public:
		UserId GetId(); // Error 'GetId' Unknown override specifier // syntax error : '(' , unexpected token preceding ;
	};

	enum UserId
	{
		KTUniversal = -1,

		None,
		//
		C4,
		//
		C5,
		//
		C1,
		//
		C2,
		//
		C3,
	};

What I have tried:

I am getting errors
1) 'GetId' Unknown override specifier
2) syntax error : '('
3) unexpected token preceding ;
4) 'GetId' is not a member of ClassName
Usually we keep declaration in header and its implementation in CPP file.

Could anyone help on this topic?

Your UserId is an enum, and you are expecting to call a function on it. Any reason for that?

Move the enum definition above the class definition in the header file or add a forward declaration:

namespace XNameSpace{

    // Forward declaration for UserId enum
    enum UserId;

    // Can now use the UserId enum here
    class ClassName
    {
    public:
        UserId GetId();
    };
    
    // enum definition
    enum UserId
    {
        KTUniversal = -1,
        // ...
    };
    // ...
}

Your enum is treated like a class: It must be declared before first used. The only exception is when it is part (member) of a class. Then it might be defined after being used by other members:

C++

class ClassName
{
public:
    // Can use ClassNameUserId here because it is a class member
    ClassNameUserId GetId();

    enum ClassNameUserId
    {
        KTUniversal = -1,
    };
};
