c# - Create class for integer value identifier and new Number

I'm trying to pass some training tests with C#, but I've really stuck with this one

The task says: fix compiler error without changing of any string inside the Function(), create integer class to identify integer variable with specific name myIntIdentifier and output myNmb value

        public void Function()
        {                
             myIntIdentClass orgNumb = new Number { numbVal = 1, numbStr = "One"};
             int myNmb= orgNumb;

             Console.WriteLine(myNmb);
        }

Here is what I have tried:

    public class myIntIdentClass
    {
        public int numb { get; set; }

        public static implicit operator int(myIntIdentClass v)
        {
            throw new NotImplementedException();
        }
    }

    public class Number
    {
        private int intVal { get; set; }
        private string strVal { get; set; }
    }

but the new Number shows:

'Number' is inaccessible due to its protection level

You cannot initialize the class props because they are private.

here you are trying to init your class using one line initializer but your props are private, so you cannot access them.

 new Number { numbVal = 1, numbStr = "One"};

you can set the encapsulation level of the props in the Number class to public to fix this error.

   public class Number
    {
        public int intVal { get; set; }
        public string strVal { get; set; }
    }

By the way the convention for props is encapsulation level as public and naming in PascalCase.

And another error is that you are missing an implicit casting from Number to myIntIdentClass
