对于堆中的值，是否只需要一个引用？

Question

示例1

class Program
{
    static void Main()
    {
        TEST();
    }

    static void TEST()
    {
        string stringTest = "somestring"; //this value stored in heap part of the memory becase its a object type not a primitive type.
        
        int first = 5;    //this one stroed in stack part because its a primitive type.
        int second = first;  //but this one includes a reference, so this will be stored in heap part ???
    }
}

示例2

class testObject
{
  
}
class Program
{
    static void Main()
    {
        var first = new testObject();  // newly created testObject stored in heap because it's a class which is an object and includes a reference, and "first" value stored in stack because it is just a reference.

        new testObject();// but this one doesnt include a reference so is this still stored in the heap?
    }
}

那么，对于堆中的一个值，只需要一个引用？还是按照对象的类型出现的每一个对象也都分配到了堆上？

嗯，我做了一些更多的研究，据我了解，当您创建一个新对象时，即使该对象不包含引用，它也会被放入堆中。我认为 YouTube 视频和一些在线课程中的解释不正确:-D
