How to use ref variable outside calling method in c#

Question

How can I use ref variable outside the calling method in C#.

I will explain what I would like to acheive.

I have a method inside a class(MyClass), which looks like

private MyObject myobj;
public ref MyObject GetMyObject()
{
    return ref myobj;
}

Now I am fetching the variable inside another method from different class(FetchClass)

private MyObject fetchObj;
void Start()
{
    fetchObj = ref MyClass.instance.GetMyObject(); //getting error here
}

I like to use fetchObj in different method in the same class. Thats the reason I have declared outside. But I am getting error in Start method.

Since your MyObject is a class you can use an expression bodied read-only property:

private MyObject fetchObj => MyClass.instance.GetMyObjectNotByRef();
