Assign a reference of an integer in a class

Question

Is it possible to pass an integer as reference at class initialization and safe the reference?

class Foo {
    private int _refVal;
    public Foo(ref int val) {
        _refval = val; // saves the value, not the reference
    }
}

I could use pointers, but then I need an unsafe context.

Answer 1

This is not possible.

Instead, you can use a class with a writable property, like this:

class Reference<T> {
    public T Value { get; set; }
    public Reference(T value) { Value = value; }
}
