c# - How to create a reference to a value-field

Is there a way in C# to create a field which is a reference to another field which is a value type?

class myClass
{
    bool b1;

    public void method1(ref bool b)
    {
        b1 = b;
    }
}

I want b1 to reference the value of b, just as b references the value of the original argument, so that changes to b1 will affect the original argument.

EDIT:

What I’m trying to achieve is a myCheckBox class which automatically updates a field. See: How do I change a value argument from within an event handler?

Sure! Take a look at Eric's answer to this question:

Setting a ref to a member field in C#

As others have pointed out, you cannot store a reference to a variable in a field in C#, or indeed, any CLR language.

Of course you can capture a reference to a class instance that contains a variable easily enough
