C# How to perform macro substitution

Hi..
I have a customer object with properties like this

CUSTOMER.NAME
CUSTOMER.ADDRESS

How can I pass a NAME or ADDRESS to the object (CUSTOMER) and SET the value of NAME and Address

Pass in  and set
NAME
Value = 'BOB'

// Something like this?

var n = "NAME"
var val = 'BOB'

CUSTOMER[N] = val;
