How can I load a reference to an int into an int array? (c#)

I just want to fill an array of integers with references to the original variables, so that any changes I make are also reflected in the original variables. In the example below I am copying the value of myInt into the array:

 int[] myArray;
 
 //this line copies the value of myInt instead of a reference:
 myArray[0] = GetComponent<myScript>().myInt;

In order to get a reference instead I am assuming I should use the ref keyword somewhere? I couldn't find any examples of this..

Thanks in advance for any help!
