Change value inside an (void) extension method

Question

So I have this mock extension method which change a value to another value:

public static void ChangeValue(this int value, int valueToChange)
{
    value = value         


        

Answer 1

I know it's too late, but just for the record, I recently really wanted to do this, I mean...

someVariable.ChangeValue(10);

...apparently looks way neat than the following (which is also perfectly fine)

ChangeValue(ref someVariable, 10);

And I managed to achieve something similar by doing:

public class MyClass
{
    public int ID { get; set; }
    public int Name { get; set; }
}

public static void UpdateStuff(this MyClass target, int id, string name)
{
    target.ID = id;
    target.Name = name;
}

static void Main(string[] args)
{
    var someObj = new MyClass();    

    someObj.UpdateStuff(301, "RandomUser002");
}

Note that if the argument passed is of reference type, it needs to be instantiated first (but not inside the extension method). Otherwise, Leri's solution should work.
