use extension function to change variable value

November 20, 2022

Is there a way to use an extension method to change a variable to the return value?

I have a basic remap function

public static float Remap(this float value, float min1, float max1, float min2, float max2)
        => (value - min1) / (max1 - min1) * (max2 - min2) + min2;

distance.Remap(0, 2, 120, 80);

I want distance to have the value of the return without explicitly setting it like

distance = distance.Remap(0, 2, 120, 80);

>Solution :

ref Should do this just fine.

By making the this float value a ref parameter,
You can alter the input by setting it as your return value.

 public static float Remap(this ref float value, float min1, float max1, float min2, float max2)
    => value = (value - min1) / (max1 - min1) * (max2 - min2) + min2;
