[Solved] why delegate work as ref? [closed]

by


You can change the method like that:

public class Util
{
    public static T[] Transform<T>(T[] values, Transformer<T> t)
    {
        return values.Select(x => t(x)).ToArray();
    }
}

Then you can call it like

var result = Utils.Transform(values, Square);

If you can’t change that method, then you need to copy the array before calling:

var result = values.ToArray();
Utils.Transform(result, Square);
