Is it possible to refactor this extension method?

Question

I have the following extension method:

public static void ThrowIfArgumentIsNull(this T value, string argument) 
    where T : class
{
    if (value          


        

Answer 1

I would recommend that you rather do the following:

public static void ThrowIfArgumentIsNull(this object value, string argument) 
{
    if (value == null)
    {
        throw new ArgumentNullException(argument);
    }
}

Using generics in this case doesn't seem to add any value. But as to your original question, I don't think that's possible.
