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

See also ArgumentNullException and refactoring for a complete solutions along the same lines as the answer.

What about:

public void Save(Category qwerty)
{   
   ThrowIfArgumentIsNull( () => return qwerty );
   qwerty.ThrowIfArgumentIsNull("qwerty");    
   // ....
}

then define ThrowIfArgumentIsNull as

public static void ThrowIfArgumentIsNull(Expression> test)
{
   if (test.Compile()() == null)
   {
      // take the expression apart to find the name of the argument
   }
}

sorry I don't have the time to fill in the detail or provide the full code at present.
