title: Null / Empty value for a struct in .Net 1.x
body: <p>I need use an empty value for an struct. </p>
  
  <p>I don't know which is the best option to do it. I was thinking on use an static readonly field on the struct for it, but I'm not sure if it's the best option to do it or not. Maybe a  method on a common class, that returns the empty, is a better option. </p>
  
  <p>I'm using the struct for performance reasons, so change it to a class is not an option. And I don't sure if I use the static field, the size of each struct instance will be increased.</p>
  
  <p>Any ideas?</p>
