Re: C# Nullable types

Tech-Archive recommends: Fix windows errors by optimizing your registry

If it's a member variable, it's assigned the null value at runtime. It's not unassigned.

But in this case, you always pass an assigned value to the method. It cannot be unassigned by definition. Its either null or has reference to something.

It can be unassigned, if it is a member and not a local variable.

The bottom line (the one that matters, in other words) is that the ideas I expressed in my original reply were correct, but the words I used to express them were parsed incorrectly by people for whom the reply was not intended, for wahtever reason. The OP has not asked for clarification regarding the reply. I can only hope that this is because the OP understood what I was saying.

In the end, it doesn't matter which end of the boiled egg one begins at, as long as one eats the egg.

Hi Jon,

Well, it's a bit more complicated than that. If it's a parameter, for example, the compiler doesn't complain at all. Example:

public boo StringIsNull(string s)
{
return (s == null);
}


But in this case, you always pass an assigned value to the method. It cannot be unassigned by definition. Its either null or has reference to something.

This differs from local variables.

Best regards,
Henning Krause
