Not sure what you mean by a null string so just in case, here's two
options:

Null: if (myString == null)
Empty: if (myString == "")

Null string, as in char(0) or a string that is null:

if(stringName == null)
{
// you detected a null string
}

char[] charArray = stringName.ToCharArray();

//Assume only one char if it is a null char
if(charArray[0] == 0)
{
// only a null char
}

I am flying by the seat of my pants here, so you may have to alter the code
to get past debug. The theory is sound, however.
