How would I test the sqlparameter in the following to see if it's nothing?

Sub myFunc(ByRef param As SqlParameter)

   If IsNothing(param)= True Then
      Return True
   Else
      Return False
   End IF
EndSub

I've tried various methods to test if "param" is anything but I keep 
getting an error saying "input string not in correct format" on the 
IsNothing(param).  
Thanks...

Use Convert.IsDBNull()
