AN OO Basic

[JEHMayo]

I have a routine that references an item of type Object. The particular item implements the IComparable interface. In my routine, how do I call its CompareTo method? Edited August 19, 2005 by JEHMayo

vb:

CType(yourObject, IComparable).Compare(....)

 

or

c#

((IComparable)yourObject).Compare(...)

 

(c# isn't my strong point, so it might be syntactically out!)

((IComparable)yourObject).Compare(...)

depending on where in your code you are casting, in c# it is best to use the as operator and then test for null:

 

IComparable test = yourObject as IComparable;
if (test != null)
   test.Compare(...);

That's it! A needed reminder for a rusty brain.
