Hi, this can not be done.
new A()is an object, it could have a name.objectAis not an object, it is a variable, it holds a reference to the class A object. There could be many more references to the same object, it suffices to doA* objectB=objectA;, now how would the class A object have to know the name of all the variables pointing to it, and in particular the one you want?? Suggestion: give your objects a name by providing a Name property and/or a name argument in their constructor, sonew A("aha");would create a new class A object and give it the name "aha". Now you can ask that object for its name, and/or you can override its ToString() method so it identifies itself. Remark: this works independently of the variable(s) that may refer to that object! :)Luc Pattyn [Forum Guidelines] [My Articles]
