What "new" means

Ive been thinking about what the real meaning of "new" in c#
the basic meaning that i have is when you use the new command it means a new location at the memory, like this example

Mobile a = new Mobile();
Mobile b = a;
b.Name = "foo";

this means, that i will create a new mobile a then set another reference to mobile a, wich will be called b, so when i set b.Name = "foo" it will also modify the Name in a, right?

so what i want, is to create 2 identical Mobiles, but with different names

Mobile a = new Mobile();
Mobile b = new Mobile();
b = a;
b.Name = "foo";

this will not work, because when you set b = a it will also reference the memory pointer from a to b

so, how i create 2 identical mobiles but with different names, not one Mobile with two references?
Will i have to copy each attribute like Name, Str..one by one ?

Yes, for RunUO you will need to copy each Property... however, there is a interesting concept in programming called Shallow Cloning and Deep Cloning. You can use these in C#, but you would have to implement them. It's not really something I have time to go into detail about, but here are some links explaining it.

that was the explanation that i needed
