Reference types

If i make a reference to a refence type then if i make another reference to the same object and change it, the inicial one will be changed as they point to the same object right? if i have 2 or more hashtables that point to the same object, they are not creating new objects but just making references to the other object right?

Huh?

If you mean something like this, it works:

Code:

---

System.Collections.Hashtable table1 = new System.Collections.Hashtable();
System.Collections.Hashtable table2 = table1;
table1.Add("keyString", "dataString");
System.Console.Println(table2["keyString"]);

---

myClass mClass = new myClass();

Hashtable h1 = new hashtable();
hashtable h2 = new hashtable();

h1.add("class", mClass);
h2.add("class", mClass);

//now i make something like:
h1["class"].SOmething = 5;

//will now h2["class"].something be 5 too?

Yes, because you are storing a pointer (reference) to the object in the hashtable.
