Reference to class not working?

Hello, I am running in a problem, I have a class called Test, and I create 10 instances of it. The class contains an integer. public class Test { public Test(int init) { g = init; } public int g; } Now, I set the current "test" instance: Test current = "one of the 10 instances here"; Now.. if I modify the contents of the current instance after setting it as current, the current Test won't reflect these changes. For example: Test current = inst1; inst1.g = 100; now, current.g doesnt contain 100, but the old value.. I am confused. Doesn't reference work that way? Also, how do I use WeakReference, and where is it suitable at? Sorry for so many questions.

Yes, that's the way it works. inst1.g == 100 so current.g == 100. I reproduced your code as you described it and it worked for me the way you expected it to work for you. My messagebox shows "101". The dhange to object i1 was reflected in object current. BTW, it's usually better for real world applications to use a public property to provide access to class members instead of making the members themselves public as in : private int fg; pubilc int g { get { return g; } set { g = value; } } Here is the code that I used. Only the names are slightly different, and I only create ONE instance of the object. Everything else should be as you described it. private void button3_Click(object sender, System.EventArgs e) { Class1 i1 = new Class1(100); Class1 current = i1; i1.g = 101; MessageBox.Show(current.g.ToString()); } public class Class1 { public Class1(int i) { g = i; } public int g; } I don't know about WeakReference...
