Adding to list repopulates with the last element

Question

I\'m creating a list of objects called MyComposedModel.

List TheListOfModel = new List();
MyComposedModel ThisObjec         


        

Answer 1

It looks like you're incorrectly re-using a reference to the same object over and over.

When you do this:

MyComposedModel ThisObject = new MyComposedModel();

That create a single reference to a new object and places it on the stack. When you iterate your list and do this:

ThisObject.Reset(); //clears all properties

It's still pointing to the SAME reference, you need to just create a new object of type "MyComposedModel", set it's properties and add it to the list.

Answer 2

You have only 1 object...

MyComposedModel is a reference type. You are filling a list with references to the same single object, and only the last properties stand.

What you probably need:

foreach (MyComposedModel otherObject in some list)
{
 //ThisObject.Reset();                  // clears all properties
   thisObject = new MyComposedModel();  // create a new instance instead
  ....
  TheListOfModel.Add(thisObject);
}
