Add variable to object reference
-
Dear all, If I create a new reference to an object, I would like to add a variable to that newly create reference. Let's say :
Foo foo = new Foo();Now, everythime the code runs, I would like a variable added tofoo, let's say : First time it is called :Foo foo1 = new Foo();Second :Foo foo2 = new Foo();Is there an easy way of doing this ? Cheers, -

Cheers,Hi , I too wonder of the exact situation you would require to do that.If you can tell that we should be able to help you ourt more. However calling the new on any object will be creating a new instance itself eg: Foo f; for(int i=0;i<10;i++) { f= new Foo(); } will create 10 new instances rather than 1 even though you are using the same variable name. laddie

Sounds like you need an array or list
List fooList = new List();
fooList.Add(new Foo());

newwould create a new instance ( hence the name ). I can understand why this could be confusing. I will try to explain as good as I can why I would want this. I create a new array of points, which I add to a ObjectList.private void dataGridView_CellContentClick(object sender, DataGridViewCellEventArgs e) { foreach (DataGridViewRow SelectedRow in dataGridView.SelectedRows) { Points pt = new Points(); pt.AddPoint(X,Y); RenderableObjects.Objects.Add(pt); } }When I rerender the form, the points (X,Y) show on the screen. So everytime I click on a row in the datagridview, the method is called. However, everytime a new instance ofPoints()is added to the RenderableObjectslist. But before adding the new X and Y point , I want the list to be cleared. This can be achieved by :RenderableObjects.Objects.Remove(pt);However you can't use this line in the same method, since a new reference is initiated and therefore the previousptis not removed. My though was ( and it was just a though ) : If I could add a variable to the new reference, I could specifically filter, something like := new Points(); pt[x].AddPoint(X,Y); RenderableObjects.Objects.Add(pt[x]); int y = x -1 ; RenderableObjects.Objects.Remove(pt[y]); x++; } }For obvious reasons , this code would not run 'cause you cannot use an array (x) size on a variable declaration. Like I said, it was just a thought. I hope I was able to clearify it a bit more. Cheers
