Question

Say if I have a collection of objects called MyObjects.

Now I am looping on the above collection and adding it to another object called MyObject2. MyObjects has a property called ‘files’.

I want to manipulate the value of files property when I am looping around my first collection. first of all can I do as code shown below. If yes, I get an error as follow :

{Cannot evaluate expression because the current thread is in a stack overflow state.} 

List<objects> MyObjects = Populate(); 
List<objects> MyObject2 = new List<objects>();
foreach(var item in MyObjects)
{
   item.files = "test file" + item.files;
   MyObject2.add(item);
}

edit ::

files property:

 [Transient]
        protected string _files;
        public string files
        {
            get
            {
               return _files;
            }
            set
            {
                _files= value;
            }
        }

Psychic debugging – I suspect your files property looks something like this:

public string files
{
    get { return files; }
    set { files = value; }
}

That will just recurse forever until the stack blows up. That’s just guesswork though, as you haven’t shown us the crucial piece of code.
