在通用Windows应用程序（c＃）中复制对象

Question

In want to add a copy of an object to a List in a universal Windows Application. I tried several ways and found IClonable,BinaryFormatter,IFormatter which are all not available in WinRT applications. Please advice me a suitable way to copy a object to a new object. Find my code below.

foreach (var ctrls in _listctrldata)
{
    for (int index = 0; index < ctrls.Controls.Control.Count; )
     {
        listofcontrolvalues.Add(ctrls.Controls.Control[index]);
        index++;
     }

   SetControlvalues(null, _vcontainer, listofcontrolvalues);

 //_vcontainer changes everytime the loop rotates and Should create a copy of  _vcontainer here//  

  VerticalContainer vcont = new VerticalContainer ();
  vcont = _vcontainer;

 _listcontrols.Add(vcont);

}

Answer 1

I don't know what the class VerticalContainer is.

If it is a .NET class defined by you self, you can just defined a clone method to create a new object and copy all of the build-in data type fields. If it is a Windows Runtime class, I'm afraid you cannot easily copy it because there are some internal and private data members you cannot access.

In your code. VerticalContainer vcont = new VerticalContainer (); vcont = _vcontainer;

You only changed the vcont reference from new created object to the old _vcontainer, this will not work, you need to copy all of fields from _vcontainer to vcont one by one.
