Using clonning of object

// Implement ICloneable to clone the object
public class ControlViewModel : ICloneable
{ 
  public string FieldType { get; set; } 
  public string FieldName { get; set; } 
  public object Clone()
    {
        return this.MemberwiseClone();
    }
}

ControlViewModel cvm = new ControlViewModel(); 
cvm.FieldType ="TEXT"; 
cvm.FieldName ="TEXT1";

// Copy object    
ControlViewModel cvm2 = (ControlViewModel)cvm.Clone() ;
cvm2.FieldName ="TEXT2";

MemberwiseClone() Creates a shallow copy of the current System.Object. ref https://msdn.microsoft.com/en-us/library/system.object.memberwiseclone(v=vs.110).aspx
