Deep Copy of a C# Object

Question

I am working on some code that is written in C#. In this app, I have a custom collection defined as follows:

public class ResultList : IEnumerable&l         


        

Answer 1

One of the reasons why your ResultList class won't work with Jon Skeet's example is because it does not implement the ICloneable interface.

Implement ICloneable on all the classes that you need cloned, e.g.

public class ResultItem : ICloneable
{
  public object Clone()
  {
    var item = new ResultItem
                 {
                   ID = ID,
                   Name = Name,
                   isLegit = isLegit
                 };
    return item;
  }
}

And also on ResultList:

public class ResultList : IEnumerable, ICloneable where T : ICloneable
{
  public List Results { get; set; }
  public decimal CenterLatitude { get; set; }
  public decimal CenterLongitude { get; set; }

  public object Clone()
  {
    var list = new ResultList
                 {
                   CenterLatitude = CenterLatitude,
                   CenterLongitude = CenterLongitude,
                   Results = Results.Select(x => x.Clone()).Cast().ToList()
                 };
    return list;
  }
}

Then to make a deep copy of your object:

resultList.clone();
