在这种情况下，对于浅拷贝，使用强制转换可能会有所帮助:

IList CloneList(IList list)
{
    IList result;
    result = (IList)Activator.CreateInstance(list.GetType());
    foreach (object item in list) result.Add(item);
    return result;
}

适用于通用列表:

List<T> Clone<T>(List<T> argument) => (List<T>)CloneList(argument);

public static Object CloneType(Object objtype)
{
    Object lstfinal = new Object();

    using (MemoryStream memStream = new MemoryStream())
    {
        BinaryFormatter binaryFormatter = new BinaryFormatter(null, new StreamingContext(StreamingContextStates.Clone));
        binaryFormatter.Serialize(memStream, objtype); memStream.Seek(0, SeekOrigin.Begin);
        lstfinal = binaryFormatter.Deserialize(memStream);
    }

    return lstfinal;
}

我已经为我自己做了一些扩展，它转换了ICollection的项目，没有实现IClonable

static class CollectionExtensions
{
    public static ICollection<T> Clone<T>(this ICollection<T> listToClone)
    {
        var array = new T[listToClone.Count];
        listToClone.CopyTo(array,0);
        return array.ToList();
    }
}

如果你需要一个具有相同容量的克隆列表，你可以尝试这样做:

public static List<T> Clone<T>(this List<T> oldList)
{
    var newList = new List<T>(oldList.Capacity);
    newList.AddRange(oldList);
    return newList;
}

public class CloneableList<T> : List<T>, ICloneable where T : ICloneable
{
  public object Clone()
  {
    var clone = new List<T>();
    ForEach(item => clone.Add((T)item.Clone()));
    return clone;
  }
}

使用AutoMapper(或任何您喜欢的映射库)来克隆是简单的，而且易于维护。

定义映射:

Mapper.CreateMap<YourType, YourType>();

施展魔法吧:

YourTypeList.ConvertAll(Mapper.Map<YourType, YourType>);
