Cloning Options Based on Depth and .NET Version

Depending on the depth of the desired copy and the version of .NET you're using, several options are available:

Shallow Copy with ToDictionary

For a shallow copy, which does not preserve nested object references, you can utilize the ToDictionary LINQ method in .NET 3.5 and above:

var newDictionary = oldDictionary.ToDictionary(entry => entry.Key, entry => entry.Value);

Deep Copy with ICloneable Implementation

If a deep copy is desired, and your generic type T implements the ICloneable interface, you can use the following code:

var newDictionary = oldDictionary.ToDictionary(entry => entry.Key, entry => (T)entry.Value.Clone());
