C# extension method for fast object cloning.

Nuget

This is a speed-optimized fork of Alexey Burtsev's deep copier. Depending on your usecase, this will be 2x - 3x faster than the original. It also fixes some bugs which are present in the original code. Compared to the classic binary serialization/deserialization deep clone technique, this version is about seven times faster (the more arrays your objects contain, the bigger the speedup factor).

The speedup is achieved via the following techniques:

  • object reflection results are cached
  • don't deep copy primitives or immutable structs & classes (e.g. enum and string)
  • to improve locality of reference, process the 'fast' dimensions or multidimensional arrays in the inner loops
  • use a compiled lamba expression to call MemberwiseClone

How to use:

Use NuGet package manager to add the package Baksteen.Extensions.DeepCopy to your project. Then:

using Baksteen.Extensions.DeepCopy;
...
var myobject = new SomeClass();
...
var myclone = myobject.DeepCopy()!;    // creates a new deep copy of the original object

Note: the exclamation mark (null-forgiving operator) is only required if you enabled nullable reference types in your project
