+
+C# collections
+==============
+
+The .NET base class library contains multiple collection types that can be
+used to store and manipulate data. Godot also provide some collection types
+that are tightly integrated with the rest of the engine.
+
+Choose a collection
+-------------------
+
+The main difference between the `.NET collections <https://learn.microsoft.com/en-us/dotnet/standard/collections/>`_
+and the Godot collections is that the .NET collections are implemented in C# while
+the Godot collections are implemented in C++ and the Godot C# API is a wrapper over it,
+this is an important distinction since it means every operation on a Godot collection
+requires marshaling which can be expensive especially inside a loop.
+
+Due to the performance implications, using Godot collections is only recommended
+when absolutely necessary (such as interacting with the Godot API). Godot only
+understands its own collection types, so it's required to use them when talking
+to the engine.
+
+If you have a collection of elements that don't need to be passed to a Godot API,
+using a .NET collection would be more performant.
+
+.. tip::
+
+    It's also possible to convert between .NET collections and Godot collections.
+    The Godot collections contain constructors from generic .NET collection interfaces
+    that copy their elements, and the Godot collections can be used with the
+    `LINQ <https://learn.microsoft.com/en-us/dotnet/standard/linq>`_
+    ``ToList``, ``ToArray`` and ``ToDictionary`` methods. But keep in mind this conversion
+    requires marshaling every element in the collection and copies it to a new collection
+    so it can be expensive.
+
+Despite this, the Godot collections are optimized to try and avoid unnecessary
+marshaling, so methods like ``Sort`` or ``Reverse`` are implemented with a single
+interop call and don't need to marshal every element. Keep an eye out for generic APIs
+that take collection interfaces like `LINQ <https://learn.microsoft.com/en-us/dotnet/standard/linq>`_
+because every method requires iterating the collection and, therefore, marshaling
+every element. Prefer using the instance methods of the Godot collections when possible.
+
+To choose which collection type to use for each situation, consider the following questions:
+
+* Does your collection need to interact with the Godot engine?
+  (e.g.: the type of an exported property, calling a Godot method).
+
+   * If yes, since Godot only supports :ref:`Variant-compatible <doc_c_sharp_variant>`
+     types, use a Godot collection.
+   * If not, consider `choosing an appropriate .NET collection <https://learn.microsoft.com/en-us/dotnet/standard/collections/selecting-a-collection-class>`_.
+
+* Do you need a Godot collection that represents a list or sequential set of data?
+
+   * Godot :ref:`arrays <doc_c_sharp_collections_array>` are similar to the C# collection ``List<T>``.
+   * Godot :ref:`packed arrays <doc_c_sharp_collections_packedarray>` are more memory-efficient arrays,
+     in C# use one of the supported ``System.Array`` types.
+
+* Do you need a Godot collection that maps a set of keys to a set of values?
+
+   * Godot :ref:`dictionaries <doc_c_sharp_collections_dictionary>` store pairs of keys and values
+     and allow easy access to the values by their associated key.
+
+Godot collections
+-----------------
+
+.. _doc_c_sharp_collections_packedarray:
+
+PackedArray
+^^^^^^^^^^^
+
+Godot packed arrays are implemented as an array of a specific type, allowing it to be
+more tightly packed as each element has the size of the specific type, not ``Variant``.
+
+In C#, packed arrays are replaced by ``System.Array``:
+
+======================  ==============================================================
+GDScript                C#
+======================  ==============================================================
+``PackedInt32Array``    ``int[]``
+``PackedInt64Array``    ``long[]``
+``PackedByteArray``     ``byte[]``
+``PackedFloat32Array``  ``float[]``
+``PackedFloat64Array``  ``double[]``
+``PackedStringArray``   ``string[]``
+``PackedColorArray``    ``Color[]``
+``PackedVector2Array``  ``Vector2[]``
+``PackedVector3Array``  ``Vector3[]``
+======================  ==============================================================
+
+Other C# arrays are not supported by the Godot C# API since a packed array equivalent
+does not exist. See :ref:`Variant <doc_c_sharp_variant>` for a list of all the compatible
+types.
+
+.. _doc_c_sharp_collections_array:
+
+Array
+^^^^^
+
+Godot arrays are implemented as an array of ``Variant`` and can contain several elements
+of any type. In C#, the equivalent type is ``Godot.Collections.Array``.
+
+The generic ``Godot.Collections.Array<T>`` type allows restricting the element type to
+a :ref:`Variant-compatible <doc_c_sharp_variant>` type.
+
+An untyped ``Godot.Collections.Array`` can be converted to a typed array using the
+``Godot.Collections.Array<T>(Godot.Collections.Array)`` constructor.
+
+.. note::
+
+    Despite the name, Godot arrays are more similar to the C# collection
+    ``List<T>`` than ``System.Array``. Their size is not fixed and can grow
+    or shrink as elements are added/removed from the collection.

+Dictionary
+^^^^^^^^^^
+
+Godot dictionaries are implemented as a dictionary with ``Variant`` keys and values.
+In C#, the equivalent type is ``Godot.Collections.Dictionary``.
+
+The generic ``Godot.Collections.Dictionary<TKey, TValue>`` type allows restricting the key
+and value types to a :ref:`Variant-compatible <doc_c_sharp_variant>` type.
+
+An untyped ``Godot.Collections.Dictionary`` can be converted to a typed dictionary using the
+``Godot.Collections.Dictionary<TKey, TValue>(Godot.Collections.Dictionary)`` constructor.
+
+.. tip::
+
+    If you need a dictionary where the key is typed but not the value, use
+    ``Variant`` as the ``TValue`` generic parameter of the typed dictionary.
+
+    .. code-block:: csharp
+
+        // The keys must be string, but the values can be any Variant-compatible type.
+        var dictionary = new Godot.Collections.Dictionary<string, Variant>();
