 Loading resources from code is easy. There are two ways to do it. The
 first is to use load(), like this:
 
-::
+.. tabs::
+ .. code-tab:: gdscript GDScript
 
     func _ready():
             var res = load("res://robi.png") # resource is loaded when line is executed
             get_node("sprite").texture = res
 
+ .. code-tab:: csharp
+
+    public override void _Ready()
+    {
+        var texture = (Texture)GD.Load("res://robi.png"); // resource is loaded when line is executed
+        var sprite = (Sprite)GetNode("sprite");
+        sprite.Texture = texture;
+    }
+
 The second way is more optimal, but only works with a string constant
 parameter, because it loads the resource at compile-time.

+.. tabs::
+ .. code-tab:: gdscript GDScript
 
     func _ready():
             var res = preload("res://robi.png") # resource is loaded at compile time
             get_node("sprite").texture = res
 
+ .. code-tab:: csharp
+
+    // preload() is unavailable in C Sharp

 Loading scenes

 Scenes are also resources, but there is a catch. Scenes saved to disk

 This method creates the nodes in the scene's hierarchy, configures 
 them (sets all the properties) and returns the root node of the scene, 
 which can be added to any other node.
