C#, unlike Java, allows the use of lambda functions as a way to define special data structures called expression trees. Whether they are seen as an executable function or as a data structure depends on compiler type inference and what type of variable or parameter they are assigned or cast to.
In some object-oriented programming languages such as C# and Java, reflection can be used to bypass member accessibility rules. For C#-properties this can be achieved by writing directly onto the (usually invisible) backing field of a non-public property. It is also possible to find non-public methods of classes and types and manually invoke them.
