Structs in .NET - ablealias/asp.net GitHub Wiki

The struct type is suitable for representing lightweight objects such as Point, Rectangle, and Color. Structures are used to represent a record. It is an error to define a default (parameterless) constructor for a struct. It is also an error to initialize an instance field in a struct body. You can initialize struct members only by using a parameterized constructor or by accessing the members individually after the struct is declared. Any private or otherwise inaccessible members can be initialized only in a constructor.

Structures can have methods, fields, indexers, properties, operator methods, and events.

Structures can have defined constructors, but not destructors. However, you cannot define a default constructor for a structure. The default constructor is automatically defined and cannot be changed.

  • Unlike classes, structures cannot inherit other structures or classes.

  • Structures cannot be used as a base for other structures or classes.

  • A structure can implement one or more interfaces.

  • Structure members cannot be specified as abstract, virtual, or protected.

  • When you create a struct object using the New operator, it gets created and the appropriate constructor is called. Unlike classes, structs can be instantiated without using the New operator.

  • If the New operator is not used, the fields remain unassigned and the object cannot be used until all the fields are initialized.

  • classes are reference types and structs are value types

  • structures do not support inheritance

  • structures cannot have default constructor
