C# - Structures. In C#, a structure is a value type data type. It helps you to make a single variable hold related data of various data types.
The struct keyword is used for creating a structure. Structures are used to represent a record. Suppose you want to keep track of your books in a library. You might want to track the following attributes about each book: Title. Author. Subject. Book IDDefining a Structure. To define a structure, you must use the struct statement. The struct statement defines a new data type, with more than one member for your program.
For example, here is the way you can declare the Book structure. Structures in C# are quite different from that in traditional C or C++. The C# structures have the following features: 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. Class versus Structure. Classes and Structures have the following basic differences: classes are reference types and structs are value typesstructures do not support inheritancestructures cannot have default constructor. In the light of the above discussions, let us rewrite the previous example.
C Programming/Structure and style. You can then go into detail over how each aspect of the program is achieved later on in. C Pointers Fundamentals Explained with Examples. C Program Control Structure : Explain If else with. Then you need to use this conditional structure. Let's check out with C Program to Demonstrate If. A struct in the C programming language. Like its C counterpart, the struct data type in C# (Structure in Visual Basic.NET) is similar to a class.
