Static constructors in C# are used to initialize static data members of a class or perform some specific tasks that need to be executed only once before the class is used for the first time. Here are some key points about static constructors:
Static constructors are called automatically before the first instance of the class is created or any static members are referenced.
They have no access modifiers and always have the name .cctor (short for class constructor).
Static constructors cannot take any parameters and have no return type.
They are typically used to initialize static fields or perform one-time setup tasks for the class.
If a static constructor throws an exception, it is not caught by the calling code, and the runtime will terminate the application.
Static constructors are thread-safe, ensuring that static initialization is performed only once, even in a multi-threaded environment.
Static constructors are not inherited by derived classes, and each class has its own static constructor.
Use Cases for Static Constructors
Initializing static fields: Static constructors are commonly used to initialize static fields with complex or conditional values.
Performing one-time setup tasks: They can be used to perform one-time setup tasks, such as loading configuration settings, establishing database connections, or regis...
