What is the purpose of “required” in C#?

In C#, “required” is a common keyword used to indicate that a certain property or field must be provided when instantiating an object. When a property or field is marked as “required,” it means that the value for that property or field must be provided when creating the object, otherwise it will result in a compilation error or a runtime error. This helps ensure the correctness and completeness of the program, avoiding potential errors.
