D/W array is a dynamic array in .Net that can grow or shrink in size. ArrayList is a collection class that can store objects of any type.

• D/W array is a resizable array that automatically adjusts its size as elements are added or removed.

• ArrayList is a collection class that can store objects of any type, allowing for flexibility in data storage.

• Example: D/W array - string[] myArray = new string[5]; ArrayList - ArrayList

readonly variables can be assigned a value either at the time of declaration or in the constructor, while const variables must be assigned a value at the time of declaration and cannot be changed.

• readonly variables can be assigned a value at runtime, while const variables must be assigned a value at compile time

• readonly variables can be assigned a value in the constructor, while const variables cannot

const is compile-time constant, while readonly is runtime constant.

• const values are determined at compile time and cannot be changed during runtime

• readonly values can be assigned a value either at the declaration or in the constructor and can be changed at runtime

• const is used for values that are known at compile time, like mathematical constants

• readonly is used when the value needs to be initialized at runtime, like d

Dependency injection is a design pattern where components are given their dependencies rather than creating them internally.

• Dependency injection helps in achieving loose coupling between classes.

• It allows for easier testing and maintenance of code.

• There are three types of dependency injection - constructor injection, setter injection, and interface injection.

• Example: Instead of creating an instance of a class within an...read more

Injecting dependencies allows for better flexibility, testability, and maintainability in code.

• Injecting dependencies means passing objects that a class needs rather than creating them within the class.

• This allows for easier testing by mocking dependencies and swapping them out for different implementations.

• Dependency injection frameworks like Unity, Ninject, or Autofac can help manage dependencies.

• Example: Instead of ...read more
