Questions and Answers

What is the primary purpose of using object initializers in C#?

  • To replace the 'new' keyword in object creation
  • To directly set object properties during instantiation (correct)
  • To eliminate the need for constructors in classes
  • To reduce the number of properties in an object
  • Which of the following describes a benefit of using object initializers in C#?

  • Creating objects with the same starting values for all properties
  • Enabling the creation of multiple objects with different initial assignments (correct)
  • Limiting the number of accessible members in an object
  • Forcing the use of specific constructors with predefined values
  • How does using object initializers in C# help streamline object creation?

  • By automatically initializing all properties to null values
  • By providing a way to create objects with identical initial property values
  • By allowing for setting different initial values for properties without defining multiple constructors (correct)
  • By requiring the explicit definition of default constructors
  • In C#, what does an object initializer allow you to do?
