It also comes with improved debugging facilities and a new framework to simplify the use of LINQ.
What Kind of Questions are Asked in IKM Assessment C# 4.5?
Questions asked in IKM Assessment C# 4.5 center around popular topics such as basic syntax, object-oriented programming, generic programming, file IO and LINQ. Questions may also cover features exclusive to C# 4.5, such as async operations, covariance, and optional parameters.
Questions & Answers
This section includes 50 of the top IKM Assessment C# 4.5 Programming questions and answers.
What is the most current version of the C# language?
- The most current version of the C# language is C# 4.5.
What is an object in C#?
- An object in C# is a data structure that contains fields, methods and properties to perform an operation or manipulate data. Objects are created from classes.
What is the difference between a class and an object?
- A class is just a definition or a blueprint of an object. It defines the structure of the object, including fields, methods and properties. An object is an instance of a class.
What is the use of the “using” statement in C#?
- The “using” statement is used to simplify the syntax for accessing resources. It allows using a resource without having to explicitly call the Dispose() method afterwards.
What is the difference between a string and a StringBuilder?
- A string object is immutable, which means that once it has been created, its value cannot be changed. A StringBuilder object, on the other hand, is mutable, so its value can be changed without having to create a new instance.
What is LINQ?
- LINQ stands for Language-Integrated Query and is a set of features that provide a simple and consistent syntax for querying data in collections. It also allows writing queries in an expressive way that can leverage the power of the .NET Framework.
What is anonymous type in C#?
- An anonymous type is a type that is defined at compile time and does not have a name. It is used to create objects without having to explicitly define a class for them.
What is the use of the “async” keyword in C#?
- The “async” keyword is used to create asynchronous methods. An asynchronous method runs on a separate thread and allows the main thread to continue executing while the asynchronous method is running.
What is the difference between the “await” and “yield” keywords?
- The “await” keyword is used to pause the execution of an asynchronous method until the awaitable task is completed. The “yield” keyword is used to restart and continue an iteration of a loop in a generator function.
What is covariant return type in C#?
- Covariant return type is a feature of the C# 4.5 language that allows the return type of a method to be a derived type from the declared return type in the parent method.
