out parameters are quite similar in their meaning.
out keywords are used to pass parameters to a method by reference. By default parameters are being passed to methods by value. Passing reference to variable instead of value means referenced variable might (or must) be modified/assigned by the method accepting this reference. The main difference is
out parameters must be set during the execution of the method and
ref parameters are not required to be set before returning. But there is more.
C# questions and answersQuestions and answers on the topic of C# programming language. C# is a modern multi-paradigm programming language created for developing .NET applications.
1. Write a method that takes in an input
string and returns
true if all the characters in the
string are unique and
false if there is even a single repeated character.
Encapsulation, in the context of C#, refers to an object's ability to hide data and behavior that are not necessary to its user. Encapsulation is used to restrict access to the members of a class so as to prevent the user of a given class from manipulating objects in ways that are not intended by the designer.
Basically, attribute is an information (metadata) that can be attached to your method, class, namespace, assembly etc. Once associated with a program entity, the metadata provided by an attribute can be queried at run time by using a technique called reflection and used in many ways.
C# 4.0 introduced a new type,
dynamic. The type is a static type, but an object of type
dynamic bypasses static type checking. In most cases, it functions like type
object. At compile time, an element that is typed as
dynamic is assumed to support any operation. Therefore, you do not have to be concerned about where the object gets its value from. However, if the code is not valid, errors are caught at run time.
In this article you can find four C# language specific questions for intermediate level with answers and explained code examples.
C# is one of the programming languages designed for the .NET Framework software development by Microsoft. It is most known language for this platform. C# is intended to be a modern, simple, general-purpose, object-oriented programming language. C# is a multi-paradigm programming language encompassing strong typing, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines.
