What is reflection and why we need it in C#?

Reflection provides objects (of type Type) that describe assemblies, modules, and types. You can use reflection to dynamically create an instance of a type, bind the type to an existing object, or get the type from an existing object and invoke its methods or access its fields and properties.

What is reflection in OOP?

Reflection can be used for observing and modifying program execution at runtime. In object-oriented programming languages such as Java, reflection allows inspection of classes, interfaces, fields and methods at runtime without knowing the names of the interfaces, fields, methods at compile time.

What is reflection in C# interview?

In simple words : Reflection is used when you want to inspect / determine / modify contents of an assembly. Reflection is used get the metadata information of an assembly.

What is reflection in dotnet?

NET Reflection. NET Reflection allows application to collect information about itself and also manipulate on itself. It can be used effectively to find all the types in an assembly and/or dynamically invoke methods in an assembly. This includes information about the type, properties, methods and events of an object.

When should we use reflection?

Reflection gives us information about the class to which an object belongs and also the methods of that class which can be executed by using the object. Through reflection we can invoke methods at runtime irrespective of the access specifier used with them.

Is it OK to use reflection in C#?

Reflection in C# is used to retrieve metadata on types at runtime. In using reflection, you get objects of the type “Type” that can be used to represent assemblies, types, or modules. You can use reflection to create an instance of a type dynamically and even invoke methods of the type. The types defined in the System.

Why is reflection useful?

The most useful reflection involves the conscious consideration and analysis of beliefs and actions for the purpose of learning. Reflection gives the brain an opportunity to pause amidst the chaos, untangle and sort through observations and experiences, consider multiple possible interpretations, and create meaning.

Does C have reflection?

Introduction to Reflection in C++ In C++ reflection has been added at later stage using RTTI but supports only have some restrictive features.

WHAT IS interface in C# net?

Interface in C# is a blueprint of a class. It is like abstract class because all the methods which are declared inside the interface are abstract methods. It cannot have method body and cannot be instantiated. It is used to achieve multiple inheritance which can’t be achieved by class.

What is type safe in C#?

C# language is a type safe language. Type safety in . NET has been introduced to prevent the objects of one type from peeking into the memory assigned for the other object. Writing safe code also means to prevent data loss during conversion of one type to another.

Is reflection slow C#?

Its slower compared to non-reflective code. The important thing is not if its slow, but if its slow where it counts. For instance, if you instantiate objects using reflection in web environment where expected concurency can rise up to 10K, it will be slow.

What are the possible uses of reflection?

What is the use of reflection in C?

With reflection in C#, you can dynamically create an instance of a type and bind that type to an existing object. Moreover, you can get the type from an existing object and access its properties.

What is the use of reflection in Java?

Reflection provides objects (of type Type) that describe assemblies, modules, and types. You can use reflection to dynamically create an instance of a type, bind the type to an existing object, or get the type from an existing object and invoke its methods or access its fields and properties.

What are some of your favorite uses of reflection?

Invoking a method that’s defined at runtime. Many other other on the same vein. However, one of my favorite uses of reflection is to find properties that have been marked with attributes. For example, I’ve written attributes that mark which properties in my classes should be indexed using Lucene.

What is the use of reflection in Assembly?

Reflection allows an application to collect information about itself and also to manipulate on itself. It can be used to find all types in an assembly and/or dynamically invoke methods in an assembly.
