Why do we use indexers in C#?
The indexer enables direct access to the instance tempRecord[i] .
The alternative to using the indexer is to declare the array as a public member and access its members, tempRecord.
temps[i] , directly.
Notice that when an indexer’s access is evaluated, for example, in a Console..
What are indexers in C#?
Indexers allow instances of a class or struct to be indexed just like arrays. The indexed value can be set or retrieved without explicitly specifying a type or instance member. Indexers resemble properties except that their accessors take parameters.
What are Properties C#?
A property is a member that provides a flexible mechanism to read, write, or compute the value of a private field. Properties can be used as if they are public data members, but they are actually special methods called accessors.
What are the advantages of properties in C#?
The main advantage of properties is that they allow us to encapsulate our data inside our class in such a way that we can control access to our class’s data through only the properties and not by allowing outside programs to access our fields directly.
What are tuples in C #?
What does => mean in C#?
The => token is supported in two forms: as the lambda operator and as a separator of a member name and the member implementation in an expression body definition.
What is namespace C#?
Advertisements. A namespace is designed for providing a way to keep one set of names separate from another. The class names declared in one namespace does not conflict with the same class names declared in another.
Can we have static indexer in C#?
You can’t make a Static Indexer in C#… The CLR can, but you can’t with C#. You can’t even trick the compiler with VB.NET.
Why do we need Generics in C#?
Generics in C# is its most powerful feature. It allows you to define the type-safe data structures. … Generic types perform better than normal system types because they reduce the need for boxing, unboxing, and type casting the variables or objects. Parameter types are specified in generic class creation.
What are C# attributes and its significance?
An attribute is a declarative tag that is used to convey information to runtime about the behaviors of various elements like classes, methods, structures, enumerators, assemblies etc. in your program. You can add declarative information to a program by using an attribute.
What is the difference between properties and indexer in C#?
Properties are invoked through a described name and can be declared as a static or an instance member. Indexers in C# are data members that act as an array and allow you to access data within objects to be indexed in the same way.
What is the generic in C#?
Generics allow you to define the specification of the data type of programming elements in a class or a method, until it is actually used in the program. In other words, generics allow you to write a class or method that can work with any data type.
What are events in C#?
Events enable a class or object to notify other classes or objects when something of interest occurs. The class that sends (or raises) the event is called the publisher and the classes that receive (or handle) the event are called subscribers.
What indexer means?
A person or program which creates indexes. noun. 1. 0. (computing, programming.NET) A special property of a class allowing objects of the class to be accessed by index as though they were arrays or hash tables.
What is an indexer machine?
An indexing head, also known as a dividing head or spiral head, is a specialized tool that allows a workpiece to be circularly indexed; that is, easily and precisely rotated to preset angles or circular divisions. … The workpiece is held in the indexing head in the same manner as a metalworking lathe.
