What is iterable in C#?

C# iterator is a method. It is used to iterate the elements of a collection, array or list. An iterator uses yield return statement to return each element at a time. The iterator remembers the current location and in next iteration, it returns the next element.

What is an iterable class?

Last update: 2020-05-25. The Java Iterable interface represents a collection of objects which is iterable – meaning which can be iterated. This means, that a class that implements the Java Iterable interface can have its elements iterated.

Does C# have iterators?

An iterator is a method in C# which is used in an array or in collections like the list, etc. to retrieve elements one by one. Or in other words, we can say that an iterator is used to perform an iteration over the collections. This feature is introduced in C# 2.0.

How do I return an iterator in C#?

The sequence returned from an iterator method can be consumed by using a foreach statement or LINQ query. Each iteration of the foreach loop calls the iterator method. When a yield return statement is reached in the iterator method, expression is returned, and the current location in code is retained.

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 is a generic type in C#?

Generic means the general form, not specific. In C#, generic means not specific to a particular data type. C# allows you to define generic classes, interfaces, abstract classes, fields, methods, static methods, properties, events, delegates, and operators using the type parameter and without the specific data type.

How do you make an iterable class?

To make your class Iterable we need to override __iter__() function inside our class i.e. This function should return the object of Iterator class associated with this Iterable class. Contains List of Junior and senior team members and also overrides the __iter__() function.

How do you iterate over an object in C#?

“c# loop through object” Code Answer’s

foreach (PropertyInfo prop in someObject. GetType(). GetProperties())
{
Console. WriteLine($”{prop.Name}: {prop.GetValue(someObject, null)}”);
}

What is the difference between yield and return in C#?

The only difference between yield and return is whenever yield statement is encountered in a function, the execution of function is suspended and a value is send back to the caller but because of yield whenever the function is called again, the execution of function begin where it left off previously.

How do you use yield return?

To use “yield return”, you just need to create a method with a return type that is an IEnumerable (arrays and collections in. Net implements IEnumerable interface) with a loop and use “yield return” to return a value to set in the loop body.

Why do we need indexers in C#?

Indexers are a syntactic convenience that enable you to create a class, struct, or interface that client applications can access as an array. Indexers are most frequently implemented in types whose primary purpose is to encapsulate an internal collection or array.
