Question - What is an Indexer in C#, and how do you create one?
Answer -
Also known as an indexed property, an indexer is a class property allowing accessing a member variable of some class using features of an array. Used for treating an object as an array, indexer allows using classes more intuitively. Although not an essential part of the object-oriented programming, indexers are a smart way of using arrays. As such, they are also called smart arrays. Defining an indexer enables creating classes that act like virtual arrays. Instances of such classes can be accessed using the [] array access operator. The general syntax for creating an indexer in C# is:
< modifier > <
return type > this[argument list] {
get {
// the get block code
}
set {
// the set block code
}
}
