The indexer notation not only simplifies the syntax for client applications; it also makes the class, and its purpose more intuitive for other developers to understand. To declare an indexer on a class or struct, use the this keyword, as the following example shows:. Declaring an indexer will automatically generate a property named Item on the object. The Item property is not directly accessible from the instance member access expression.
Additionally, if you add your own Item property to an object with an indexer, you'll get a CS compiler error. To avoid this error, use the IndexerNameAttribute rename the indexer as detailed below. The type of an indexer and the type of its parameters must be at least as accessible as the indexer itself. For more information about accessibility levels, see Access Modifiers. For more information about how to use indexers with an interface, see Interface Indexers. The signature of an indexer consists of the number and types of its formal parameters.
It doesn't include the indexer type or the names of the formal parameters. If you declare more than one indexer in the same class, they must have different signatures.
An indexer value is not classified as a variable; therefore, you cannot pass an indexer value as a ref or out parameter. To provide the indexer with a name that other languages can use, use System. IndexerNameAttribute , as the following example shows:. This indexer will have the name TheItem , as it is overridden by the indexer name attribute. By default, the indexer name is Item. The following example shows how to declare a private array field, temps , and an indexer.
The indexer enables direct access to the instance tempRecord[i]. This page requires javascript to function properly. It seems that your browser does not have Javascript enabled.
