The compiler automatically generates names for these methods by prepending get_ and set_ to the indexer name . Because the C# syntax for an indexer doesn t allow the developer to specify an indexer name, the C# compiler team had to choose a default name to use for the accessor methods; they chose Item . Therefore, the method names emitted by the compiler are get_Item and set_Item . When examining the .NET Framework Reference documentation, you can tell if a type offers an indexer by looking for a property named Item . For example, the System.Collections.Generic.List type offers a public instance property named Item; this property is List s indexer . When you program in C#, you never see the name of Item, so you don t normally care that the compiler has chosen this name for you . However, if you re designing an indexer for a type that code written in other programming languages will be accessing, you might want to change the default name, Item, given to your indexer s get and set accessor methods . C# allows you to rename these methods by applying the System.Runtime.CompilerServices.IndexerNameAttribute custom attribute to the indexer . The following code demonstrates how to do this:
