Question

How would one go about implementing the indexing ‘operator’ on a class in C# ?

class Foo {  }  Foo f = new Foo(); f['key'] = 'some val'; f['other key'] = 'some other val'; 

in C# ? Searched MSDN but came up empty.

Here is an example using a dictionary as storage:

public class Foo {      private Dictionary<string, string> _items;      public Foo() {         _items = new Dictionary<string, string>();     }      public string this[string key] {         get {             return _items[key];         }         set {             _items[key]=value;         }     }  }
