VB.NET Core Classes in a Nutshell

Name

IDictionary

Synopsis

This base interface for a collection of key/value elements defines the indexer (in C#, the this property — in VB.NET, the property marked as Default), as well as the Keys and Values properties that return collections containing the dictionary’s keys or values, respectively. This interface also defines the methods by which the entries may be modified, such as Add(), Clear(), and Remove().
