Two kinds of types are supported in VB.NET, value types and reference types. The difference between these two kinds of types is in the way the variables of each type behave.
Unlike reference types, variables of value types contain the actual data they represent. Value types consist of primitives (except Object and String), enumerations, and structures.
Primitive types are shorthand for CLR types found in the .NET platform. Table C.3 outlines each of the value types found in VB.NET as well as the system-provided type to which it corresponds.
|Short||System.Int16||16-bit signed integral type|
|Integer||System.Int32||32-bit signed integral type|
