Visual Basic: Dim name «As type» See notes to left. Constants use the same syntax, and: use Const instead of Dim; have a restriction to only certain primitive types Const name 1 «As type» = value, name 2 «As type» = value, ... Visual Basic .NET [10] The variable declaration syntax of VB.NET is unusually difficult to precisely describe.
Visual Basic is not case sensitive, which means that any combinations of upper and lower case letters in keywords are acceptable. Visual Studio automatically converts all Visual Basic keywords to the default capitalised forms, e.g. "Public", "If". C# is case sensitive and all C# keywords are in lower cases.
After Visual Basic .NET 2003, Microsoft dropped ".NET" from the name of the product, calling the next version Visual Basic 2005. For this release, Microsoft added many features intended to reinforce Visual Basic .NET's focus as a rapid application development platform and further differentiate it from C# ., including:
Visual Basic .NET is Microsoft's successor to Visual Basic 6.0, and part of Microsoft's .NET ecosystem (which over time has sometimes been called framework and core). It is not backwards compatible with Visual Basic 6.0. An automated conversion tool exists, but fully automated conversion for most projects is not possible.
C# 3.0 introduced type inference, allowing the type specifier of a variable declaration to be replaced by the keyword var, if its actual type can be statically determined from the initializer. This reduces repetition, especially for types with multiple generic type-parameters , and adheres more closely to the DRY principle.
In Visual Basic (and Visual Basic for Applications) the Variant data type is a tagged union that can be used to represent any other data type (for example, integer, floating-point, single- and double-precision, object, etc.) except fixed-length string type. In Visual Basic, any variable not declared explicitly or the type of which is not ...
The choice of a variable name should be mnemonic — that is, designed to indicate to the casual observer the intent of its use. One-character variable names should be avoided except for temporary "throwaway" variables. Common names for temporary variables are i, j, k, m, and n for integers; c, d, and e for characters. int i;
In computer programming, a declaration is a language construct specifying identifier properties: it declares a word's (identifier's) meaning. [1] Declarations are most commonly used for functions, variables, constants, and classes, but can also be used for other entities such as enumerations and type definitions. [1]
