![]() ![]() Initializer − Optional if New is not specified. It specifies the data type of the variable. It creates a new instance of the class when the Dim statement runs.ĭatatype − Required if Option Strict is On. It provides list of bounds of each dimension of an array variable. Variablename − is the name of the variableīoundslist − optional. Variablelist provides the list of variables declared.Įach variable in the variable list has the following syntax and parts − ![]() WithEvents specifies that the variable is used to respond to events raised by the instance assigned to the variable. ReadOnly means the variable can be read, but not written. Static indicates that the variable will retain its value, even when the after termination of the procedure in which it is declared. Shadows indicate that the variable re-declares and hides an identically named element, or set of overloaded elements, in a base class. Shared declares a shared variable, which is not associated with any specific instance of a class or structure, rather available to all the instances of the class or structure. Optional.Īccessmodifier defines the access levels of the variables, it has values as - Public, Protected, Friend, Protected Friend and Private. Dim variablelistĪttributelist is a list of attributes that apply to the variable. Syntax for variable declaration in VB.Net is − The Dim statement is used at module, class, structure, procedure or block level. The Dim statement is used for variable declaration and storage allocation for one or more variables. We will discuss date types and Classes in subsequent chapters. VB.Net also allows defining other value types of variable like Enum and reference types of variables like Class. SByte, Byte, Short, UShort, Integer, UInteger, Long, ULong and Char The basic value types provided in VB.Net can be categorized as − Type We have already discussed various data types. Each variable in VB.Net has a specific type, which determines the size and layout of the variable's memory the range of values that can be stored within that memory and the set of operations that can be applied to the variable. A variable is nothing but a name given to a storage area that our programs can manipulate. ![]()
