Conversion Functions VB.NET

Visual Basic supports a number of ways of converting from one type to another. The conversion function would take such a value , String, expression and attempt to convert it. It the conversion 

is successful , the function would return an appropriate value.


1. CBool :- CBool Stands for Convert to Bool . It converts String , Charcter or numeric expression into boolean value .


Synatax :- CBool ( expression )


Example :-


Dim a, b As Integer
        a = 10
        b = 20
        Dim check As Boolean
        check = CBool(a > b)
        MsgBox(check)


2. CByte :- CByte stands for Convert to Byte Data Type. It converts numeric or floating values to byte Data Type.. If fractional part is given in variable-name then it will round off it to integer type.


Synatax :- CByte ( variable-name )


Example :-


Dim num1 as Double
Dim num2 as Byte
num1 = 2144.7865789
num2 = VByte( num1 )
Msgbox ( num2 )



3. CDate :- CDate Stands for Convert to Date type. It converts any valid form date format given as argument to it into Date


Syntax :- CDate ( Sting_Variable_Name )

Example :- 

Dim DateString As String 
Dim Finl_Date As Date
DateString = "July 3, 2013"
'The following line converts date format given in Date Type and give
it to Finl_Date

Finl_Date = CDate ( aDateString )

Msgbox ( Finl_Date.tostring())


4. CDbl :- CDbl stands for Convert to Double Data-Type. It converts 
the any given integer value to Double floating value


5. CInt :- CInt Stands for Convert to Integer Date -Type . CInt is 
widely used when converting from numbers or integers entered in string variable to convert it into integers to perform any Arithmetic operations.


Syntax :- 
CInt ( String_Variable )



Example :- 
Dim Var As String = "10"
        Dim num1, num2 As Integer
        num1 = CInt(Var)
        num2 = 10
        MsgBox(num1 + num2)


'It Returns 20




6. CChar :- CChar Stands for Convert to character. It Takes a String 
Variable as input Argument and as it convert it into char so it passes
the first character of specified string varible to a character 
variable


Syntax :-
CChar ( String_Variable )


Example :-
Dim String_variable As String = "bvf"
        Dim char_variable As Char
        char_variable = CChar(String_variable)
        MsgBox ( char_variable )


7. Cstr :- Cstr stands for convert to string . It converts any 
integer floating value given as input to CStr into string type value


Syntax :-
Cstr ( Variable_Name )


Example :-
Dim Str as String
Dim input as integer
input = 12267.9999
Str = Cstr ( input )
Msgbox ( Str )
' It Returns 12267.9999 


8. CUInt :- It converts given data value into CUint datatype . Here, 
UInt stands for Unsigned integer type.
Dim Double_Variable As Double 
Dim aUInt_Variable As UInteger
Double_Variable = 39.501
aUInt_Variable = CUInt(Double_Variable)

Msgbox ( aUInt_Variable )

'It Return 40


9. CShort :- It converts the given data value into short integer type
data value.

Syntax :- 
CShort ( Byte_Variable )

Example :-
Dim Byte_Variable As Byte 

Dim Short_Variable As Short

Byte_Variable = 100

Short_Variable = CShort(Byte_Variable)

Msgbox ( Short_Variable )





10. CDec :- It converts the given data value into Decimal Data-Type
value.

Syntax :-
CDec ( Variable_Name )

Example :-
Dim Double_Variable As Double 

Dim Decimal_Variable As Decimal

Double_Variable = 10000000.0587

Decimal_Variable = CDec(Double_Variable)

Msgbox ( Decinal_Variable )
