Decimal Widening Conversion (Char to Decimal)

Defines an explicit conversion of a Unicode character to a Decimal.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
Public Shared Widening Operator CType ( _
	value As Char _
) As Decimal

Parameters

value
Type: System.Char

The Unicode character to convert.

Return Value

Type: System.Decimal
The converted Unicode character.

The overloads of the Widening method define the types from which the compiler can automatically convert a Decimal value without an explicit casting operator (in C#) or a call to a conversion function (in Visual Basic). They are widening conversions that do not involve data loss and do not throw an OverflowException exception.

The following example converts Char values (Unicode characters) to Decimal numbers. This conversion requires the op_Implicit operator in Visual Basic, but not in C# and C++.

Module Example
    Public Sub Main()
        ' Define an array of Char values. 
        Dim values() As Char = { ChrW(0), " "c, "*"c, "A"c, "a"c, 
                                 "{"c, "Æ"c }

        ' Convert each Char value to a Decimal. 
        For Each value In values
           Dim decValue As Decimal = Decimal.op_Implicit(value)
           Console.WriteLine("'{0}' ({1}) --> {2} ({3})", value,
                             value.GetType().Name, decValue,
                             decValue.GetType().Name)      
        Next 
    End Sub  
End Module 
' The example displays the following output: 
'       ' ' (Char) --> 0 (Decimal) 
'       ' ' (Char) --> 32 (Decimal) 
'       '*' (Char) --> 42 (Decimal) 
'       'A' (Char) --> 65 (Decimal) 
'       'a' (Char) --> 97 (Decimal) 
'       '{' (Char) --> 123 (Decimal) 
'       'Æ' (Char) --> 198 (Decimal)
