Decimal Implicit Conversion (Char to Decimal)
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Converts a Unicode character to a Decimal.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Shared Widening Operator CType ( _
value As Char _
) As Decimal
public static implicit operator decimal (
char value
)
Parameters
- value
Type: System.Char
A Unicode character.
Return Value
Type: System.Decimal
A Decimal that represents the converted Unicode character.
Examples
The following code example converts Char values (Unicode characters) to Decimal numbers using the Char to Decimal conversion. This conversion is implicit in C#, but requires the op_Implicit operator in Visual Basic and C++. Implicit conversions to Decimal use other methods in these languages.
' Example of the op_Implicit conversion from Char to Decimal.
Imports System.Globalization
Module Example
Const formatter As String = _
"{0,6}{1,15}{2,10:X8}{3,9:X8}{4,9:X8}{5,9:X8}"
' Convert the Char argument and display the Decimal value.
Sub DecimalFromChar(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal argument As Char)
Dim decValue As Decimal
Dim bits() As Integer
' The compiler invokes a constructor in Visual Basic
' unless op_Implicit is explicitly called.
decValue = Decimal.op_Implicit(argument)
' Display the Decimal and its binary representation.
bits = Decimal.GetBits(decValue)
outputBlock.Text &= String.Format(formatter, argument, decValue, _
bits(3), bits(2), bits(1), bits(0)) & vbCrLf
End Sub
Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)

"to Decimal generates the " & vbCrLf & "following " & _
"output. It displays the Decimal value and its " & _
