Decimal Explicit Conversion (Decimal to UInt16)
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Converts a Decimal to a 16-bit unsigned integer.
This API is not CLS-compliant.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Shared Narrowing Operator CType ( _
value As Decimal _
) As UShort
public static explicit operator ushort (
decimal value
)
Parameters
- value
Type: System.Decimal
A Decimal to convert.
Return Value
Type: System.UInt16
A 16-bit unsigned integer that represents the converted Decimal.
Exceptions
| Exception | Condition |
|---|---|
| OverflowException | value is greater than UInt16.MaxValue or less than UInt16.MinValue. |
Remarks
This operator supports the explicit conversion of a Decimal to a UInt16. The syntax for such explicit conversions is language-dependent, and individual language compilers can provide different implementations and return different results. The example illustrates the different return values when you explicitly convert a Decimal value to a UInt16 value by using C# and Visual Basic. To perform a conversion that is independent of language, you can call the ToUInt16 or the Convert.ToUInt16(Decimal) method.
Examples
The following code example converts Decimal numbers to UInt16 values using the explicit Decimal to UInt16 conversion.
' Example of the explicit conversions from Decimal to Short and
' Decimal to UShort.
Module Example
Const formatter As String = "{0,16}{1,19}{2,19}"
' Convert the decimal argument and catch exceptions that are thrown.
Public Sub DecimalToU_Int16(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal argument As Decimal)
Dim Int16Value As Object
Dim UInt16Value As Object
' Convert the argument to a Short value.
Try
Int16Value = CShort(argument)
Catch ex As Exception
Int16Value = ex.GetType().Name
End Try
' Convert the argument to a UShort value.
Try
UInt16Value = CUShort(argument)
Catch ex As Exception
UInt16Value = ex.GetType().Name
End Try
outputBlock.Text += String.Format(formatter, argument, _
Int16Value, UInt16Value) + vbCrLf
End Sub
Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
outputBlock.Text += String.Format(formatter, "Decimal argument", _
"Short/Exception", "UShort/Exception") + vbCrLf
outputBlock.Text += String.Format(formatter, "----------------", _
"---------------", "----------------") + vbCrLf
' Convert decimal values and display the results.
