Decimal Explicit Conversion (Decimal to UInt16)

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

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.

' 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
