Decimal Narrowing Conversion (Decimal to UInt32)

Silverlight

Converts a Decimal to a 32-bit unsigned integer.

This API is not CLS-compliant. The CLS-compliant alternative is ToInt64(Decimal).

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

Syntax

```'Declaration
Public Shared Narrowing Operator CType ( _
value As Decimal _
) As UInteger
```

Parameters

value
Type: System.Decimal
A Decimal to convert.

Return Value

Type: System.UInt32
A 32-bit unsigned integer that represents the converted Decimal.

Exceptions

ExceptionCondition
OverflowException

value is negative or greater than UInt32.MaxValue.

Remarks

This operator supports the explicit conversion of a Decimal to a UInt32. 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 UInt32 value by using C# and Visual Basic. To perform a conversion that is independent of language, you can call the ToUInt32 or the Convert.ToUInt32(Decimal) method.

Examples

The following code example converts Decimal numbers to UInt32 values using the explicit Decimal to UInt32 conversion.

```
' Example of the explicit conversions from Decimal to Integer and
' Decimal to UInteger.
Module Example

Const formatter As String = "{0,17}{1,19}{2,19}"

' Convert the decimal argument catch exceptions that are thrown.
Public Sub DecimalToU_Int32(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal argument As Decimal)
Dim Int32Value As Object
Dim UInt32Value As Object

' Convert the argument to an int value.
Try
Int32Value = CInt(argument)
Catch ex As Exception
Int32Value = ex.GetType().Name
End Try

' Convert the argument to a uint value.
Try
UInt32Value = CUInt(argument)
Catch ex As Exception
UInt32Value = ex.GetType().Name
End Try

outputBlock.Text += String.Format(formatter, argument, _
Int32Value, UInt32Value) + vbCrLf
End Sub

Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
outputBlock.Text += String.Format(formatter, "Decimal Argument", _
"Integer/Exception", "UInteger/Exception") + vbCrLf
outputBlock.Text += String.Format(formatter, "----------------", _
"-------------", "--------------") + vbCrLf

' Convert decimal values and display the results.
DecimalToU_Int32(outputBlock, 123D)
DecimalToU_Int32(outputBlock, New Decimal(123000, 0, 0, False, 3))
DecimalToU_Int32(outputBlock, 123.999D)
DecimalToU_Int32(outputBlock, 4294967295.999D)
DecimalToU_Int32(outputBlock, 4294967296D)
DecimalToU_Int32(outputBlock, 2147483647.999D)
DecimalToU_Int32(outputBlock, 2147483648D)
DecimalToU_Int32(outputBlock, -0.999D)
DecimalToU_Int32(outputBlock, -1D)
DecimalToU_Int32(outputBlock, -2147483648.999D)
DecimalToU_Int32(outputBlock, -2147483649D)
End Sub
End Module
