Decimal ExplicitNarrowingExplicitExplicit Conversion (Decimal to UInt32)
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
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
Public Shared Narrowing Operator CType ( _
value As Decimal _
) As UInteger
public static explicit operator uint (
decimal value
)
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
Exception | Condition |
---|---|
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

outputBlock.Text += String.Format(formatter, "Decimal Argument", _
"Integer/Exception", "UInteger/Exception") + vbCrLf
outputBlock.Text += String.Format(formatter, "----------------", _
