Decimal.ToUInt32 Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Converts the value of the specified Decimal to the equivalent 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
<CLSCompliantAttribute(False)> _
<SecuritySafeCriticalAttribute> _
Public Shared Function ToUInt32 ( _
    d As Decimal _
) As UInteger
[CLSCompliantAttribute(false)]
[SecuritySafeCriticalAttribute]
public static uint ToUInt32(
    decimal d
)

Parameters

Return Value

Type: System.UInt32
A 32-bit unsigned integer equivalent to the value of d.

Exceptions

Exception Condition
OverflowException

d is negative or greater than UInt32.MaxValue.

Remarks

The return value is the integral part of the decimal value; fractional digits are truncated.

Examples

The following code example converts Decimal numbers to UInt32 values using the ToUInt32 method.

' Example of the Decimal.ToInt32 and Decimal.ToUInt32 methods.

Module Example

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

   ' Get the exception type name; remove the namespace prefix.

      Return exceptionType.Substring( _
          exceptionType.LastIndexOf("."c) + 1)
