Important

This API is not CLS-compliant.

CLS-compliant alternative
System.Decimal.ToInt64(Decimal)

Converts the value of the specified Decimal to the equivalent 32-bit unsigned integer.

public:
 static System::UInt32 ToUInt32(System::Decimal d);
[System.CLSCompliant(false)]
public static uint ToUInt32(decimal d);
[<System.CLSCompliant(false)>]
static member ToUInt32 : decimal -> uint32
Public Shared Function ToUInt32 (d As Decimal) As UInteger

Parameters

d
Decimal

The decimal number to convert.

Returns

UInt32

A 32-bit unsigned integer equivalent to the value of d.

Attributes
CLSCompliantAttribute

Exceptions

OverflowException

d is negative or greater than UInt32.MaxValue.

Examples

The following example uses the ToUInt32 method to convert decimal numbers to UInt32 values.

using System;

class Example
{
   public static void Main( )
   {
      decimal[] values = { 123m, new decimal(123000, 0, 0, false, 3),

                           4294967296m, 2147483647.999m, 2147483648m,

      foreach (var value in values) {
         try {
            uint number = Decimal.ToUInt32(value);
            Console.WriteLine("{0} --> {1}", value, number);
         }
         catch (OverflowException e)
         {
             Console.WriteLine("{0}: {1}", e.GetType().Name, value);
         }

Remarks

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

You can also convert a Decimal value to an 32-bit unsigned integer by using the Explicit assignment operator. Because the operator performs a narrowing conversion, you must use a casting operator in C# or a conversion function in Visual Basic.
