'Declaration
<CLSCompliantAttribute(False)> _
Public Shared Function ToUInt32 ( _
	value As ULong _
) As UInteger

Parameters

value
Type: System.UInt64

The 64-bit unsigned integer to convert.

Return Value

Type: System.UInt32
A 32-bit unsigned integer that is equivalent to value.

ExceptionCondition
OverflowException

value is greater than UInt32.MaxValue.

The following example attempts to convert each element in an unsigned long integer array to an unsigned integer value.

Dim numbers() As ULong = { UInt64.MinValue, 121, 340, UInt64.MaxValue }
Dim result As UInteger 

For Each number As ULong In numbers
   Try
      result = Convert.ToUInt32(number)
      Console.WriteLine("Converted the {0} value {1} to a {2} value {3}.", _
                        number.GetType().Name, number, _
                        result.GetType().Name, result)
   Catch e As OverflowException
      Console.WriteLine("The {0} value {1} is outside the range of the UInt32 type.", _
                        number.GetType().Name, number)
   End Try 
Next 
' The example displays the following output: 
'    Converted the UInt64 value 0 to a UInt32 value 0. 
'    Converted the UInt64 value 121 to a UInt32 value 121. 
'    Converted the UInt64 value 340 to a UInt32 value 340. 
'    The UInt64 value 18446744073709551615 is outside the range of the UInt32 type.
