| OverflowException | value is less than zero. |
The following example attempts to convert each element in an array of long integers to an unsigned long integer.
Dim numbers() As Long = { Int64.MinValue, -19432, -18, 0, 121, 340, Int64.MaxValue } Dim result As ULong For Each number As Long In numbers Try result = Convert.ToUInt64(number) Console.WriteLine("Converted the {0} value {1} to the {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 UInt64 type.", _ number.GetType().Name, number) End Try Next ' The example displays the following output: ' The Int64 value -9223372036854775808 is outside the range of the UInt64 type. ' The Int64 value -19432 is outside the range of the UInt64 type. ' The Int64 value -18 is outside the range of the UInt64 type. ' Converted the Int64 value 0 to the UInt64 value 0. ' Converted the Int64 value 121 to the UInt64 value 121. ' Converted the Int64 value 340 to the UInt64 value 340. ' Converted the Int64 value 9223372036854775807 to the UInt64 value 9223372036854775807.
