The following example attempts to convert each element in an array of long integers to a signed byte.
Dim numbers() As ULong = { UInt64.MinValue, 121, 340, UInt64.MaxValue } Dim result As SByte For Each number As ULong In numbers Try result = Convert.ToSByte(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 SByte type.", _ number.GetType().Name, number) End Try Next ' The example displays the following output: ' Converted the UInt64 value 0 to the SByte value 0. ' Converted the UInt64 value 121 to the SByte value 121. ' The UInt64 value 340 is outside the range of the SByte type. ' The UInt64 value 18446744073709551615 is outside the range of the SByte type.
