Exemples

L’exemple suivant montre comment utiliser le MaxValue champ pour passer en écran les entrées de variables pour les valeurs qui se trouvent en dehors de la plage de valeurs d’octets possibles.

public:
   void MinMaxFields( Int32 numberToSet )
   {
      if ( numberToSet <= (Int32)Byte::MaxValue && numberToSet >= (Int32)Byte::MinValue )
      {
         
         // You must explicitly convert an integer to a byte.
         MemberByte = (Byte)numberToSet;
         
         // Displays MemberByte using the ToString() method.
         Console::WriteLine(  "The MemberByte value is {0}", MemberByte.ToString() );
      }
      else
      {
         Console::WriteLine(  "The value {0} is outside of the range of possible Byte values", numberToSet.ToString() );
      }
   }

public void MinMaxFields(int numberToSet)
{
   if(numberToSet <= (int)Byte.MaxValue && numberToSet >= (int)Byte.MinValue)
   {
      // You must explicitly convert an integer to a byte.
      MemberByte = (Byte)numberToSet;

      // Displays MemberByte using the ToString() method.
      Console.WriteLine("The MemberByte value is {0}", MemberByte.ToString());
   }
   else
   {
      Console.WriteLine("The value {0} is outside of the range of possible Byte values", numberToSet.ToString());
   }
}

let minMaxFields numberToSet =
    if numberToSet <= int Byte.MaxValue && numberToSet >= int Byte.MinValue then
        // You must explicitly convert an integer to a byte.
        let myByte = byte numberToSet

        printfn $"The MemberByte value is {myByte}"
    else
        printfn $"The value {numberToSet} is outside of the range of possible Byte values"

Public Sub MinMaxFields(ByVal numberToSet As Integer)
   If numberToSet <= CInt([Byte].MaxValue) And numberToSet >= CInt([Byte].MinValue) Then
      ' You must explicitly convert an integer to a byte.
      MemberByte = CType(numberToSet, [Byte])

      ' Displays MemberByte using the ToString() method.
      Console.WriteLine("The MemberByte value is {0}.", MemberByte.ToString())
   Else
      Console.WriteLine("The value {0} is outside of the range of possible Byte values.", numberToSet.ToString())
   End If
End Sub
