Exemples

L’exemple suivant utilise les MinValue champs MaxValue et pour vérifier qu’une Int64 valeur est comprise dans la UInt32 plage du type avant d’effectuer une conversion de type.The following example uses the MinValue and MaxValue fields to verify that an Int64 value is within the range of the UInt32 type before it performs a type conversion. Cette vérification empêche un OverflowException au moment de l’exécution.This verification prevents an OverflowException at run time.

long longValue = long.MaxValue / 2;
uint integerValue; 

if (longValue <= uint.MaxValue && 
    longValue >= uint.MinValue)
{    
   integerValue = (uint) longValue;
   Console.WriteLine("Converted long integer value to {0:n0}.", 
                     integerValue);
}   
else
{
   uint rangeLimit;
   string relationship;
   
   if (longValue > uint.MaxValue)
   {
      rangeLimit = uint.MaxValue;
      relationship = "greater";
   }   
   else
   {
      rangeLimit = uint.MinValue;
      relationship = "less";
   }       

   Console.WriteLine("Conversion failure: {0:n0} is {1} than {2:n0}",  
                     longValue, 
                     relationship, 
                     rangeLimit);
}       
Dim longValue As Long = Long.MaxValue \ 2
Dim integerValue As UInteger 

If longValue <= UInteger.MaxValue AndAlso _
   longValue >= UInteger.MinValue Then
   integerValue = CUInt(longValue)
   Console.WriteLine("Converted long integer value to {0:n0}.", _
                     integerValue)
Else
   Dim rangeLimit As UInteger
   Dim relationship As String
   
   If longValue > UInteger.MaxValue Then
      rangeLimit = UInteger.MaxValue
      relationship = "greater"
   Else
      rangeLimit = UInteger.MinValue
      relationship = "less"
   End If
