UInt32.MaxValue Campo

Nell'esempio seguente vengono utilizzati i MinValue campi e MaxValue per verificare che un Int64 valore sia compreso nell'intervallo del tipo prima di UInt32 eseguire una conversione del tipo. Questa verifica impedisce un oggetto OverflowException in fase di esecuzione.

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,
