Příklady

Následující příklad používá MinValue MaxValue pole a k ověření, že Int64 hodnota spadá do rozsahu SByte typu před tím, než provede převod typu.The following example uses the MinValue and MaxValue fields to verify that an Int64 value is within the range of the SByte type before it performs a type conversion. Toto ověření zabrání OverflowException v době běhu.This verification prevents an OverflowException at run time.

long longValue = -130;
sbyte byteValue; 

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

   Console.WriteLine("Conversion failure: {0:n0} is {1} than {2}.",  
                     longValue, 
                     relationship, 
                     rangeLimit);
