Ejemplos

En el ejemplo siguiente se usan los campos MinValue y MaxValue para comprobar que un valor de Int64 está dentro del intervalo del tipo de SByte antes de realizar una conversión de tipos.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. Esta comprobación evita un OverflowException en tiempo de ejecución.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);
}

   longValue >= SByte.MinValue Then

   Console.WriteLine("Converted long integer value to {0}.", byteValue)
Else

   Dim relationship As String
   
   If longValue > SByte.MaxValue Then
      rangeLimit = SByte.MaxValue
      relationship = "greater"
   Else
      rangeLimit = SByte.MinValue
      relationship = "less"
   End If       

   Console.WriteLine("Conversion failure: {0:n0} is {1} than {2}.", _
