SByte.MaxValue Pole

Definicja

Reprezentuje największą możliwą wartość SByte.Represents the largest possible value of SByte. To pole jest stałe.This field is constant.

public: System::SByte MaxValue = 127;
public const sbyte MaxValue = 127;
val mutable MaxValue : sbyte
Public Const MaxValue As SByte  = 127

Wartość pola

Przykłady

Poniższy przykład używa pól MinValue i MaxValue, aby sprawdzić, czy wartość Int64 należy do zakresu typu SByte przed wykonaniem konwersji 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. Ta weryfikacja uniemożliwia OverflowException w czasie wykonywania.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);
}       
Dim longValue As Long = -130
Dim byteValue As SByte 

If longValue <= SByte.MaxValue AndAlso _
   longValue >= SByte.MinValue Then
   byteValue = CSByte(longValue)
   Console.WriteLine("Converted long integer value to {0}.", byteValue)
Else
   Dim rangeLimit As SByte
   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}.", _ 
                     longValue, _
                     relationship, _
                     rangeLimit)
End If       

Uwagi

Wartość tej stałej to 127; oznacza to, że szesnastkowa 0x7F.The value of this constant is 127; that is, hexadecimal 0x7F.
