Representa el menor valor posible de SByte. Este campo es constante.

public: System::SByte MinValue = -128;
public const sbyte MinValue = -128;
val mutable MinValue : sbyte
Public Const MinValue As SByte  = -128

Valor de campo

Value = -128
SByte

Ejemplos

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

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);
}

let longValue = -130L

if longValue <= int64 SByte.MaxValue && longValue >= int64 SByte.MinValue then
    let byteValue = int8 longValue
    printfn $"Converted long integer value to {byteValue}."
else
    let rangeLimit, relationship =
        if longValue > int64 SByte.MaxValue then
            SByte.MaxValue, "greater"
        else
            SByte.MinValue, "less"

    printfn $"Conversion failure: {longValue:n0} is {relationship} than {rangeLimit}."
