SByte.MinValue Field

public: System::SByte MinValue = -128;

public const sbyte MinValue = -128;

val mutable MinValue : sbyte

Public Const MinValue As SByte  = -128

Field Value

SByte

Examples

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. 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

Remarks

The value of this constant is -128; that is, hexadecimal 0x80.
