Important

Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

Represents the largest possible value of SByte. This field is constant.

public: System::SByte MaxValue = 127;

public const sbyte MaxValue = 127;

val mutable MaxValue : sbyte

Public Const MaxValue As SByte  = 127

Field Value

Value = 127

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);
}

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}."

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

Remarks

The value of this constant is 127; that is, hexadecimal 0x7F.
