Convert.ToSByte Method (Decimal)

Converts the value of the specified decimal number to an equivalent 8-bit signed integer.

This API is not CLS-compliant. 

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

[CLSCompliantAttribute(false)]
public static sbyte ToSByte(
	decimal value
)

Parameters

value
Type: System.Decimal

The decimal number to convert.

Return Value

Type: System.SByte
value, rounded to the nearest 8-bit signed integer. If value is halfway between two whole numbers, the even number is returned; that is, 4.5 is converted to 4, and 5.5 is converted to 6.

ExceptionCondition
OverflowException

value is greater than SByte.MaxValue or less than SByte.MinValue.

The following example attempts to convert each element in an array of Decimal values to a signed byte.

decimal[] numbers = { Decimal.MinValue, -129.5m, -12.7m, 0m, 16m,
                      103.6m, 255.0m, Decimal.MaxValue };
sbyte result;

foreach (decimal number in numbers)
{
   try {
      result = Convert.ToSByte(number);
      Console.WriteLine("Converted the {0} value {1} to the {2} value {3}.",
                        number.GetType().Name, number,
                        result.GetType().Name, result);
   }
   catch (OverflowException) {
      Console.WriteLine("The {0} value {1} is outside the range of the SByte type.",
                        number.GetType().Name, number);
   }
}                         
// The example displays the following output: 
//    The Decimal value -79228162514264337593543950335 is outside the range of the SByte type. 
//    The Decimal value -129.5 is outside the range of the SByte type. 
//    Converted the Decimal value -12.7 to the SByte value -13. 
//    Converted the Decimal value 0 to the SByte value 0. 
//    Converted the Decimal value 16 to the SByte value 16. 
//    Converted the Decimal value 103.6 to the SByte value 104. 
//    The Decimal value 255 is outside the range of the SByte type. 
//    The Decimal value 79228162514264337593543950335 is outside the range of the SByte type.
