Convert.ToSByte Method (Int32)

Converts the value of the specified 32-bit signed integer to an equivalent 8-bit signed integer.

This API is not CLS-compliant. 

Namespace:  System
Assemblies:   System.Runtime.Extensions (in System.Runtime.Extensions.dll)
  mscorlib (in mscorlib.dll)

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

Parameters

value
Type: System.Int32

The 32-bit signed integer to convert.

Return Value

Type: System.SByte
An 8-bit signed integer that is equivalent to value.

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 signed integers to a signed byte.

int[] numbers = { Int32.MinValue, -1, 0, 121, 340, Int32.MaxValue };
sbyte result;

foreach (int 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 Int32 value -2147483648 is outside the range of the SByte type. 
//    Converted the Int32 value -1 to the SByte value -1. 
//    Converted the Int32 value 0 to the SByte value 0. 
//    Converted the Int32 value 121 to the SByte value 121. 
//    The Int32 value 340 is outside the range of the SByte type. 
//    The Int32 value 2147483647 is outside the range of the SByte type.
