Convert.ToSByte Method (Int64)

Converts the value of the specified 64-bit signed integer 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(
	long value
)

Parameters

value
Type: System.Int64
The 64-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 long integers to a signed byte.


long[] numbers = { Int64.MinValue, -1, 0, 121, 340, Int64.MaxValue };
sbyte result;
foreach (long 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 Int64 value -9223372036854775808 is outside the range of the SByte type.
//    Converted the Int64 value -1 to the SByte value -1.
//    Converted the Int64 value 0 to the SByte value 0.
//    Converted the Int64 value 121 to the SByte value 121.
//    The Int64 value 340 is outside the range of the SByte type.
//    The Int64 value 9223372036854775807 is outside the range of the SByte type.
