Convert.ToSByte Method (UInt16)


Converts the value of the specified 16-bit unsigned integer to the equivalent 8-bit signed integer.

This API is not CLS-compliant.

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

public static sbyte ToSByte(
	ushort value


Type: System.UInt16

The 16-bit unsigned integer to convert.

Return Value

Type: System.SByte

An 8-bit signed integer that is equivalent to value.

Exception Condition

value is greater than SByte.MaxValue.

The following example attempts to convert each element in an array of unsigned 16-bit integers to a signed byte.

ushort[] numbers = { UInt16.MinValue, 121, 340, UInt16.MaxValue };
sbyte result;

foreach (ushort 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:
//    Converted the UInt16 value 0 to the SByte value 0.
//    Converted the UInt16 value 121 to the SByte value 121.
//    The UInt16 value 340 is outside the range of the SByte type.
//    The UInt16 value 65535 is outside the range of the SByte type.
