어셈블리: mscorlib(mscorlib.dll)
구문
‘선언
Public Shared Function ToByte ( _
value As Decimal _
) As Byte
‘사용 방법
Dim value As Decimal
Dim returnValue As Byte
returnValue = Decimal.ToByte(value)
public static byte ToByte (
decimal value
)
public:

매개 변수
- value
Decimal 값입니다.
반환 값
value에 해당하는 8비트의 부호 없는 정수입니다.
예외
| 예외 형식 | 조건 |
|---|---|
value가 Byte.MinValue보다 작거나 Byte.MaxValue보다 큰 경우 |
설명
매개 변수 value는 0에 가장 가까운 정수 값으로 반올림된 다음 결과를 반환합니다.
예제
다음 코드 예제에서는 ToByte 메서드를 사용하여 Decimal 숫자를 Byte 값으로 변환합니다.
