설명
value 매개 변수는 틱으로 변환되고 해당 틱 수는 새 TimeSpan틱을 초기화하는 데 사용됩니다. 따라서 value 가장 가까운 밀리초까지만 정확한 것으로 간주됩니다. 데이터 형식의 Double 전체 자릿수 손실로 인해 이 변환은 둘 중 하나 MinValue 또는 MaxValue범위에서 가까운 값에 대한 값을 생성 OverflowException 할 수 있습니다. 예를 들어 OverflowException 다음과 같은 시도에서 개체를 인스턴스화 TimeSpan 하려고 합니다.
// The following throws an OverflowException at runtime
TimeSpan maxSpan = TimeSpan.FromMilliseconds(TimeSpan.MaxValue.TotalMilliseconds);
// The following throws an OverflowException at runtime
let maxSpan = TimeSpan.FromMilliseconds TimeSpan.MaxValue.TotalMilliseconds
' The following throws an OverflowException at runtime
Dim maxSpan As TimeSpan = TimeSpan.FromMilliseconds(TimeSpan.MaxValue.TotalMilliseconds)
