## Comentários

O `value` parâmetro é convertido em tiques e esse número de tiques é usado para inicializar o novo TimeSpan.The `value` parameter is converted to ticks, and that number of ticks is used to initialize the new TimeSpan. Por isso, `value` só será considerado somente preciso no milissegundo mais próximo.Therefore, `value` will only be considered accurate to the nearest millisecond. Observe que, devido à Double perda de precisão do tipo de dados, essa conversão pode gerar um OverflowException para valores próximos a, mas ainda MinValue no intervalo de ou MaxValue.Note that, because of the loss of precision of the Double data type, this conversion can generate an OverflowException for values that are near to but still in the range of either MinValue or MaxValue. Por exemplo, isso faz um OverflowException na tentativa a seguir tentar criar uma instância de um objeto TimeSpan.For example, this causes an OverflowException in the following attempt to instantiate a TimeSpan object.

``````// The following throws an OverflowException at runtime
TimeSpan maxSpan = TimeSpan.FromMilliseconds(TimeSpan.MaxValue.TotalMilliseconds);
``````
``````' The following throws an OverflowException at runtime
Dim maxSpan As TimeSpan = TimeSpan.FromMilliseconds(TimeSpan.MaxValue.TotalMilliseconds)
