TimeSpan.Negate Método
Definición
Importante
Parte de la información hace referencia a la versión preliminar del producto, que puede haberse modificado sustancialmente antes de lanzar la versión definitiva. Microsoft no otorga ninguna garantía, explícita o implícita, con respecto a la información proporcionada aquí.
Devuelve un nuevo TimeSpan objeto cuyo valor es el valor negado de esta instancia.
public:
TimeSpan Negate();public TimeSpan Negate();member this.Negate : unit -> TimeSpanPublic Function Negate () As TimeSpanDevoluciones
Nuevo objeto con el mismo valor numérico que esta instancia, pero con el signo opuesto.
Excepciones
El valor negado de esta instancia no se puede representar mediante ; TimeSpanes decir, el valor de esta instancia es TimeSpan.MinValue.
Ejemplos
En el ejemplo siguiente se aplica el Negate método a varios TimeSpan objetos.
// Example of the TimeSpan.Duration( ) and TimeSpan.Negate( ) methods,
// and the TimeSpan Unary Negation and Unary Plus operators.
using System;
class DuraNegaUnaryDemo
{
const string dataFmt = "{0,22}{1,22}{2,22}" ;
static void ShowDurationNegate( TimeSpan interval )
{
// Display the TimeSpan value and the results of the
// Duration and Negate methods.
Console.WriteLine( dataFmt,
interval, interval.Duration( ), interval.Negate( ) );
}
static void Main()
{
Console.WriteLine(
"This example of TimeSpan.Duration( ), " +
"TimeSpan.Negate( ), \nand the TimeSpan Unary " +
"Negation and Unary Plus operators \n" +

"TimeSpan", "Duration( )", "Negate( )" );
Console.WriteLine( dataFmt,
"--------", "-----------", "---------" );
