Campo TimeSpan.MinValue

Aggiornamento: novembre 2007

Rappresenta il valore TimeSpan minimo. Questo campo è di sola lettura.

Spazio dei nomi:  System
Assembly:  mscorlib (in mscorlib.dll)

public static readonly TimeSpan MinValue
public static final TimeSpan MinValue
public static final var MinValue : TimeSpan

Il valore del campo equivale a graduazioni Int64.MinValue. La rappresentazione in forma di stringa di questo valore è 10675199,02:48:05,4775808 negativo.

Nell'esempio di codice riportato di seguito si fa riferimento e si visualizza il valore del campo MinValue.

    // contain milliseconds.
