c# - valor - ¿Cómo convierto un TimeSpan a una cadena formateada?

timespan c# ejemplos

Question

Esta pregunta ya tiene una respuesta aquí:

• ¿Cómo puedo String.Format un objeto TimeSpan con un formato personalizado en .NET? 18 respuestas
• Formato del tiempo [duplicado] 5 respuestas

Tengo dos DateTime vars, beginTime y endTime. He obtenido la diferencia de ellos haciendo lo siguiente:

TimeSpan dateDifference = endTime.Subtract(beginTime);

¿Cómo puedo ahora devolver una cadena de esto en formato hh hrs, mm mins, ss secs usando C #.

Si la diferencia fue 00: 06: 32.4458750

Debería devolver este 00 horas, 06 minutos, 32 segundos

Answer 1

¿ TimeSpan.ToString() haría el truco para usted? Si no, parece que el ejemplo de código en esa página describe cómo hacer un formateo personalizado de un objeto TimeSpan .

Answer 2

Acabo de construir algunos métodos de extensión TimeSpan. Pensé que podría compartir:

public static string ToReadableAgeString(this TimeSpan span)
{
    return string.Format("{0:0}", span.Days / 365.25);
}

public static string ToReadableString(this TimeSpan span)
{
    string formatted = string.Format("{0}{1}{2}{3}",
        span.Duration().Days > 0 ? string.Format("{0:0} day{1}, ", span.Days, span.Days == 1 ? String.Empty : "s") : string.Empty,
        span.Duration().Hours > 0 ? string.Format("{0:0} hour{1}, ", span.Hours, span.Hours == 1 ? String.Empty : "s") : string.Empty,
        span.Duration().Minutes > 0 ? string.Format("{0:0} minute{1}, ", span.Minutes, span.Minutes == 1 ? String.Empty : "s") : string.Empty,
        span.Duration().Seconds > 0 ? string.Format("{0:0} second{1}", span.Seconds, span.Seconds == 1 ? String.Empty : "s") : string.Empty);

    if (formatted.EndsWith(", ")) formatted = formatted.Substring(0, formatted.Length - 2);

    if (string.IsNullOrEmpty(formatted)) formatted = "0 seconds";

    return formatted;
}

Answer 3

Al convertirlo a una fecha y hora, puede obtener formatos localizados:

new DateTime(timeSpan.Ticks).ToString("HH:mm");

Answer 4

De acuerdo con la documentación de Microsoft , la estructura TimeSpan expone horas, minutos, segundos y milisegundos como miembros enteros. Tal vez quieras algo como:

dateDifference.Hours.ToString() + " hrs, " + dateDifference.Minutes.ToString() + " mins, " + dateDifference.Seconds.ToString() + " secs"

Answer 5

Esta es la solución más corta.

timeSpan.ToString(@"hh/:mm");

Answer 6

Gracias a Peter por el método de extensión. Lo modifiqué para que funcione mejor por períodos de tiempo más largos:

namespace ExtensionMethods
{
    public static class TimeSpanExtensionMethods
    {
        public static string ToReadableString(this TimeSpan span)
        {
            string formatted = string.Format("{0}{1}{2}",
                (span.Days / 7) > 0 ? string.Format("{0:0} weeks, ", span.Days / 7) : string.Empty,
                span.Days % 7 > 0 ? string.Format("{0:0} days, ", span.Days % 7) : string.Empty,
                span.Hours > 0 ? string.Format("{0:0} hours, ", span.Hours) : string.Empty);

            if (formatted.EndsWith(", ")) formatted = formatted.Substring(0, formatted.Length - 2);

            return formatted;
        }
    }
}

Answer 7

La forma más fácil de formatear un TimeSpan es agregarlo a un DateTime y formatear eso:

string formatted = (DateTime.Today + dateDifference).ToString("HH ''hrs'' mm ''mins'' ss ''secs''");

Esto funciona siempre que la diferencia de tiempo no sea más de 24 horas.

La propiedad Today devuelve un valor de DateTime donde el componente de tiempo es cero, por lo que el componente de tiempo del resultado es el valor de TimeSpan .

Answer 8

Puedes usar el siguiente código.

public static class TimeSpanExtensions
{
  public static String Verbose(this TimeSpan timeSpan)
  {
    var hours = timeSpan.Hours;
    var minutes = timeSpan.Minutes;

    if (hours > 0) return String.Format("{0} hours {1} minutes", hours, minutes);
    return String.Format("{0} minutes", minutes);
  }
}

Answer 9

Sé que esta es una respuesta tardía, pero esto funciona para mí:

TimeSpan dateDifference = new TimeSpan(0,0,0, (int)endTime.Subtract(beginTime).TotalSeconds); 

dateDifference ahora debe excluir las partes más pequeñas que un segundo. Funciona en .NET 2.0 también.

Answer 10

Sé que esta pregunta es anterior, pero .Net 4 ahora es compatible con los formatos TimeSpan personalizados .

También sé que se ha mencionado pero me sorprendió, convirtiendo Ticks en DateTime pero no maneja adecuadamente más de 24 horas.

new DateTime((DateTime.Now - DateTime.Now.AddHours(-25)).Ticks).ToString("HH:mm")

Eso te conseguirá 01:00 a 25:00 como es de esperar.

Answer 11

También tuve un problema similar y creé mi propia extensión, pero parece ser un poco diferente a todo lo demás.

    public static string TimeSpanToString(this TimeSpan timeSpan)
    {
        //if it''s negative
        if (timeSpan.Ticks < 0)
        {
            timeSpan = timeSpan - timeSpan - timeSpan;
            if (timeSpan.Days != 0)
                return string.Format("-{0}:{1}", timeSpan.Days.ToString("d"), new DateTime(timeSpan.Ticks).ToString("HH:mm:ss"));
            else
                return new DateTime(timeSpan.Ticks).ToString("-HH:mm:ss");
        }

        //if it has days
        else if (timeSpan.Days != 0)
            return string.Format("{0}:{1}", timeSpan.Days.ToString("d"), new DateTime(timeSpan.Ticks).ToString("HH:mm:ss"));

        //otherwise return the time
        else
            return new DateTime(timeSpan.Ticks).ToString("HH:mm:ss");
    }

Answer 12

Use String.Format () con múltiples parámetros.

using System;

namespace TimeSpanFormat
{
    class Program
    {
        static void Main(string[] args)
        {
            TimeSpan dateDifference = new TimeSpan(0, 0, 6, 32, 445);
            string formattedTimeSpan = string.Format("{0:D2} hrs, {1:D2} mins, {2:D2} secs", dateDifference.Hours, dateDifference.Minutes, dateDifference.Seconds);
            Console.WriteLine(formattedTimeSpan);
        }
    }
}

Answer 13

      public static string ToReadableString(this TimeSpan span)

         if (seconds == 1)
            return "1 second";

         return string.Format("{0:0} seconds", seconds);
      }
   }
