Timespan formatting [duplicate]

Answer 1

public static string GetDurationInWords( TimeSpan aTimeSpan )
{
    string timeTaken = string.Empty;

    if( aTimeSpan.Days > 0 )
        timeTaken += aTimeSpan.Days + " day" + ( aTimeSpan.Days > 1 ? "s" : "" );

    if( aTimeSpan.Hours > 0 )
    {
        if( !string.IsNullOrEmpty( timeTaken ) )
           timeTaken += " ";
        timeTaken += aTimeSpan.Hours + " hour" + ( aTimeSpan.Hours > 1 ? "s" : "" );
    }

    if( aTimeSpan.Minutes > 0 )
    {
       if( !string.IsNullOrEmpty( timeTaken ) )
           timeTaken += " ";
       timeTaken += aTimeSpan.Minutes + " minute" + ( aTimeSpan.Minutes > 1 ? "s" : "" );
    }

    if( aTimeSpan.Seconds > 0 )
    {
       if( !string.IsNullOrEmpty( timeTaken ) )
           timeTaken += " ";
       timeTaken += aTimeSpan.Seconds + " second" + ( aTimeSpan.Seconds > 1 ? "s" : "" );
    }

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

     return timeTaken;
}
