Question

我在时间Span类别中有一个小问题,在那里,时间Span可以划分23:59,但不是24。

当然,客户希望进入24小时,以显示当天的结束,而不是23:59或00:00,即:00:00,即当天的开始。

目前,我的法典规定最终时间为:

if ( !TimeSpan.TryParse( ( gvr.FindControl( "txtTimeOff" ) as TextBox ).Text, out tsTimeOff ) )
{
   this.ShowValidationError( String.Format( "Please enter a valid  Time Off  on row  {0} .", gvr.RowIndex + 1 ) );
   return false;
}

围绕这种情况的最佳工作是什么?

EDIT: (Solution 1)

if ( ( gvr.FindControl( "txtTimeOff" ) as TextBox ).Text == "24:00" )
{
    tsTimeOff = new TimeSpan( 24, 0, 0 );
}
else
{
    if ( !TimeSpan.TryParse( ( gvr.FindControl( "txtTimeOff" ) as TextBox ).Text, out tsTimeOff ) )
    {
         this.ShowValidationError(
            String.Format( "Please enter a valid  Time Off  on row  {0} .", gvr.RowIndex + 1 ) );
         return false;
    }
}

EDIT: (solution2)

string timeOff = ( gvr.FindControl( "txtTimeOff" ) as TextBox ).Text;

if ( !TimeSpan.TryParse(
        timeOff == "24:00" ? "1.00:00:00" : timeOff
        , out tsTimeOff ) )
{
    this.ShowValidationError(
        String.Format( "Please enter a valid  Time Off  on row  {0} .", gvr.RowIndex + 1 ) );
    return false;
}

Answer 1

试图这样做

textBox = (TextBox) gvr.FindControl ("txtTimeOff");

TimeSpan.TryParse (textBox.Text == "24:00"
                      ? "1.00:00"
                      : textBox.Text,
                   out tsTimeOff)

该法典可帮助您:

string span = "35:15";
TimeSpan ts = new TimeSpan(int.Parse(span.Split( : )[0]),    // hours
                           int.Parse(span.Split( : )[1]),    // minutes
                           0);                               // seconds

Generally the System.TimeSpan class is not well suited to represent a "point in time" but rather, as the name suggests, a "span" of time or duration. If you can refactor your code to use System.DateTime, or better yet System.DateTimeOffset, that would be the best solution. If that s not possible the other answer from Yahia is your best bet :)

最好的解决办法是通知客户,244小时不是有效小时,他应当使用0:00。我从未见过从23:59跳跃到24。
