时间跨度和"24:00" Asp.net MVC中的解析错误 [英] TimeSpan and "24:00" parse error in Asp.net MVC

问题描述

我的Web应用程序中有一个模式对话框，用户可以在其中输入00:00到24:00之间的时间范围.范围滑块用于选择此范围.

I have a modal dialog in my web application where users are able to enter a time range between 00:00 and 24:00. A range slider is used to select this range.

一切正常，所不同的是，只要用户将正确的范围手柄设置为24:00的值，默认模型联编程序就无法解析此TimeSpan.

Everything works as expected except that whenever user sets the right range handle to have a value of 24:00 default model binder can't parse this TimeSpan.

public class Timing
{
    public TimeSpan Starts { get; set; }
    public TimeSpan Ends { get; set; }
}

我发送回服务器的对象具有IList<Timing>属性.

My object that gets sent back to server has an IList<Timing> property.

所以.问题是不能将字符串值"24:00"解析为TimeSpan实例.是否可以说服默认模型联编程序识别此类字符串值?

So. The problem is just that string value "24:00" can't be parsed to TimeSpan instance. Is it possible to convince default model binder to recognise such string value?

我想避免将客户端的24:00更改为00:00.我知道我具有Starts和Ends属性，但是我的模型验证确认Ends总是大于Starts.手动更改为23:59也很麻烦. 基本上可以通过24:00并仍在服务器上进行解析.

I would like to avoid changing 24:00 on the client to 00:00. I know that I have Starts and Ends properties but my model validation validates that Ends is always greater than Starts. Manual changing to 23:59 is also cumbersome. Basically is it possible to pass 24:00 and still get parsed on the server.

推荐答案

我认为范围过小. 24:00实际上是第二天的00:00. 因此它们应该从00:00.00更改为23:59.99或其他任何内容.

I think the range is fractionally too large. 24:00 is in fact 00:00 the next day. so they should go from 00:00.00 to 23:59.99 or whatever.

最终答案(?)将客户端上的24:00更改为1.0:00. 这将起作用，因为TimeSpan.Parse("1.0:00").TotalHours返回24

FINAL ANSWER(?) Change 24:00 on the client to 1.0:00. This will work because TimeSpan.Parse("1.0:00").TotalHours returns 24

:请参阅此处的文档: http: //msdn.microsoft.com/zh-CN/library/se73z7b9.aspx .它显示了天，小时，分钟等的最大范围.根据我的以下评论，小时范围是0至23.

See the documentation here: http://msdn.microsoft.com/en-us/library/se73z7b9.aspx. It shows the maximum range for days, hours, mins, etc. For hours it's 0 to 23 as per my comment below.

如果只是让他们选择一个小时的整数，然后在服务器上解析它.

If you are just letting them choose an integer for hours, then parse it on the server.

例如TimeSpan ts = TimeSpan.FromHours(24) 返回1.00:00:00 当然，您总是可以说ts.TotalHours并且它返回24.

eg. TimeSpan ts = TimeSpan.FromHours(24) returns 1.00:00:00 And of course you can always say ts.TotalHours and it returns 24.
