Asp.net mvc5日期时间渲染格式 [英] Asp.net mvc5 datetime rendering format

问题描述

这是模型：
 
 e [DataType（DataType.Date）] 
 
 public Nullable< System.DateTime> PublishDate {get;组; } 
这是视图：
 
 e< dt> 
 @ Html.DisplayNameFor（model => model.PublishDate）
< / dt> 
 
< dd> 
 @ Html.DisplayFor（model => model.PublishDate）
< / dd> 
当我使用该页面的英文版本时，日期以这种方式呈现，例如2017年8月14日，当我用法语更改语言时，日期以这种方式呈现14.8.2017。为什么它很开心，任何人都可以帮助我，因为无论选择哪种语言，日期格式都应该是一样的。

< b>我尝试了什么：



i解释了上面的问题和我的解决方案。

解决方案

< blockquote>在追逐文化时试试这个。将newCulture设置为您改变的文化

 CultureInfo newCulture =（CultureInfo）System.Threading.Thread.CurrentThread.CurrentCulture.Clone（）; 
 newCulture.DateTimeFormat.ShortDatePattern =dd-MMM-yyyy; 
 newCulture.DateTimeFormat.DateSeparator = - ; 
 Thread.CurrentThread.CurrentCulture = newCulture; 
 

替换为此代码

 protected void Application_AcquireRequestState（object sender，EventArgs e）
 { 
 //检查会话对象是否准备就绪很重要
 if（HttpContext.Current.Session！= null）
 {
 CultureInfo ci =（CultureInfo）this.Session [ Culturee]; 
 //首先检查会话中是否没有值
 //并设置默认语言
 //这可能发生在第一个用户的请求
 if（ci == null）
 {
 //将默认文化设置为英语不变量
 string langName =en; 
 
 //尝试从Accept lang HTTP头获取值
 if（HttpContext.Current.Request.UserLanguages！= null&& 
 HttpContext.Current.Request.UserLanguages .Length！= 0）
 {
 //获取接受列表
 langName = HttpContext.Current.Request.UserLanguages [0] .Substring（0,2）; 
} 
 ci = new CultureInfo（langName）; 
 this.Session [Culturee] = ci; 
} 
 //最后为每个请求设置文化
 
 ci.DateTimeFormat.ShortDatePattern =dd-MMM-yyyy; 
 ci.DateTimeFormat.DateSeparator = - ; 
 Thread.CurrentThread.CurrentUICulture = ci; 
 Thread.CurrentThread.CurrentCulture = ci; 
 
 //Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture（ci.Name）; 
 
 
 
} 
} 

如果要控制特定格式字段，使用 DisplayFormat 属性：

DisplayFormatAttribute类| Microsoft Docs [ ^ ]

 [DisplayFormat（  dd-MMM-yyyy）] 
  public  DateTime？ PublishDate { get ;  set ; } 

（ NB： DateTime？是编写 Nullable< DateTime> <的简写方式/ code>。）



如果要覆盖所有日期的格式，请在 Views \Shared中创建显示模板\ DisplayTemplates\Date.cshtml ：



 @model DateTime？ 
 @if（Model.HasValue）
 {
 @ Model.Value.ToString（dd-MMM-yyyy）
} 

然后添加任何应该只显示日期的属性的 DataType 属性：



 [DataType（DataType.Date）] 
  public  DateTime？ PublishDate { get ;  set ; } 





如果要关闭整个应用程序的自动全球化，可以更改 web.config 文件。您可能将文化设置为自动：



< configuration> 
< system.web> 
< globalization culture =autouiCulture =auto/> 
< /system.web> 
< / configuration> 

这会根据用户的首选语言设置文化。



将auto替换为代码您想要使用的文化。例如：



< configuration> 
< system.web> 
< globalization culture =en-GBuiCulture =en-GB/> 
< /system.web> 
< / configuration> 



您甚至可以为文化和UI文化设置不同的设置 - 文化驱动数字和日期格式，货币符号，排序等UI文化主要用于确定哪些 .resx 文件用于查找本地化资源。

This is the model :

e[DataType(DataType.Date)]

    public Nullable<System.DateTime> PublishDate { get; set; }
This is the view :

e   <dt>
            @Html.DisplayNameFor(model => model.PublishDate)
        </dt>

        <dd>
            @Html.DisplayFor(model => model.PublishDate)
        </dd>
When I am on English version of the page , date renders in this way for example 14/08/2017 , and when i change language in French then date renders in this way 14.8.2017 . Why it is happining that , can anyone help me , for no matter language selected , the date format should always be the same .



What I have tried:

i explained the problem and my solution above.

解决方案

Try this while chaging the culture. Set newCulture as your changed culture

CultureInfo newCulture = (CultureInfo)System.Threading.Thread.CurrentThread.CurrentCulture.Clone();
newCulture.DateTimeFormat.ShortDatePattern = "dd-MMM-yyyy";
newCulture.DateTimeFormat.DateSeparator = "-";
Thread.CurrentThread.CurrentCulture = newCulture;

Replace with this code

protected void Application_AcquireRequestState(object sender, EventArgs e)
{
//It's important to check whether session object is ready
if (HttpContext.Current.Session != null)
{
CultureInfo ci = (CultureInfo)this.Session["Culturee"];
//Checking first if there is no value in session 
//and set default language 
//this can happen for first user's request
if (ci == null)
{
//Sets default culture to english invariant
string langName = "en";

//Try to get values from Accept lang HTTP header
if (HttpContext.Current.Request.UserLanguages != null && 
HttpContext.Current.Request.UserLanguages.Length != 0)
{
//Gets accepted list 
langName = HttpContext.Current.Request.UserLanguages[0].Substring(0, 2);
}
ci = new CultureInfo(langName);
this.Session["Culturee"] = ci;
}
//Finally setting culture for each request

ci.DateTimeFormat.ShortDatePattern = "dd-MMM-yyyy";
ci.DateTimeFormat.DateSeparator = "-";
Thread.CurrentThread.CurrentUICulture = ci;
Thread.CurrentThread.CurrentCulture = ci;

//Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(ci.Name);


  
}
}




If you want to control the format for a specific field, use the DisplayFormat attribute:
DisplayFormatAttribute Class | Microsoft Docs[^]

[DisplayFormat("dd-MMM-yyyy")]
public DateTime? PublishDate { get; set; }

(NB: DateTime? is a shorthand way of writing Nullable<DateTime>.)

If you want to override the format for all dates, create a display template in Views\Shared\DisplayTemplates\Date.cshtml:

@model DateTime?
@if (Model.HasValue)
{
    @Model.Value.ToString("dd-MMM-yyyy")
}

and then add the DataType attribute to any properties which should only show the date:

[DataType(DataType.Date)]
public DateTime? PublishDate { get; set; }

If you want to turn off automatic globalization for the entire application, you can change the web.config file. You probably have the culture set to "auto":

<configuration>
  <system.web>
    <globalization culture="auto" uiCulture="auto" />
  </system.web>
</configuration>

This sets the culture based on the user's preferred language.

Replace "auto" with the code of the culture you want to use. For example:

<configuration>
  <system.web>
    <globalization culture="en-GB" uiCulture="en-GB" />
  </system.web>
</configuration>

You can even have different settings for culture and UI culture - the culture drives number and date formatting, currency symbols, sorting, etc., whereas the UI culture is primarily used to determine which .resx files are used to look up localized resources.
