ASP.NET MVC3 - DateTime格式 [英] ASP.NET MVC3 - DateTime format

问题描述

我使用ASP.NET MVC 3结果
我的视图模型看起来是这样的：

I'm using ASP.NET MVC 3.
My ViewModel looks like this:

public class Foo
{
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd.MM.yyyy}", ApplyFormatInEditMode = true)]
    public DateTime StartDate { get; set; }
    ...
}

在看，我有这样的事情：

In view, I have something like this:

<div class="editor-field">
    @Html.EditorFor(model => model.StartDate)
    <br />
    @Html.ValidationMessageFor(model => model.StartDate)
</div>

开始日期显示为正确的格式，但是当我改变它的价值，2011年11月19日和提交表单，我收到以下错误信息：值'19 .11.2011'是无效的起始日期

StartDate is displayed in correct format, but when I change it's value to 19.11.2011 and submit the form, I get the following error message: "The value '19.11.2011' is not valid for StartDate."

任何帮助将大大AP preciated！

Any help would be greatly appreciated!

推荐答案

您需要设置正确的文化在你的web.config文件的全球化元素而 DD.MM.YYYY 是一个有效的日期时间格式：

You need to set the proper culture in the globalization element of your web.config file for which dd.MM.yyyy is a valid datetime format:

<globalization culture="...." uiCulture="...." />

例如这是默认的格式，在德国：去DE

For example that's the default format in german: de-DE.

更新：

根据你要保持应用程序的EN-US区域性，但仍使用不同格式的日期的评论部分您的要求。这可以通过编写自定义模型绑定来实现：

According to your requirement in the comments section you want to keep en-US culture of the application but still use a different formats for the dates. This could be achieved by writing a custom model binder:

public class MyDateTimeModelBinder : DefaultModelBinder
{
    public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
        var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);

        if (!string.IsNullOrEmpty(displayFormat) && value != null)
        {
            DateTime date;
            displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
            // use the format specified in the DisplayFormat attribute to parse the date
            if (DateTime.TryParseExact(value.AttemptedValue, displayFormat, CultureInfo.InvariantCulture, DateTimeStyles.None, out date))
            {
                return date;
            }
            else
            {
                bindingContext.ModelState.AddModelError(
                    bindingContext.ModelName, 
                    string.Format("{0} is an invalid date format", value.AttemptedValue)
                );
            }
        }

        return base.BindModel(controllerContext, bindingContext);
    }
}

您将在注册的Application_Start ：

ModelBinders.Binders.Add(typeof(DateTime), new MyDateTimeModelBinder());
