我在将短日期格式绑定到DateTime模型属性时遇到了同样的问题。在查看了许多不同的示例（不仅涉及DateTime）之后，我整理了以下内容：
using System;
using System.Globalization;
using System.Web.Mvc;
namespace YourNamespaceHere
{
public class CustomDateBinder : IModelBinder
{
public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
if (controllerContext == null)
throw new ArgumentNullException("controllerContext", "controllerContext is null.");
if (bindingContext == null)
throw new ArgumentNullException("bindingContext", "bindingContext is null.");
var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
if (value == null)
throw new ArgumentNullException(bindingContext.ModelName);
CultureInfo cultureInf = (CultureInfo)CultureInfo.CurrentCulture.Clone();
cultureInf.DateTimeFormat.ShortDatePattern = "dd/MM/yyyy";
bindingContext.ModelState.SetModelValue(bindingContext.ModelName, value);
try
{
var date = value.ConvertTo(typeof(DateTime), cultureInf);
return date;
}
catch (Exception ex)
{
bindingContext.ModelState.AddModelError(bindingContext.ModelName, ex);
return null;
}
}
}
public class NullableCustomDateBinder : IModelBinder
{
public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
if (controllerContext == null)
throw new ArgumentNullException("controllerContext", "controllerContext is null.");
if (bindingContext == null)
throw new ArgumentNullException("bindingContext", "bindingContext is null.");
var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
if (value == null) return null;
CultureInfo cultureInf = (CultureInfo)CultureInfo.CurrentCulture.Clone();
cultureInf.DateTimeFormat.ShortDatePattern = "dd/MM/yyyy";
bindingContext.ModelState.SetModelValue(bindingContext.ModelName, value);
try
{
var date = value.ConvertTo(typeof(DateTime), cultureInf);
return date;
}
catch (Exception ex)
{
bindingContext.ModelState.AddModelError(bindingContext.ModelName, ex);
return null;
}
}
}
}
为了保持在Global ASAX文件中重新注册路由等的方式，我还向名为CustomModelBinderConfig的MVC4项目的App_Start文件夹中添加了一个新的语法类：
using System;
using System.Web.Mvc;
namespace YourNamespaceHere
{
public static class CustomModelBindersConfig
{
public static void RegisterCustomModelBinders()
{
ModelBinders.Binders.Add(typeof(DateTime), new CustomModelBinders.CustomDateBinder());
ModelBinders.Binders.Add(typeof(DateTime?), new CustomModelBinders.NullableCustomDateBinder());
}
}
}
然后，我仅从全局ASASX Application_Start调用静态RegisterCustomModelBinders，如下所示：
protected void Application_Start()
{
/* bla blah bla the usual stuff and then */
CustomModelBindersConfig.RegisterCustomModelBinders();
}
这里的重要说明是，如果您将DateTime值写入这样的hiddenfield：
@Html.HiddenFor(model => model.SomeDate) // a DateTime property
@Html.Hiddenfor(model => model) // a model that is of type DateTime
我这样做了，页面上的实际值的格式为“ MM / dd / yyyy hh：mm：ss tt”，而不是我想要的“ dd / MM / yyyy hh：mm：ss tt”。这导致我的模型验证失败或返回错误的日期（显然交换了日期和月份值）。
经过大量的尝试和失败的尝试之后，解决方案是通过在Global.ASAX中执行以下操作来设置每个请求的区域性信息：
protected void Application_BeginRequest()
{
CultureInfo cInf = new CultureInfo("en-ZA", false);
// NOTE: change the culture name en-ZA to whatever culture suits your needs
cInf.DateTimeFormat.DateSeparator = "/";
cInf.DateTimeFormat.ShortDatePattern = "dd/MM/yyyy";
cInf.DateTimeFormat.LongDatePattern = "dd/MM/yyyy hh:mm:ss tt";
System.Threading.Thread.CurrentThread.CurrentCulture = cInf;
System.Threading.Thread.CurrentThread.CurrentUICulture = cInf;
}
如果将其粘贴在Application_Start或Session_Start中，它将无法工作，因为它将其分配给会话的当前线程。众所周知，Web应用程序是无状态的，因此以前为您的请求提供服务的线程与为您当前的请求提供服务的线程是同一线程，因此您的区域性信息已经进入了数字天空的宏伟GC。
