WP7日期格式綁定

Question

期間我嘗試下面的下面的例子中，沒有運氣：

http://msdn.microsoft.com/en-us/library/system.windows.data.ivalueconverter%28v=VS.95%29.aspx

我也試圖跟着這個問題，以及：

Formatting a date in XAML on WP7

我不能讓它工作。當我嘗試添加引用，如：

<namespace:dateTimeConverter x:Key="MyDateTimeToStringConverter"/> 

或

<src:DateConverter x:Key="dateConverter"/> 

我不知道我在做什麼錯。任何幫助表示讚賞！

這裏是我的類代碼：

using System; 
using System.Net; 
using System.Windows; 
using System.Windows.Controls; 
using System.Windows.Documents; 
using System.Windows.Ink; 
using System.Windows.Input; 
using System.Windows.Media; 
using System.Windows.Media.Animation; 
using System.Windows.Shapes; 
using System.Windows.Data; 
using System.Globalization; 

namespace OilChangeApplication 
{ 

    public class dateTimeConverter : IValueConverter 
    { 
     public object Convert(object value, Type targetType, object parameter, CultureInfo culture) 
     { 
      DateTime date = (DateTime)value; 
      return date.ToShortDateString(); 
     } 

     public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) 
     { 
      string strValue = value as string; 
      DateTime resultDateTime; 
      if (DateTime.TryParse(strValue, out resultDateTime)) 
      { 
       return resultDateTime; 
      } 
      return DependencyProperty.UnsetValue; 
     } 
    } 

} 

這是我的Windows Phone形式XAML：

我也有一點麻煩，轉換器，發現了一個簡單的工作around是在你綁定的類上有另一個屬性，這些屬性被稱爲DisplayDate的行。

例如，如果您具有約束力OilChangedDate你可以將此屬性添加到您綁定類：

public string OilChangedDisplayDate 
{ 
    get { return OilChangedDate.ToShortDateString(); } 
} 

則此屬性，而不是直接的日期進行綁定。
