Safor,
Я сделал именно то, что предложил Энтони для моего собственного заявления.
Вот ваш XAML, модифицированный для использования CustomUriMapper:
<nav:Frame Source="/Home">
<nav:Frame.UriMapper>
<app:CustomUriMapper>
<app:CustomUriMapping Uri="" MappedUri="/Views/HomePage.xaml"/>
<app:CustomUriMapping Uri="/entity/{code}" MappedUri="/Views/EntityEditorPage.xaml?code={code}"/>
<app:CustomUriMapping Uri="/{pageName}" MappedUri="/Views/{pageName}Page.xaml"/>
</app:CustomUriMapper>
</nav:Frame.UriMapper>
</nav:Frame>
Вот код для классов CustomUriMapping и CustomUriMapper:
using System;
using System.Collections.ObjectModel;
using System.Windows.Markup;
using System.Windows.Navigation;
namespace YourApplication
{
// In XAML:
// <app:CustomUriMapper>
// <app:CustomUriMapping Uri="/{search}" MappedUri="/Views/searchpage.xaml?searchfor={search}"/>
// </app:CustomUriMapper>
public class CustomUriMapping
{
public Uri Uri { get; set; }
public Uri MappedUri { get; set; }
public Uri MapUri(Uri uri)
{
// Do the uri mapping without regard to upper or lower case
UriMapping _uriMapping = new UriMapping() { Uri = (Uri == null || string.IsNullOrEmpty(Uri.OriginalString) ? null : new Uri(Uri.OriginalString.ToLower(), UriKind.RelativeOrAbsolute)), MappedUri = MappedUri };
return _uriMapping.MapUri(uri == null || string.IsNullOrEmpty(uri.OriginalString) ? null : new Uri(uri.OriginalString.ToLower(), UriKind.RelativeOrAbsolute));
}
}
[ContentProperty("UriMappings")]
public class CustomUriMapper : UriMapperBase
{
public ObservableCollection<CustomUriMapping> UriMappings { get { return m_UriMappings; } private set { m_UriMappings = value; } }
private ObservableCollection<CustomUriMapping> m_UriMappings = new ObservableCollection<CustomUriMapping>();
public override Uri MapUri(Uri uri)
{
if (m_UriMappings == null)
return uri;
foreach (CustomUriMapping mapping in m_UriMappings)
{
Uri mappedUri = mapping.MapUri(uri);
if (mappedUri != null)
return mappedUri;
}
return uri;
}
}
}
Удачи, Джим МакКарди
