Silverlight内存泄漏 [英] silverlight memory leak

问题描述

我正在使用以下代码创建通过回调方法更改的DependencyProperty:

i was creating a DependencyProperty Changed with a callback method using the following code:

public void RegisterForNotification(string propertyName, FrameworkElement element, PropertyChangedCallback callback) 
        { 
 
            Binding b = new Binding(propertyName) { Source = element }; 
            var prop = System.Windows.DependencyProperty.RegisterAttached( 
                "ListenAttached" + propertyName, 
                typeof(object), 
                typeof(UserControl), 
                new System.Windows.PropertyMetadata(callback));              
            element.SetBinding(prop, b); 
        }

回调方法导致应用程序内存泄漏，如何注销该回调方法?

The callback method caused a memory leak in my application, how can i unregister this callback method?

thanks in advance.
