  • Use the Path property to specify the source value you want to bind to:
    • In the simplest case, the Path property value is the name of the property of the source object to use for the binding, such as Path=PropertyName.
    • Subproperties of a property can be specified by a syntax similar to that used in C#. For instance, the clause Path=ShoppingCart.Order sets the binding to the subproperty Order of the object or property ShoppingCart.
    • To bind to an attached property, place parentheses around the attached property. For example, to bind to the attached property DockPanel.Dock, the syntax isPath=(DockPanel.Dock).
    • Indexers of a property can be specified within square brackets following the property name where the indexer is applied. For instance, the clause Path=ShoppingCart[0] sets the binding to the index that corresponds to how your property's internal indexing handles the literal string "0". Multiple indexers are also supported.
    • Indexers and subproperties can be mixed in a Path clause; for example, Path=ShoppingCart.ShippingInfo[MailingAddress,Street].
    • Inside indexers you can have multiple indexer parameters separated by commas (,). The type of each parameter can be specified with parentheses. For example, you can have Path="[(sys:Int32)42,(sys:Int32)24]", where sys is mapped to the System namespace.
    • When the source is a collection view, the current item can be specified with a slash (/). For example, the clause Path=/ sets the binding to the current item in the view.
    • When the source is a collection, this syntax specifies the current item of the default collection view.
    • Property names and slashes can be combined to traverse properties that are collections. For example, Path=/Offices/ManagerName specifies the current item of the source collection, which contains an Offices property that is also a collection. Its current item is an object that contains a ManagerName property. Optionally, a period (.) path can be used to bind to the current source. For example, Text="{Binding}" is equivalent to Text="{Binding Path=.}".


补充一下,WP8开发中,app bar的icon,要求很龌龊:透明、alpha、白色前景。




public static BitmapImage GetBitmapFromIsolatedFolderByName(string file)
            BitmapImage image = new BitmapImage();
            var stream = localFolder.OpenFile(cachePath+"\\"+file, System.IO.FileMode.Open);

            return image;


 重点在于红色那一行,如果不close,那么第二次就会发生这个exception。令人发指的是,发生exception的时候,callstack都是reflection的东西,看不到真正的root cause。
