XamlWriter.Save Method (Object)

Returns a XAML string that serializes the specified object and its properties.

Namespace:  System.Windows.Markup
Assembly:  PresentationFramework (in PresentationFramework.dll)

Public Shared Function Save ( _
	obj As Object _
) As String


Type: System.Object

The element to be serialized. Typically, this is the root element of a page or application.

Return Value

Type: System.String
A XAML string that can be written to a stream or file. The logical tree of all elements that fall under the provided obj element will be serialized.


obj is Nothing.


The application is not running in full trust.

The serialization enabled by this method has a series of limitations. This is because the serialization enabled is explicitly run-time, and does not have access to possible design-time information in the original XAML (if any). For details, see Serialization Limitations of XamlWriter.Save.

Calling Save is not permitted when running in partial trust.

The following example serializes a Button into a string using the XamlWriter class. The string is then deserialized back into a Button using the static Load method on the XamlReader class.

' Create the Button.
Dim originalButton As New Button()
originalButton.Height = 50
originalButton.Width = 100
originalButton.Background = Brushes.AliceBlue
originalButton.Content = "Click Me"

' Save the Button to a string.
Dim savedButton As String = XamlWriter.Save(originalButton)

' Load the button
Dim stringReader As New StringReader(savedButton)
Dim xmlReader As XmlReader = XmlReader.Create(stringReader)
Dim readerLoadButton As Button = CType(XamlReader.Load(xmlReader), Button)
