XamlXmlWriter.WriteStartMember Method

Writes a XAML start member node to the underlying XmlWriter or TextWriter. Throws an exception if the current position of the XAML node stream is within another member, or if it is not in a scope or writer state where a start member can be written.

Namespace:  System.Xaml
Assembly:  System.Xaml (in System.Xaml.dll)

public override void WriteStartMember(
	XamlMember property


Type: System.Xaml.XamlMember

The XAML member identifier for the member to write.


property is null.


property is not a valid XamlMember.


The current position of the XAML node stream is invalid for writing a start member.


The writer state is not valid for writing a start member.


The XAML writer attempted to write a duplicate member. This exception may have a more precise inner exception.

Internal default logic in the XamlXmlWriter first attempts to write the member in attribute form. If no attribute form is supported because the property or its value does not support text syntax, a property element is written instead. If the property is a XAML content property, a GetObject case, or an implicit property, other XAML forms might be written, such as inner text or an object child that has no intervening member.

The duplicate member exception is never thrown if AssumeValidInput is true in the XamlXmlWriterSettings object that was used for settings for this XamlXmlWriter.
