DataTable.WriteXml Method (Stream, Boolean)


Writes the current contents of the DataTable as XML using the specified Stream. To save the data for the table and all its descendants, set the writeHierarchy parameter to true.

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

public void WriteXml(
	Stream stream,
	bool writeHierarchy


Type: System.IO.Stream

The stream to which the data will be written.

Type: System.Boolean

If true, write the contents of the current table and all its descendants. If false (the default value), write the data for the current table only.

Use the WriteXmlSchema method to write the schema for a DataTable to an XML document. The schema includes table, relation, and constraint definitions.

The XML schema is written using the XSD standard.

To write the data to an XML document, use the WriteXml method.

Normally the WriteXml method writes the data only for the current table. To write the data for the current table and all of its descendant, related tables, call the method with the writeHierarchy parameter set to true.


An InvalidOperationException will be thrown if a column type in the DataRow being read from or written to implements IDynamicMetaObjectProvider and does not implement IXmlSerializable.
