DataTable.WriteXml Method (XmlWriter, XmlWriteMode, Boolean)
Assembly: System.Data (in system.data.dll)
public function WriteXml ( writer : XmlWriter, mode : XmlWriteMode, writeHierarchy : boolean )
The XmlWriter used to write the document.
One of the XmlWriteMode values.
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.
The WriteXml method provides a way to write either data only, or both data and schema from a DataTable into an XML document, whereas the WriteXmlSchema method writes only the schema. To write both data and schema, use one of the overloads that include the XmlWriteMode parameter, and set its value to WriteSchema.
Note that the same is true for the ReadXml and ReadXmlSchema methods, respectively. To read XML data, or both schema and data into the DataTable, use the ReadXml method. To read just the schema, use the ReadXmlSchema method.
Normally the WriteXml method writes the data only for the current table. To write the data for the current table and its entire descendant, related tables, call the method with the writeHierarchy parameter set to true.
