DataTable.WriteXml Method (String, Boolean)

Writes the current contents of the DataTable as XML using the specified file. 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(
	string fileName,
	bool writeHierarchy
)

Parameters

fileName
Type: System.String

The file to which to write the XML data.

writeHierarchy
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.

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 includes 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 all of its descendant, related tables, call the method with the writeHierarchy parameter set to true.
