WriteXml Method (Stream, XmlWriteMode)

DataSet.WriteXml Method (Stream, XmlWriteMode)


Writes the current data, and optionally the schema, for the DataSet using the specified System.IO.Stream and XmlWriteMode. To write the schema, set the value for the mode parameter to WriteSchema.

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

public void WriteXml(
	Stream stream,
	XmlWriteMode mode


Type: System.IO.Stream

A Stream object used to write to a file.

Type: System.Data.XmlWriteMode

One of the XmlWriteMode values.

The WriteXml method provides a way to write either data only, or both data and schema from a DataSet into an XML document, whereas the WriteXmlSchema method writes only the schema. To write both data and schema, set the mode parameter 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 DataSet, use the ReadXml method. To read just the schema, use the ReadXmlSchema method.


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.
