DataTable.WriteXml Method (TextWriter)
Assembly: System.Data (in System.Data.dll)
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.
