DataSet.WriteXml Method (TextWriter)

Writes the current data for the DataSet using the specified TextWriter.

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

member WriteXml : 
        writer:TextWriter -> unit

Parameters

writer
Type: System.IO.TextWriter

The TextWriter object with which to write.

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, use one of the overloads that includes the mode 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 DataSet, use the ReadXml method. To read just the schema, use the ReadXmlSchema method.

NoteNote

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.
