DataTable::WriteXml Method (String^, XmlWriteMode)

 

Writes the current data, and optionally the schema, for the DataTable using the specified file 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(
	String^ fileName,
	XmlWriteMode mode
)

Parameters

fileName
Type: System::String^

The name of the file to which the data will be written.

mode
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 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.

System_CAPS_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.
