DataSet.WriteXml Method (Stream)

Writes the current data for the DataSet using the specified System.IO.Stream.

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

public void WriteXml (
	Stream stream
)
public void WriteXml (
	Stream stream
)
public function WriteXml (
	stream : Stream
)

Parameters

stream

A Stream object used to write to a file.

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.

The following example creates a System.IO.FileStream object. The object is then used with the WriteXml method to write an XML document.

private void WriteXmlToFile(DataSet thisDataSet) 
{
    if (thisDataSet == null) { return; 

    // Create a file name to write to.
    string filename = "XmlDoc.xml";

    // Create the FileStream to write with.
    System.IO.FileStream stream = new System.IO.FileStream
        (filename, System.IO.FileMode.Create);

    // Write to the file with the WriteXml method.
    thisDataSet.WriteXml(stream);
