Parameters

writer

The TextWriter object with which to write.

Use the WriteXmlSchema method to write the schema for a DataSet to an XML document. The schema includes table, relation, and constraint definitions. To write a schema to an XML document, use the WriteXmlSchema method.

The XML schema is written using the XSD standard.

To write the data to an XML document, use the WriteXml method.

Classes the derive from the System.IO.TextWriter class include the System.Web.HttpWriter, System.CodeDOM.Compiler.IndentedTextWriter, System.Web.UI.HtmlTextWriter, System.IO.StreamWriter, and System.IO.StringWriter.

The following example creates a System.Text.StringBuilder object to that is used to create a new System.IO.StringWriter. The StringWriter is passed to the WriteXmlSchema method, and the resulting string is printed to the console window.

private void WriteSchemaWithStringWriter(DataSet thisDataSet)
{
    // Create a new StringBuilder object.
    System.Text.StringBuilder builder = new System.Text.StringBuilder();

    // Create the StringWriter object with the StringBuilder object.
    System.IO.StringWriter writer = new System.IO.StringWriter(builder);

    // Write the schema into the StringWriter.
    thisDataSet.WriteXmlSchema(writer);

    // Print the string to the console window.
    Console.WriteLine(writer.ToString());
