Ejemplos

En el ejemplo siguiente se crea un nuevo FileStream objeto que se pasa al WriteXmlSchema método para escribir el esquema en el disco.

private void WriteSchemaWithFileStream(DataSet thisDataSet)
{
    // Set the file path and name. Modify this for your purposes.
    string filename="Schema.xml";

    // Create the FileStream object with the file name.
    // Use FileMode.Create.
    System.IO.FileStream stream =
        new System.IO.FileStream(filename,System.IO.FileMode.Create);

    // Write the schema to the file.
    thisDataSet.WriteXmlSchema(stream);

    // Close the FileStream.
    stream.Close();
}

Private Sub WriteSchemaWithFileStream(thisDataSet As DataSet)
    ' Set the file path and name. Modify this for your purposes.
    Dim filename As String = "Schema.xml"

    ' Create the FileStream object with the file name. 
    ' Use FileMode.Create.
    Dim stream As New System.IO.FileStream _
        (filename, System.IO.FileMode.Create)

    ' Write the schema to the file.

Comentarios

Use el WriteXmlSchema método para escribir el esquema de en DataSet un documento XML. El esquema incluye definiciones de tabla, relación y restricción. Para escribir un esquema en un documento XML, use el WriteXmlSchema método .

El esquema XML se escribe mediante el estándar XSD.

Para escribir los datos en un documento XML, use el WriteXml método .

Las clases que derivan de la Stream clase incluyen BufferedStream, FileStream, MemoryStreamy NetworkStream.

Ejemplos

En el ejemplo siguiente se crea un System.Text.StringBuilder objeto en que se usa para crear un objeto .System.IO.StringWriter StringWriter se pasa al WriteXmlSchema método y la cadena resultante se imprime en la ventana de la consola.

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());
}

Private Sub WriteSchemaWithStringWriter(thisDataSet As DataSet)
    ' Create a new StringBuilder object.
    Dim builder As New System.Text.StringBuilder()

    ' Create the StringWriter object with the StringBuilder object.
