Esempio

Usare gli System.Drawingspazi dei nomi , System.Drawing.Printinge System.IO per questo esempio.

Nell'esempio di codice seguente vengono impostate le impostazioni di pagina predefinite per un documento sui margini di 1 pollice su ogni lato.

void Printing()

              has been set to the path of the file to print. */

Commenti

La Margins classe viene usata per modificare la larghezza dei margini in PageSettings e PrintController. MarginsConverter è il descrittore di tipo per questa classe.

Left, Right, Tope Bottom sono proprietà che definiscono i margini. Clone crea un oggetto identico Margins. Equals determina se un altro oggetto ha le stesse dimensioni di un Marginsoggetto .
