範例

下列程式碼範例會在預設印表機上列印名為 C:\My Documents\MyFile.txt 的檔案。The following code example prints the file named C:\My Documents\MyFile.txt on the default printer. 若要執行範例,請建立新的 Windows Forms 專案,並將範例程式碼貼入表單中,並取代檔案內容。To run the example, create a new Windows Forms project and paste the example code into the form, replacing the file contents. 若C#為,您必須刪除 Form1.Designer.cs 檔案。For C#, you will need to delete the Form1.Designer.cs file. 此外,也請變更您要列印之檔案的路徑。Also, change the path to the file you want to print.

注意

此範例要求每一行都符合頁面寬度。The example requires that each line fits within the page width.

備註

通常,您會建立 PrintDocument 類別的實例、設定 DocumentNamePrinterSettings等屬性,並呼叫 Print 方法來啟動列印程式。Typically, you create an instance of the PrintDocument class, set properties such as the DocumentName and PrinterSettings, and call the Print method to start the printing process. 使用 PrintPageEventArgsGraphicsGraphics 屬性,處理您指定要列印之輸出的 PrintPage 事件。Handle the PrintPage event where you specify the output to print, by using the GraphicsGraphics property of the PrintPageEventArgs.

如需從 Windows Form 應用程式列印的詳細資訊,請參閱Windows Forms 列印支援For more information about printing from a Windows Form application, see the Windows Forms Print Support. 如果您想要從 Windows Presentation Foundation 應用程式進行列印,請參閱 System.Printing 命名空間。If you wish to print from a Windows Presentation Foundation application, see the System.Printing namespace.
