示例

下面的代码示例演示 的 Document、 UseAntiAlias和 Zoom 属性 PrintPreviewControl。 若要运行此示例，请将以下代码放在窗体中，然后从窗体的构造函数或Load事件处理方法调用 InitializePrintPreviewControl 方法。

C#

// Declare the PrintPreviewControl object and the 
// PrintDocument object.
internal PrintPreviewControl PrintPreviewControl1;
private System.Drawing.Printing.PrintDocument docToPrint = 
    new System.Drawing.Printing.PrintDocument();

private void InitializePrintPreviewControl()
{

    // Construct the PrintPreviewControl.
    this.PrintPreviewControl1 = new PrintPreviewControl();

    // Set location, name, and dock style for PrintPreviewControl1.
    this.PrintPreviewControl1.Location = new Point(88, 80);
    this.PrintPreviewControl1.Name = "PrintPreviewControl1";
    this.PrintPreviewControl1.Dock = DockStyle.Fill;

    // Set the Document property to the PrintDocument 
    // for which the PrintPage event has been handled.
    this.PrintPreviewControl1.Document = docToPrint;

    // Set the zoom to 25 percent.
    this.PrintPreviewControl1.Zoom = 0.25;

    // Set the document name. This will show be displayed when 
    // the document is loading into the control.
    this.PrintPreviewControl1.Document.DocumentName = "c:\\someFile";

    // Set the UseAntiAlias property to true so fonts are smoothed
    // by the operating system.
    this.PrintPreviewControl1.UseAntiAlias = true;

    // Add the control to the form.
    this.Controls.Add(this.PrintPreviewControl1);
    
    // Associate the event-handling method with the
    // document's PrintPage event.
    this.docToPrint.PrintPage += 
        new System.Drawing.Printing.PrintPageEventHandler(
        docToPrint_PrintPage);
}

// The PrintPreviewControl will display the document
// by handling the documents PrintPage event
private void docToPrint_PrintPage(
    object sender, System.Drawing.Printing.PrintPageEventArgs e)
{

    // Insert code to render the page here.
    // This code will be called when the control is drawn.

    // The following code will render a simple
    // message on the document in the control.
    string text = "In docToPrint_PrintPage method.";
    System.Drawing.Font printFont = 
        new Font("Arial", 35, FontStyle.Regular);

    e.Graphics.DrawString(text, printFont,
        Brushes.Black, 10, 10);
}
