允许用户选择一台打印机并选择文档中要打印的部分。
**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）
语法
声明
Public NotInheritable Class PrintDialog
Inherits CommonDialog
用法
Dim instance As PrintDialog
public sealed class PrintDialog : CommonDialog
public ref class PrintDialog sealed : public CommonDialog
public final class PrintDialog extends CommonDialog
public final class PrintDialog extends CommonDialog
备注
创建 PrintDialog 的实例时，读/写属性将被设置为初始值。有关这些值的列表，请参见 PrintDialog 构造函数。
提示
此类不能在 AMD64 处理器上工作，除非将 UseEXDialog 属性设置为 true。
示例
下面的代码示例演示如何使用 PrintDialog 控件来设置 AllowSomePages、ShowHelp 和 Document 属性。若要运行此示例，请将以下代码粘贴到一个窗体中，让该窗体包含一个名为 PrintDialog1 的 PrintDialog 控件和一个名为 Button1 的按钮。此示例假定按钮的 Click 事件和 docToPrint 的 PrintPage 事件已连接到此示例中定义的事件处理方法。
' Declare the PrintDocument object.
Private WithEvents docToPrint As New Printing.PrintDocument
' This method will set properties on the PrintDialog object and
' then display the dialog.
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
' Allow the user to choose the page range he or she would
' like to print.
PrintDialog1.AllowSomePages = True
' Show the help button.
PrintDialog1.ShowHelp = True
' Set the Document property to the PrintDocument for
' which the PrintPage Event has been handled. To display the
' dialog, either this property or the PrinterSettings property
' must be set
PrintDialog1.Document = docToPrint
Dim result As DialogResult = PrintDialog1.ShowDialog()
' If the result is OK then print the document.
If (result = DialogResult.OK) Then
docToPrint.Print()
