PrintTicket.PageOrientation 属性

定义

命名空间:

System.Printing

程序集:

ReachFramework.dll

获取或设置一个值，该值表示打印时如何定向页面内容。

public:
 property Nullable<System::Printing::PageOrientation> PageOrientation { Nullable<System::Printing::PageOrientation> get(); void set(Nullable<System::Printing::PageOrientation> value); };

public System.Printing.PageOrientation? PageOrientation { get; set; }

member this.PageOrientation : Nullable<System.Printing.PageOrientation> with get, set

Public Property PageOrientation As Nullable(Of PageOrientation)

属性值

Nullable<PageOrientation>

用于指定如何定向页面内容的 PageOrientation 值，如 Landscape 或 ReversePortrait。

例外

ArgumentOutOfRangeException

调用代码操作尝试将属性设置为不在 PageOrientation 枚举范围内的值。

示例

以下示例演示如何使用此属性来配置打印作业。

// Use different PrintTickets for different FixedDocuments.
PrintTicket ptFD = new PrintTicket();

if (_firstDocumentPrintTicket <= 1)
{   // Print the first document in black/white and in portrait
    // orientation.  Since the PrintTicket at the
    // FixedDocumentSequence level already specifies portrait
    // orientation, this FixedDocument can just inherit that
    // setting without having to set it again.
    ptFD.PageOrientation = PageOrientation.Portrait;
    ptFD.OutputColor = OutputColor.Monochrome;
    _firstDocumentPrintTicket++;
}

else // if (_firstDocumentPrintTicket > 1)
{   // Print the second document in color and in landscape
    // orientation.  Since the PrintTicket at the
    // FixedDocumentSequence level already specifies portrait
    // orientation, this FixedDocument needs to set its
    // PrintTicket with landscape orientation in order to
    // override the higher level setting.
    ptFD.PageOrientation = PageOrientation.Landscape;
    ptFD.OutputColor = OutputColor.Color;
}

' Use different PrintTickets for different FixedDocuments.
Dim ptFD As New PrintTicket()

If _firstDocumentPrintTicket <= 1 Then
    ' orientation.  Since the PrintTicket at the
    ' FixedDocumentSequence level already specifies portrait
    ' orientation, this FixedDocument can just inherit that
    ' setting without having to set it again.
    ptFD.PageOrientation = PageOrientation.Portrait
    ptFD.OutputColor = OutputColor.Monochrome
    _firstDocumentPrintTicket += 1

Else ' if (_firstDocumentPrintTicket > 1)
    ' orientation.  Since the PrintTicket at the
    ' FixedDocumentSequence level already specifies portrait
    ' orientation, this FixedDocument needs to set its
    ' PrintTicket with landscape orientation in order to
    ' override the higher level setting.
    ptFD.PageOrientation = PageOrientation.Landscape
    ptFD.OutputColor = OutputColor.Color
End If

注解

null此属性的值表示未指定此功能设置。 此外，当值为 null时， (的 XML 版本 PrintTicket 将看不到 SaveTo 和 GetXmlStream) 将不包含此功能的任何标记。

此属性对应于打印架构的PageOrientation关键字 (keyword) 。

可以使用 属性测试打印机支持 PageOrientationCapability 的选项。
