PageSettings.Color 属性

获取或设置一个值,该值指示是否应以彩色打印该页。

**命名空间:**System.Drawing.Printing
**程序集:**System.Drawing(在 system.drawing.dll 中)

语法

声明
Public Property Color As Boolean
用法
Dim instance As PageSettings
Dim value As Boolean

value = instance.Color

instance.Color = value
public bool Color { get; set; }
public:
property bool Color {
    bool get ();
    void set (bool value);
}
/** @property */
public boolean get_Color ()

/** @property */
public void set_Color (boolean value)
public function get Color () : boolean

public function set Color (value : boolean)

属性值

如果该页应以彩色打印,则为 true;反之,则为 false。默认值由打印机决定。

异常

异常类型 条件

InvalidPrinterException

PrinterSettings.PrinterName 属性中命名的打印机不存在。

备注

可以使用 PrinterSettings.SupportsColor 属性确定打印机是否支持彩色打印。如果打印机支持彩色打印,但是您又不想彩色打印,请将 Color 属性设置为 false。默认值为 true

示例

下面的代码示例打印文档并彩印文档的第一页(如果打印机支持该功能)。该示例要求已创建名为 printDocPrintDocument 变量,并且处理 PrintPageQueryPageSettings 事件。

在此示例中使用 System.DrawingSystem.Drawing.Printing 命名空间。

Private Sub MyButtonPrint_OnClick(ByVal sender As Object, ByVal e As System.EventArgs)

    ' Set the printer name and ensure it is valid. If not, provide a message to the user.
    printDoc.PrinterSettings.PrinterName = "\\mynetworkprinter"

    If printDoc.PrinterSettings.IsValid Then

        ' If the printer supports printing in color, then override the printer's default behavior.
        if printDoc.PrinterSettings.SupportsColor then

            ' Set the page default's to not print in color.
            printDoc.DefaultPageSettings.Color = False
        End If

        ' Provide a friendly name, set the page number, and print the document.
        printDoc.DocumentName = "My Presentation"
