PageSettings.Color 屬性
定義
重要
部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
取得或設定值，指出頁面是否應該以彩色列印。
public:
property bool Color { bool get(); void set(bool value); };public bool Color { get; set; }member this.Color : bool with get, setPublic Property Color As Boolean屬性值
如果頁面以彩色列印為 true，否則為 false。 由印表機決定預設值。
例外狀況
以 PrinterName 屬性命名的印表機並不存在。
範例
如果印表機支援，下列程式碼範例會列印具有第一頁色彩的檔。 此範例會要求 PrintDocument 已建立名為 printDoc 的變數，並 PrintPage 處理 和 QueryPageSettings 事件。
使用此範例的 System.Drawing 和 System.Drawing.Printing 命名空間。
private:
void MyButtonPrint_OnClick( Object^ sender, System::EventArgs^ e )
{
// 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 )
{
// If the printer supports printing in color, then override the printer's default behavior.
if ( printDoc->PrinterSettings->SupportsColor )
{
// Set the page default's to not print in color.
printDoc->DefaultPageSettings->Color = false;
}
// Provide a friendly name, set the page number, and print the document.
printDoc->DocumentName = "My Presentation";
currentPageNumber = 1;
printDoc->Print();
}

MessageBox::Show( "Printer is not valid" );
}
}
void MyPrintQueryPageSettingsEvent( Object^ sender, QueryPageSettingsEventArgs^ e )

// Determines if the printer supports printing in color.
if ( printDoc->PrinterSettings->SupportsColor )

if (currentPageNumber == 1 ) {
e.PageSettings.Color = true;
}
}
}
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 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"

printDoc.Print()
Else
MessageBox.Show("Printer is not valid")
End If
End Sub
Private Sub MyPrintQueryPageSettingsEvent(ByVal sender As Object, ByVal e As QueryPageSettingsEventArgs)
' Determines if the printer supports printing in color.
If printDoc.PrinterSettings.SupportsColor Then
' If the printer supports color printing, use color.
If currentPageNumber = 1 Then
e.PageSettings.Color = True
End If
End If
End Sub
備註
您可以使用 PrinterSettings.SupportsColor 屬性來判斷印表機是否支援色彩列印。 如果印表機支援色彩，但您不想以色彩列印，請將 Color 屬性設定為 false 。 預設值為 true 。
