获取或设置该页的纸张大小。

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

语法

声明
Public Property PaperSize As PaperSize
用法
Dim instance As PageSettings
Dim value As PaperSize

value = instance.PaperSize

instance.PaperSize = value

public PaperSize PaperSize { get; set; }

public:
property PaperSize^ PaperSize {
    PaperSize^ get ();
    void set (PaperSize^ value);
}

/** @property */
public PaperSize get_PaperSize ()

/** @property */
public void set_PaperSize (PaperSize value)

public function get PaperSize () : PaperSize

public function set PaperSize (value : PaperSize)

属性值

PaperSize，它表示纸张大小。默认值为打印机的默认纸张大小。

异常

异常类型	条件
InvalidPrinterException	PrinterSettings.PrinterName 属性中指定的打印机不存在或者没有已安装的默认打印机。

备注

PaperSize，通过 PaperSize.Kind 属性来表示纸张的大小，该属性包含一个 PaperKind 值。

将页面的 PaperSize 属性设置为有效的 PaperSize（可通过 PrinterSettings.PaperSizes 集合获得）。

有关如何指定自定义纸张大小的信息，请参见 PaperSize 构造函数。

示例

下面的代码示例设置文档的默认页的三个属性（包括根据 comboPaperSize 组合框中选定的大小确定的纸张大小），然后使用 Print 方法打印该文档。该示例要求名为 printDoc 的 PrintDocument 变量和特定的组合框都已存在。
