PageSetupDialog.ShowNetwork 属性

获取或设置一个值，该值指示“网络”按钮是否可见。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
Public Property ShowNetwork As Boolean
用法
Dim instance As PageSetupDialog
Dim value As Boolean

value = instance.ShowNetwork

instance.ShowNetwork = value

public bool ShowNetwork { get; set; }

public:
property bool ShowNetwork {
    bool get ();
    void set (bool value);
}

/** @property */
public boolean get_ShowNetwork ()

/** @property */
public void set_ShowNetwork (boolean value)

public function get ShowNetwork () : boolean

public function set ShowNetwork (value : boolean)

属性值

如果“网络”按钮是可见的，则为 true；否则为 false。默认为 true。

示例

下面的代码示例使用 PageSettings、PrinterSettings 和 ShowNetwork 属性阐释了 PageSetupDialog。若要运行此示例，请将它放到一个包含一个 Button（名为 Button1）、一个 ListBox（名为 ListBox1）和一个 PageSetupDialog（名为 PageSetupDialog1）的窗体中。确保该按钮的 Click 事件与此示例中的事件处理方法相连接。

' user clicks OK in the dialog, selected results of
