Application.EnableVisualStyles 方法

启用应用程序的可视样式。

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

语法

声明
Public Shared Sub EnableVisualStyles
用法

Application.EnableVisualStyles

public static void EnableVisualStyles ()

public:
static void EnableVisualStyles ()

public static void EnableVisualStyles ()

public static function EnableVisualStyles ()

备注

此方法为应用程序启用可视样式。如果控件和操作系统支持视觉样式，则控件将以视觉样式进行绘制。若要使 EnableVisualStyles 生效，必须在应用程序中创建任何控件之前调用它；EnableVisualStyles 通常是 Main 函数的第一行。当调用 EnableVisualStyles 时，无需单独的清单即可启用可视化样式。

提示

在 .NET Framework 2.0 之前的版本中，必须将某些控件（如从 ButtonBase 派生的控件）的 FlatStyle 属性设置为 FlatStyle.System，以便使用可视样式绘制控件。如果应用程序是使用 .NET Framework 2.0 编写的，则无需此操作。

提示

此方法不会影响 Internet Explorer 中承载的控件。

Windows XP Home Edition、Windows XP Professional x64 Edition、Windows Server 2003 平台说明： 只有这些平台支持可视样式。

示例

下面的代码示例演示如何在 Main 函数中调用 EnableVisualStyles 来启用应用程序的视觉样式。
