ImageList.Images 属性

项目
08/17/2007

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

语法

声明
Public ReadOnly Property Images As ImageCollection
用法
Dim instance As ImageList
Dim value As ImageCollection

value = instance.Images

public ImageCollection Images { get; }

public:
property ImageCollection^ Images {
    ImageCollection^ get ();
}

/** @property */
public ImageCollection get_Images ()

public function get Images () : ImageCollection

属性值

图像集合。

备注

如果尚未创建图像集合，则会在检索此属性时创建该图像集合。

示例

下面的代码示例演示如何构造 ImageList、如何向 Images 属性添加图像、如何设置 ImageSize 属性以及如何使用 Draw 方法。若要运行此示例，请将它放到一个包含名为 Button1 的按钮的窗体中。该示例假定 c:\Windows\ 中存在 FeatherTexture.bmp 和 Gone Fishing.bmp。如果您的系统中不存在这些位图，或者它们存在于其他位置，请对示例进行相应的更改。
