**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 Right As Integer
用法
Dim instance As Control
Dim value As Integer

value = instance.Right

public int Right { get; }

public:
property int Right {
    int get ();
}

/** @property */
public int get_Right ()

public function get Right () : int

属性值

Int32 表示控件右边缘与其容器的工作区左边缘之间的距离（以像素为单位）。

备注

Right 属性的值等于 Left 属性值与 Width 属性值之和。

Right 属性为只读。可以通过更改 Left 或 Width 属性的值或调用 SetBounds、SetBoundsCore、UpdateBounds 或 SetClientSizeCore 方法，来间接地更改此属性值。

示例

下面的代码示例在窗体中创建三个 Button 控件，并使用多种与大小相关的属性和与位置相关的属性来分别设置它们的大小和位置。此示例要求您的 Form 的宽度和高度至少为 300 像素。

' several size and location related properties.
