CheckBox.CheckAlign 属性

获取或设置 CheckBox 控件上的复选框的水平和垂直对齐方式。

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

语法

声明
<BindableAttribute(True)> _
<LocalizableAttribute(True)> _
Public Property CheckAlign As ContentAlignment
用法
Dim instance As CheckBox
Dim value As ContentAlignment

value = instance.CheckAlign

instance.CheckAlign = value

[BindableAttribute(true)] 
[LocalizableAttribute(true)] 
public ContentAlignment CheckAlign { get; set; }

[BindableAttribute(true)] 
[LocalizableAttribute(true)] 
public:
property ContentAlignment CheckAlign {
    ContentAlignment get ();
    void set (ContentAlignment value);
}

/** @property */
public ContentAlignment get_CheckAlign ()

/** @property */
public void set_CheckAlign (ContentAlignment value)

public function get CheckAlign () : ContentAlignment

public function set CheckAlign (value : ContentAlignment)

属性值

ContentAlignment 值之一。默认值为 MiddleLeft。

异常

异常类型	条件
InvalidEnumArgumentException	所分配的值不是 ContentAlignment 枚举值之一。

示例

下面的代码示例将在一个标签中显示三个属性的值。连续单击该控件会使 ThreeState 属性交替设置为 true 和 false，而 CheckAlign 会交替设置为 ContentAlignment 的 MiddleRight 和 MiddleLeft 值。此示例显示属性值如何在更改 ThreeState 属性和选中该控件时发生更改。此示例要求 CheckBox、Label 和 Button 已全部在窗体上实例化，并且标签的大小足以显示三行文本和对 System.Drawing 命名空间的引用。应当在该控件的 Click 事件处理程序中调用此代码。
