Control.Location 属性
获取或设置该控件的左上角相对于其容器的左上角的坐标。
**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）
语法
声明
<LocalizableAttribute(True)> _
Public Property Location As Point
用法
Dim instance As Control
Dim value As Point
value = instance.Location
instance.Location = value
[LocalizableAttribute(true)]
public Point Location { get; set; }
[LocalizableAttribute(true)]
public:
property Point Location {
Point get ();
void set (Point value);
}
/** @property */
public Point get_Location ()
/** @property */
public void set_Location (Point value)
public function get Location () : Point
public function set Location (value : Point)
属性值
Point，它表示控件的左上角相对于其容器的左上角。
备注
由于 Point 类是值类型（在 Visual Basic 中是 Structure，在 Visual C# 中是 struct），它按传值方式返回，意味着访问该属性将返回控件的左上点的副本。因此，调整从该属性返回的 Point 的 X 或 Y 属性将不影响控件的 Left、Right、Top 或 Bottom 属性值。若要调整这些属性，请分别设置每个属性值，或用新的 Point 设置 Location 属性。
如果 Control 是 Form，那么 Location 属性值表示 Form 的左上角（以屏幕坐标表示）。
示例
下面的代码示例创建 GroupBox 并设置该控件的一些通用属性。该示例创建一个 TextBox 并设置它在分组框中的 Location。接着，它设置分组框的 Text 属性，并将此分组框停靠在窗体的顶部。最后，它通过将 Enabled 属性设置为 false 来禁用分组框，这将导致分组框中的所有控件都被禁用。

Dim textBox1 As New TextBox()
