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。
public:
property System::Drawing::Point Location { System::Drawing::Point get(); void set(System::Drawing::Point value); };C#
public System.Drawing.Point Location { get; set; }member this.Location : System.Drawing.Point with get, setPublic Property Location As PointPoint，表示控件的左上角相对于其容器的左上角。
下面的代码示例创建 GroupBox 并设置其一些常见属性。 该示例创建 并在 TextBox 分组框中设置其 Location 。 接下来，它设置 Text 组框的 属性，并将组框停靠到窗体的顶部。 最后，它通过将 属性设置为 Enabledfalse来禁用分组框，这会导致禁用组框中包含的所有控件。

Point由于 类是 Visual Basic 中 (Structure的值类型，struct在 Visual C#) 中，它由值返回，这意味着访问 属性将返回控件左上角点的副本。 因此，调整X从此属性返回的 的 Point 或 Y 属性不会影响控件的 Left、Right、 Top或 Bottom 属性值。 若要调整这些属性，请单独设置每个属性值，或使用新的 Point设置 属性Location。
Control如果 为 ，Form则 Location 属性值表示屏幕坐标中的 左上角Form。
