注解

Size由于 类是 Visual Basic 中 (Structure的值类型,struct在 Visual C#) 中,它按值返回,这意味着访问 属性将返回控件大小的副本。 因此,调整Width从此属性返回的 的 SizeHeight 属性不会影响 Width 控件的 或Height。 若要调整 Width 控件的 或 Height ,必须设置 控件的 WidthHeight 属性,或使用新的 Size设置 属性Size

注意

为了保持更好的性能,请勿在其构造函数中设置 Size 控件的 。 首选方法是重写 DefaultSize 属性。

注意

在 Windows Server 2003 系统上,的大小 Form 受监视器的最大像素宽度和高度限制。
