Use AutoSize para forzar que un formulario cambie de tamaño para ajustarse a su contenido.Use AutoSize to force a form to resize to fit its contents.

Un formulario no cambia de tamaño automáticamente en el diseñador de formularios de Visual Studio, independientemente de los valores AutoSize de AutoSizeMode las propiedades y.A form does not automatically resize in the Visual Studio forms designer, regardless of the values of the AutoSize and AutoSizeMode properties. El formulario cambia de tamaño correctamente en tiempo de ejecución según los valores de estas dos propiedades.The form correctly resizes itself at run time according to the values of these two properties. Por el contrario, un UserControl personalizado cambia automáticamente de tamaño en tiempo de diseño y en tiempo de ejecución.By contrast, a custom UserControl automatically resizes itself both at design time and at run time.

Cuando se AutoSizeusa, MinimumSize se MaximumSize respetan las propiedades y, pero se omite el Size valor actual de la propiedad.When using AutoSize, the MinimumSize and MaximumSize properties are respected, but the current value of the Size property is ignored. El AutoSize uso AutoSizeMode de y también representa AutoScroll la propiedad superflua, ya que no hay forma de reducir el formulario para ocultar los controles contenidos de la vista.Using AutoSize and AutoSizeMode also renders the AutoScroll property superfluous, as there is no way to shrink the form to hide its contained controls from view.

Vea la AutoSizeMode enumeración para obtener información sobre cómo se comporta un formulario AutoSize cuando truees.See the AutoSizeMode enumeration for information on how a form behaves when AutoSize is true.
