When the FlatStyle property is set to FlatStyle.System, any values assigned to the ImageList, Image, ImageIndex, and ImageAlign properties are ignored. In addition, the TextAlign property ignores any property values that are not vertical property settings. Horizontally aligned settings of the TextAlign property are aligned to the top of the control. For example, if you set the TextAlign property to ContentAlignment.TopCenter, ContentAlignment.MiddleCenter, or ContentAlignment.BottomCenter, when the FlatStyle property is set to FlatStyle.System, the text in the Label control will be aligned to the top and center locations within the bounds of the control.
In the .NET Framework version 1.1, setting the FlatStyle property to FlatStyle.System does not cause the value of the TextAlign property to be ignored. In addition, the property has no effect in the derived class, LinkLabel.
