| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GetValue | Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ReadLocalValue | Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.) |

A Style contains a collection of one or more Setter objects. Each Setter has a Property and a Value. The Property is the property of the element the style is applied to. The Value is the value that is applied to the property.
You must specify both the Property and Value properties on a Setter or an exception is thrown.
The following example creates two styles: one for a TextBlock and one for a TextBox. The style for the TextBlock sets the Foreground, FontSize, and VerticalAlignment properties. The style for the TextBox sets the Width, Height, Margin, Background, and FontSize properties. Each style is applied to two instances of a control to create a uniform appearance for each TextBlock and TextBox.
