Equals | Determines whether the current FontWeight object is equal to a specified object. (Overrides ValueType.Equals(Object).) |

Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
|
GetHashCode | Retrieves the hash code for this object. (Overrides ValueType.GetHashCode().) |
|
GetType | Gets the Type of the current instance. (Inherited from Object.) |
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |

Remarks
Weight differences are generally differentiated by an increased stroke or thickness that is associated with a given character in a typeface, as compared to a "normal" character from that same typeface.
Note Not all weights are available for all typefaces. When a weight is not available for a typeface, the closest matching weight is returned.
This structure provides compatibility between Silverlight and WPF properties that specify a font weight. The compatibility requirement is that in JavaScript API for Silverlight, the relevant properties referenced FontWeight, which is an enumeration, whereas WPF relevant properties referenced FontWeights, a class with static properties.
FontWeight is the value type for Silverlight properties or attributes that specify a font weight value, but you must use static properties of FontWeights to provide a FontWeight value. In XAML, you specify the name of a FontWeights property as the attribute value. This functionality is enabled by native XAML parsing behavior that processes the string value.

The FontWeights values correspond to the usWeightClass definition in the OpenType specification. The usWeightClass represents an integer value between 1 and 999. Lower values indicate lighter weights; higher values indicate heavier weights.
Do not use the value UltraBold; this value is not supported by Silverlight 5.
