How to get the mapscale using ArcGIS API for WPF

[SolidSmoke]

Please advise me how to get the mapscale of the Map using ArcGIS API for WPF. Or how to get the same from the ScaleBar control of ArcGIS API for WPF. This is very urgent.

Map.Resolution is giving the map resolution on map units per pixels.

From this resolution you can calculate the scale.
For example, if your map units are feet and your device is 96 dpi,  the map scale is map.Resolution(feet/pixel) * 12(in/foot) * 96(pixel/in).

See the scale discussion in the class reference for the Map class:
