How to get the dimension of an angle mate?

Hi,

There is a situation where I have a limit angle mate in my assembly. Since it is a limit angle, the components can move between min. and max. values. So, I need to get the current value of angle for further changes. I am extremely new to SolidWorks API and I don't know much about it. I'm learning from the API help and developing add-ins in C#. I tried everything I could but of no use. I hope someone can help me out. Thanks.
