Fetching dependent field values

Fetching dependent field values

Hi

I have created a custom field (picklist) named Priority. I have made this Priority field as dependent to Lead Status.
Now I want to fetch values of Lead Status and Priority together.
Suppose I have mapped 'Not Contacted' (lead status) to 1,2 (Priority), now I want to fetch something like Not Contacted with 1,2.

I want to achieve this in C#. I am using REST api.
Please help me out.
