Service bus Queue Shared access policy

I created a shared access policy with only send permission for a service bus queue. I used to send messages from web role to  service bus using service bus connection string. Now the requirement is , instead of using service bus connection string I need to create a shared policy for service bus Queue with only send permission and use that policy for sending messages to service bus from web role.

I need to do this in c#, but I do not know how to create connection string for servicebus queue with shared access policy. Kindly explain how to get Service bus Queue Shared access policy connection string in c#.
