Answer 1

This shows the number of connections per each DB:

SELECT 
    DB_NAME(dbid) as DBName, 
    COUNT(dbid) as NoOfConnections,
    loginame as LoginName
FROM
    sys.sysprocesses
WHERE 
    dbid > 0
GROUP BY 
    dbid, loginame

And this gives total connections:

SELECT 
    COUNT(dbid) as TotalConnections
FROM
    sys.sysprocesses
WHERE 
    dbid > 0

From c#, you can follow :

Call the static method ReleaseObjectPool on the the OleDbConnection - see http://msdn.microsoft.com/en-us/library/system.data.oledb.oledbconnection.releaseobjectpool.aspx
