Close SqlConnection in the Finally when using “Using”

Question

I want to close the SqlConnection in the Finally since the using not really close it and the connection pool gets full. but I don\'t realize what\'s the right way to fo that

Answer 1

using (var conn = new SqlConnection(_dbconnstr)) 
{
    //code
}

is expaded to:

SqlConnection conn = new SqlConnection(_dbconnstr);
try
{
    //code
}
finally
{
    conn.Dispose();
}

So you should handle errors but you can forget about closing connection.
