Question

Everytime my application runs a stored procedure it does something like this:

using (DbBase conn = new DbBase())
{      
    //call sproc
}

the DBBase() opens the connection with a LINQ DataContext.

What I wanted to know, if there’s a way to know if a connection has already been opened, and use that instead of opening a new one. That verification should be done inside the DbBase() constructor that goes like this:

ClientDB = new ClientDBDataContext([ConnectionString from web.config]);

Thank you

Answer 1

You look at the State property of any DBConnection object, and it will tell you if it’s open, closed, connecting, executing, fetching or broken.

By utilizing the using{ } statement though, you’re guaranteed that the connection is being closed when the object goes out of scope.
