how to use C# entity framework

1.To setup dynamic connection string for Entity Framework (shortly EF), supposing that your ObjectContext class is named MyDataContext, you have to use its constructor that accept a connection string as parameter like in the example below;

2.To query EF by using this dynamic connection string you have to use the code like in the next example:

Student student = null;
using (MyDataContext dataContext = new MyDataContext(yourConnectionString))
                    {
                        var query = from st in dataContext .Students
                            where st.StudentName == "Bill"
                            select st;
                        // 
                        student = query.FirstOrDefault();  
                    }
