Problem in Connection String with using database. RRS feed

  • Question

  • Hi,


    I have the problem with the connection string that i am writing in the code.

    I use the following code:


    Sqlconnection con=new Sqlconnection("CONNECTION STRING");


    Now here when i change my databse's location I have to change the connection string.


    What can I do for that?


    I want that even if I change the location of my database, I don't change the connection string.


    Reply as early as possible.

  • The connection string is the only way your program can find your database.

  • hi manish

    its better to right the connection string code in app config file and if u change the datasource just you have to change that name in app config file rest everything will be same you dont have to crate any new connection string for every time you change your database


    this code you have to write in app.config file


    <add name="myconString" connectionString="Data Source =database(instance of your local sql)  ; Initial Catalog = database name ; Integrated Security = True;"/>



    and in conole you have to write like this


    SqlConnection myCon = new SqlConnection();

    string conString = ConfigurationManager.ConnectionStrings["myconString"].ConnectionString;

    myCon.ConnectionString = conString;


    and then conitnue doing you operations


    the only chage u have to manke is in app.config file  when you change the database name or database source thats it


    i think it will help solving your querry
