Store and Reading connection string in web.config

Handy Tips for freshers:
Connection string in .NET 3.5 (and above) config file:
Do not use appsettings in web.config. Instead use the connectionStrings section in web.config.

<add name="myConnectionString" connectionString="server=\SQLEXPRESS;database=myDb;uid=myUser;password=myPass;" />

To read/access the connection string into your code, use the ConfigurationManager class.
string connStr = ConfigurationManager.ConnectionStrings["myConnectionString"].ConnectionString;

Always store the connection string in a config file.
I saw many freshers save connection string on page(Hard Coding) or in session, Never be among them.

Connection string in .NET 2.0 config file
In the appSettings location, add a key named whatever you like to reference your connection string to.


To read the connection string from code, use the ConfigurationSettings class.
string connStr = ConfigurationSettings.AppSettings("myConnectionString");

Hope this will help few!
