In this example, you will learn how to write a connection string in Web.Config, Writing a connection string in Web.Config makes you easy to change the database name, server name, username and password of database login. Doing this, you don't need to change a connection string setting in all pages if your Web project has a large number of pages.

Here's an example


              <!--Attach a database file which is placed inside the data directory of Web Application-->

              <add name="ConnectionString_1"

                      connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnetdb.mdf;

                                        User Instance=true" providerName="System.Data.SqlClient"/>


              <!--Attach a database file which is placed inside the data directory of Web Application-->

              <add name="ConnectionString_2"

                      connectionString="Data Source=[SERVER_NAME];AttachDbFilename=[DATABASE_NAME AND PATH e.g c:\app_data\aspxtutorial.mdf];

                                        Integrated Security=True;Connect Timeout=30;User Instance=True" providerName="System.Data.SqlClient"/>


              <!--Relative path of database in side connection string-->

              <add name="ConnectionString_3"

                      connectionString="server=[SERVER_NAME];database=[DATABASE_NAME];uid=[USER ID];password=[PASSWORD];

                                        Connect Timeout=20; Max Pool Size=2000  " />
