In the setting of the web program in the ASP.NET we must use Web.config to store database connection words. In fact this is
Very good practice, because you can save us a lot of troubles can also help us avoid unnecessary misplacement, there are many cases
I am doing this. It records this information through XML. The specific is in
Tagged in the mark. Please see an example of an Oracle as follows:
And you can write like this in your app, as follows:
String conn = configurationSettings.appsettings ["OracleConnectionString"]; OLEDBCONNECTION MyConnection = New OLEDBCONNECTION (CONN);
Very easy? Don't you need to enter the same connection word every time, don't remember those nasty information, just need a good book.
Name can be.
Ok, I am here to give some other connection words.

SQL Server is in system.data.sqlclient
Sqlconnection osqlconn = new sqlconnection (); osqlconn.connectionstring = "data source = (local);" "Initial catalog = mysqlserdbname;" "integrated security = sspi"; osqlconn.open ();
