回答1:

Below is a VB.Net code snippet to retrieve a connection string from the app.config. The project will need a reference to System.Configuration in order to use the ConfigurationManager.

Dim connectionString As String=System.Configuration.ConfigurationManager.ConnectionStrings("myDatabase").ConnectionString

An example App.Config:

<configuration>
    <connectionStrings>
        <add name="myDatabase" connectionString="Data Source=MyServer;Initial Catalog=MyDatabase;Integrated Security=SSPI" />
    </connectionStrings>
</configuration>
