asp.net - How to retrieve the databaseName and the serverName from the connectionstring in the webconfig?

Question

How Do I get the connection string from the Web Config? I want to Display the database and the server name on to my master ASP.net page(C#).

The connection string in my web.config looks:

<add name="Application_ConnectionString" connectionString="Data Source=ServerName;Initial Catalog=DatabaseName;Persist Security Info=True;Connection Timeout =60;Integrated Security=SSPI" providerName="System.Data.SqlClient"/>

Answer 1

There's also the SqlConnectionStringBuilder class:

var connectionString = 
  new System.Data.SqlClient.SqlConnectionStringBuilder("Data Source=ServerName;Initial Catalog=DatabaseName;Persist Security Info=True;Connection Timeout =60;Integrated Security=SSPI"); 

Console.WriteLine(connectionString.DataSource);
Console.WriteLine(connectionString.InitialCatalog);
// ...

Response to comment:

To get the connection strings directly from configuration, use:

foreach (ConnectionStringSettings c in System.Web.Configuration.WebConfigurationManager.ConnectionStrings)
{
    var connectionString = new SqlConnectionStringBuilder(c.ConnectionString)
    //connectionString.DataSource; // server name
    //connectionString.InitialCatalog; // database name
}

Note that this will include connection strings in your machine.config (e.g. data source=.SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true). If you don't want to see that you can filter it in code or add a <clear /> element to your web.config before your connection strings.
