You can use the following code in the Page.Load event handler to test a connection and write its status to a label (as shown in Figure 7-2): // Create the Connection object. string connectionString = WebConfigurationManager.ConnectionStrings["Northwind"].ConnectionString; SqlConnection con = new SqlConnection(connectionString); try { // Try to open the connection. con.Open(); lblInfo.Text = "Server Version: " + con.ServerVersion; lblInfo.Text += " Connection Is: " + con.State.ToString(); } catch (Exception err) { // Handle an error by displaying the information. lblInfo.Text = "Error reading the database. "; lblInfo.Text += err.Message; } finally { // Either way, make sure the connection is properly closed. // Even if the connection wasn't opened successfully, // calling Close() won't cause an error. con.Close(); lblInfo.Text += " Now Connection Is: "; lblInfo.Text += con.State.ToString(); } Figure 7-2 shows the results of running this code.

Figure 7-2. Testing a connection Connections are a limited server resource. This means it s imperative that you open the connection as late as possible and release it as quickly as possible. In the previous code sample, an exception handler is used to make sure that even if an unhandled error occurs, the connection will be closed in the finally block. If you don t use this design and an unhandled exception occurs, the connection will remain open until the garbage collector disposes of the SqlConnection object. An alternate approach is to wrap your data access code in a using block. The using statement declares that you are using a disposable object for a short period of time. As soon as the using block ends, the CLR releases the corresponding object immediately by calling its Dispose() method. Interestingly, calling the Dispose() method of a Connection object is equivalent to calling Close(). That means you can rewrite the earlier example in the following, more compact, form: string connectionString = WebConfigurationManager.ConnectionStrings["Northwind"].ConnectionString; SqlConnection con = new SqlConnection(connectionString); using (con) { con.Open(); lblInfo.Text = "Server Version: " + con.ServerVersion; lblInfo.Text += " Connection Is: " + con.State.ToString(); } lblInfo.Text += " Now Connection Is: "; lblInfo.Text += con.State.ToString(); The best part is that you don t need to write a finally block the using statement releases the object you re using even if you exit the block as the result of an unhandled exception.
