It helped me a lot today. I knew it's useful but now I'm sure it's twice useful!!
ASP.NET 2.0 comes with a cool new feature that lets you to deal with configuration files on fly via APIs. You can read a configuration file then modify it through your codes.
Alright, this isn't something new for a real .NET 2.0 developer but I have to point it again! You can read configuration files from remote server. System.Web.Configuration.ConfigurationManager.OpenWebConfiguration() method has six overloads that let you to read configuration files locally or remotely then assign them to a Configuration object to modify them.
What will follow is an instance that reads a Community Server configuration file from a server, writes its connectionstring and adds a new AppSettings item then saves the changes.
protected void Page_Load(object sender, EventArgs e)
{
Configuration configuration = WebConfigurationManager.
OpenWebConfiguration("/CS2160804900", "Default Web Site",
null, "KEYVANNAYYERI");
// See what's there
Response.Write(configuration.AppSettings.Settings
["SiteSqlServer"].Value);
// Add something new
configuration.AppSettings.Settings.Add("Keyvan", "Nayyeri");
// Save changes
configuration.Save();
}
If I open this configuration file, can see the changes:
<appSettings>
<add key="SiteSqlServer"
value="server=(local);uid=;pwd=;Trusted_Connection=yes;database=CS2160804900" />
<add key="SiteSqlServerOwner"
value="dbo" />
<add key="MachineValidationKey"
value="B387B75D996FF473FC21EC10605CA49E520E9B11" />
<add key="MachineDecryptionKey"
value="B3C730067B56DD5381F5BF473E83E3038181459C0F33CEE6" />
<add key="MachineValidationMode"
value="SHA1" />
<add key="ComponentArt.Web.UI.ClientScriptLocation"
value="~/Utility/componentart_webui_client" />
<add key="Telligent.Web.UI.ClientScriptPath"
value="~/Utility/telligent_web_ui" />
<add key="Keyvan"
value="Nayyeri" />
</appSettings>
