Hi Michael,

If I'm not mistaken, you should simply use .
There are more properties on the Host class, to access other settings.

Hope this helps.

Assuming that this is a WebForms module, you will want to introduce a field to store the IHostSettingsService, and typically you would initialize it in the constructor, using the DependecyProvider property that you inherit from PortalModuleBase. See https://www.andrewhoefling.com/Blog/Post/dnn-dependency-injection-webforms-modules for more details.
FYI, there's a pending pull request which would make WebForms modules work the same way as Web API controllers and MVC controllers, i.e. just introducing a constructor with IHostSettingsService as a parameter.

Thank you both,

Brian, if I understand that right, it is done like with the INavigationManager.

public MyControl()
{
  _hostSettings = DependencyProvider.GetRequiredService< IHostSettingsService >();
}

private readonly IHostSettingsService _hostSettings;

protected void SomeMethod()
{
…
  string allowedExtensions;
  if (!(_hostSettings.GetSettingsDictionary().TryGetValue("FileExtensions", out allowedExtensions)))
  {
   …

That did work (without the spaces inside the angle brackets), thank you...

Happy DNNing!
Michael

Hi,

When I try something like this:

Snippet <!--StartFragment-->

IHostSettingsService hostSettingsService = DotNetNuke.Common.Globals.DependencyProvider.GetRequiredService < IHostSettingsService > ();

<!--EndFragment-->

It doesn't work. Error: "'Globals' does not contain a definition for 'DependencyProvider'"

This error makes sense (cannot access it from my code) because DependencyProvider is internal in Dotnetnuke.dll. 

internal static IServiceProvider DependencyProvider
        {
            get
            {
                return Globals.dependencyProvider;
            }
            set
            {
                Globals.dependencyProvider = value;
                INotifyPropertyChanged notifyPropertyChanged = Globals.dependencyProvider as INotifyPropertyChanged;
                INotifyPropertyChanged notifyPropertyChanged1 = notifyPropertyChanged;
                if (notifyPropertyChanged == null)
                {
                    Globals.OnDependencyProviderChanged(null, null);
                    return;
                }
                notifyPropertyChanged1.PropertyChanged += new PropertyChangedEventHandler(Globals.OnDependencyProviderChanged);
            }
        }

 

Therefore, I don't understand how can I get and save host settings without using deprecated code. 

Any ideas?

 

EDIT:

It does work for example in this DNN's code:  \Dnn.Platform\Dnn.AdminExperience\Dnn.PersonaBar.Extensions\Components\TaskScheduler\TaskSchedulerController.cs, because \Dnn.Platform\DNN Platform\Library\Properties\AssemblyInfo.cs says "[assembly: InternalsVisibleTo("Dnn.PersonaBar.Library")] "

I coudn't find any way to get & save host settings from non-dnn core code. 

 

Thanks

 

 

 

 

 

 

 

It depends on where in your code you're referencing it. From a Web API controller, an MVC controller, or a scheduled task, you just need to add IHostSettingsService as a constructor argument (you may need to add the constructor altogether). From a control inheriting from PortalModuleBase, you'll need to use the DependencyProvider property. Otherwise, at the moment, those services are not available outside of internal code, and you'll need to stay with the obsolete code for now. The current plan is to adjust a bunch of underlying code in DNN 10 to use the dependency injection container, but there will be slight differences around object lifetime that we can't make until a major version change. Hopefully at that time everything that DNN creates will be available to use constructor injection to access the services in the DI container.

I was easier than I thought, and without using IHostSettingsService.

At least for now, I don't get any obsolete warning when using code like this:

Snippet <!--StartFragment-->

var ctl = new HostController();
var myValue = ctl.GetString("myKey");
          
ctl.Update(key: "mykey",
            value: myValue,
            clearCache: true);

<!--EndFragment-->

Thanks,

H
