How to get IEditorOperations from IVsTextView?

Question

I'm developing my first Visual Studio (2015 Community) Command Menu and I'm trying to get access to IEditorOperations to delete text, send backspace etc. but I'm not sure how to. I can do:

var Service = Provider.GetService(typeof(IEditorOperationsFactoryService)) as IEditorOperationsFactoryService;
Service.GetEditorOperations(???);

I'm not sure what to pass in the ??? since I don't have access to an ITextView instead what I have is a IVsTExtView via:

IVsTextView View;
IVsTextManager Manager = (IVsTextManager)ServiceProvider.GetService(typeof(SVsTextManager));
int MustHaveFocus = 1;
Manager.GetActiveView(MustHaveFocus, null, out View);

When creating the Command Menu, VS generates a template for me with a private ctor creating the command service, binding it to the command set id etc. An overridden Initialize method, and a bunch of properties.

Any ideas?

EDIT: After help from Sergey, I managed to get a bit further. But now I get a null when I try to get the IEditorOperationsFactoryService, all the other values are valid.

static IEditorOperations GetEditorService(IServiceProvider Provider, IVsTextView VsView)
    {
        IEditorOperations Result;

        try
        {
            var Model = (IComponentModel)Provider.GetService(typeof(SComponentModel));
            var Editor = (IEditorOperationsFactoryService)Provider.GetService(typeof(IEditorOperationsFactoryService)); // returns null

            var Adaptor = Model.GetService<IVsEditorAdaptersFactoryService>();
            IWpfTextView TextView = Adaptor.GetWpfTextView(VsView);
            Result = Editor.GetEditorOperations(TextView);
        }
        catch (Exception e)
        {
            System.Windows.Forms.MessageBox.Show(e.ToString());
            Result = null;
        }

        return (Result);
    }

Answer 1

You can get IEditorOperationsFactoryService instance from variable named Model, like this:

var Model = (IComponentModel)this.ServiceProvider.GetService(typeof(SComponentModel));

var Editor = (IEditorOperationsFactoryService)Model.GetService<IEditorOperationsFactoryService>();

Nb

The generic version works for some reason but the non-generic one returns null. Thanks! – Reagent

Answer 2

You can get IWpfTextView (that implements ITextView) from IVsTextView using:

IVsTextView textView = ...;
IWpfTextView v = GetEditorAdaptersFactoryService().GetWpfTextView(textView);

private Microsoft.VisualStudio.Editor.IVsEditorAdaptersFactoryService GetEditorAdaptersFactoryService()
{
    Microsoft.VisualStudio.ComponentModelHost.IComponentModel componentModel =
        (Microsoft.VisualStudio.ComponentModelHost.IComponentModel)serviceProvider.GetService(
            typeof(Microsoft.VisualStudio.ComponentModelHost.SComponentModel));
    return componentModel.GetService<Microsoft.VisualStudio.Editor.IVsEditorAdaptersFactoryService>();
}

Unready

Editor doesn't exist inside VisualStudio namepsace, nor ComponentModelHost. Do I need to reference a certain assembly? – Reagent

IVsEditorAdaptersFactoryService is defined in Microsoft.VisualStudio.Editor.dll. IComponentModel is defined in Microsoft.VisualStudio.ComponentModelHost.dll. – Unready

Now I get a null when getting IEditorOperationsFactoryService back from GetService. Please see edits. – Reagent
