Sharp Development

[sragan]

I was trying to get some of the examples from the Revit API Help to work with the Sharp Development version included with Revit 2015.

I got the "hello world" message box to work, but I got stuck after that.

If I go to the Macros in Revit, and create a new module, and create a new Macro under that, I can't figure out how to add the code from the "Retrieve Selected Elements" example.

Can anyone offer some insight into what I need to do to make these examples work? The examples all seem to make a IExternalCommand or IExternalApplication interface. That doesn't seem to work with Sharp. And I'm not sure what to do with the extra code Sharp creates.

For example, I was trying to get this to work:

[Autodesk.Revit.Attributes.Transaction(TransactionMode.ReadOnly)]
public class Document_Selection : IExternalCommand
{
    public Autodesk.Revit.UI.Result Execute(ExternalCommandData commandData,
        ref string message, ElementSet elements)
    {
        try
        {
            // Select some elements in Revit before invoking this command

            // Get the handle of current document.
            UIDocument uidoc = commandData.Application.ActiveUIDocument;
                
            // Get the element selection of current document.
            Selection selection = uidoc.Selection;
            ICollection<ElementId> selectedIds = uidoc.Selection.GetElementIds();

            if (0 == selectedIds.Count)
            {
                // If no elements selected.
                TaskDialog.Show("Revit","You haven't selected any elements.");
            }
            else
            {
                String info = "Ids of selected elements in the document are: ";
                foreach (ElementId id in selectedIds)
                {
                    info += "\n\t" + id.IntegerValue;
                }

                TaskDialog.Show("Revit",info);
            }
        }
        catch (Exception e)
        {
            message = e.Message;
            return Autodesk.Revit.UI.Result.Failed;
        }

        return Autodesk.Revit.UI.Result.Succeeded;
    }
    /// </ExampleMethod>
}

But sharp already has a class definition that looks like this:

public partial class ThisApplication

and another that looks like this:

public void Document_Selection()

My application fails when I try to build it with the error "The name commanddata does not exist in the current context (CS103)"

add to the using block: using Autodesk.Revit.UI;
or prefix it: Autodesk.Revit.UI.ExternalCommandData
