❔ XML Read XML and save as dictionary

Hi all. I want to read XML data and convert to a dictionary, I have given this go with: This is how i write:

......Above
                XmlTextWriter writer = new XmlTextWriter(StoredDataFile, System.Text.Encoding.UTF8);
                writer.WriteStartDocument(true);
                writer.Formatting = Formatting.Indented;
                writer.Indentation = 2;
                writer.WriteStartElement(startingText);
                //write dict to xml
                foreach (KeyValuePair<string, bool> kvp in toWrite)
                {
                    writer.WriteStartElement("Values");
                    writer.WriteAttributeString("key", kvp.Key);
                    writer.WriteAttributeString("value", kvp.Value.ToString());
                    writer.WriteEndElement();
                }
......Below

                XmlTextWriter writer = new XmlTextWriter(StoredDataFile, System.Text.Encoding.UTF8);
                writer.WriteStartDocument(true);
                writer.Formatting = Formatting.Indented;

                    writer.WriteAttributeString("key", kvp.Key);
                    writer.WriteAttributeString("value", kvp.Value.ToString());
                    writer.WriteEndElement();
                }

This is how I am reading:

public static Dictionary<string, bool> ReadFromXML(string tagToRead)
        {
            Dictionary<string, bool> outDict = new Dictionary<string, bool>();
            //look for the tag tagtoread in the XML tree, then return all values in that tag as a dictionary
            try
            {
                XDocument doc = XDocument.Load(StoredDataFile);
                XElement root = doc.Root;
                var values = doc.Root.Elements(tagToRead).Select(n => n.Value);
                
                //iterate through and get name and value to add to dictionary
                foreach (var value in values)
                {
                    string[] split = value.Split(',');
                    outDict.Add(split[0], Convert.ToBoolean(split[1]));
                }   
                return outDict;

            }
            catch (Exception ex)
            {
                Autodesk.Revit.UI.TaskDialog.Show("Read XML Error", ex.Message);
                return null; 
            }

        }

public static Dictionary<string, bool> ReadFromXML(string tagToRead)
        {
            Dictionary<string, bool> outDict = new Dictionary<string, bool>();
            //look for the tag tagtoread in the XML tree, then return all values in that tag as a dictionary
            try
            {
                XDocument doc = XDocument.Load(StoredDataFile);
                XElement root = doc.Root;
                var values = doc.Root.Elements(tagToRead).Select(n => n.Value);
                
                //iterate through and get name and value to add to dictionary
                foreach (var value in values)
                {
                    string[] split = value.Split(',');
                    outDict.Add(split[0], Convert.ToBoolean(split[1]));
                }   
                return outDict;

            }
            catch (Exception ex)
            {
                Autodesk.Revit.UI.TaskDialog.Show("Read XML Error", ex.Message);
                return null; 
            }

        }

I get an error Pref is an unexpected token. The expected token is = Line 2, position 20.

❔ Properties.Settings.Default producing different stored values when called from different winForms

Environment (Autodesk Revit API) I am using Properties.Settings.Default and can update, reload or save the appropriate setting happily, however I am getting different values when trying to load the property from a different win form that setting was saved in. For example, the following (generic names used) Properties.Settings.Default.Setting1 = "default"; in winform1 I save a string: Properties.Settings.Default.Setting1 = "string"; Then I save it. When reopening the winform I use the reload method. I then correctly see string instead of default, in the example. The setting was successfully updated. However if I try to view this setting outside of winform1, say winform2, I only see the default setting applied from inside VS. Anyone have an idea why this could be happening or directions to fix?

✅ Win Form Event Handlers question

Hi, I was just wondering if there is an event handler when the win form is idle that I can then run code in. I am looking to use it as a modeless form alongside the Revit API to sync a 2D drawing and a 3D model view together. I am currently using the Revit API Idle event, however I want to change this method of functionality to be toggled via a button in a win form as it adds unnecessary load to the Revit application. Once alternative method I thought about was running on a mouse move event, or if there is some kind of user input.

❔ different variable type depending on condition of IF statement

Hi there, how would I go about having a different type on a variable with the same name, for later use? This is required for use in my code later on within the Autodesk RevitAPI

var elmFilter = null;
if (FilterSelected == 0)
{
   Helpers.ElementFilterTerminals elmFilter = new Helpers.ElementFilterTerminals();
}
if (FilterSelected == 1)
{
   Helpers.ElementFilterDuctwork elmFilter = new Helpers.ElementFilterDuctwork();
}

//later on...

pickedRef = sel.PickObject(ObjectType.PointOnElement, elmFilter, "Pick the elements to be updated.");

var elmFilter = null;
if (FilterSelected == 0)
{
   Helpers.ElementFilterTerminals elmFilter = new Helpers.ElementFilterTerminals();
}
if (FilterSelected == 1)
{
   Helpers.ElementFilterDuctwork elmFilter = new Helpers.ElementFilterDuctwork();
}

//later on...

pickedRef = sel.PickObject(ObjectType.PointOnElement, elmFilter, "Pick the elements to be updated.");

in my helpers class:

        public class ElementFilterTerminals : ISelectionFilter
        {
            public bool AllowElement(Element e)
            {
                //TO-DO: Add Magicad Family for end caps to this.
                return (e.Category.Id.IntegerValue.Equals(
                  (int)BuiltInCategory.OST_DuctTerminal)) ||
                (e.Category.Id.IntegerValue.Equals(
                  (int)BuiltInCategory.OST_MechanicalEquipment));
            }

            }
        }

            public bool AllowReference(Autodesk.Revit.DB.Reference r, XYZ p)
            {

                return (r.ElementReferenceType == ElementReferenceType.REFERENCE_TYPE_SURFACE);
            }
        }

❔ ✅ remove from list (RevitAPI)

I have started learning C# today. Please bare with me 🙂 I am trying to remove an element from an list if its existing, otherwise add it.

pickedRef = sel.PickObject(ObjectType.PointOnElement, elmFilter, "Pick the elements to be updated.");

// create list and add/remove depending on action with element
List<ElementId> selectId = new List<ElementId>();
Color overrideColor = new Color(255, 182, 193);
ElementId elmId = pickedRef.ElementId;

if (selectId.Contains(elmId))
{
  OverrideColour(uiApp, elmId, overrideColor, true);
  selectId.Remove(elmId);
  TaskDialog.Show("AA", "T");
}
else
{
  OverrideColour(uiApp, elmId, overrideColor, false);
  selectId.Add(elmId);
  TaskDialog.Show("AA", "F");
}

pickedRef = sel.PickObject(ObjectType.PointOnElement, elmFilter, "Pick the elements to be updated.");

// create list and add/remove depending on action with element
List<ElementId> selectId = new List<ElementId>();
Color overrideColor = new Color(255, 182, 193);
ElementId elmId = pickedRef.ElementId;

if (selectId.Contains(elmId))
{
  OverrideColour(uiApp, elmId, overrideColor, true);
  selectId.Remove(elmId);
  TaskDialog.Show("AA", "T");
}
else
{
  OverrideColour(uiApp, elmId, overrideColor, false);
  selectId.Add(elmId);
  TaskDialog.Show("AA", "F");
}

I seem too only be able to run whats in the else, and never if the list contains the element. The logic works, as I have it in python already:

ref = uidoc.Selection.PickObject(ObjectType.Element, 'Pick elements in the desired order (re-select to Remove), hit ESC to stop picking.')
e_id = ref.ElementId
if e_id not in selectId:
    overridecolor(e_id)
    selectId.append(e_id)
else:
    overridecolor(e_id, True)
    selectId.pop(selectId.index(e_id))

ref = uidoc.Selection.PickObject(ObjectType.Element, 'Pick elements in the desired order (re-select to Remove), hit ESC to stop picking.')
e_id = ref.ElementId
if e_id not in selectId:
    overridecolor(e_id)
    selectId.append(e_id)
else:
    overridecolor(e_id, True)
    selectId.pop(selectId.index(e_id))
