Hello, thank you for your response regarding this issue. I was able to obtain the properties I needed; however, with my current code, which I adapted to use your provided method, the software is crashing, and I am unable to identify the problem. Can you take a look?
It performs a simple operation, in theory, it should obtain the value of the properties:
And check if the value of each one exists in my list of strings (rowValues).
My code:
public static void IsolateSelectedObjects(List<string> rowValues)
{
try
{
Document acDoc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
if (acDoc != null)
{
acDoc.LockDocument();
Database db = acDoc.Database;
using (Transaction tr = db.TransactionManager.StartTransaction())
{
BlockTable bt = (BlockTable)tr.GetObject(db.BlockTableId, OpenMode.ForRead);
BlockTableRecord btr = (BlockTableRecord)tr.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite);
foreach (ObjectId id in btr)
{
try
{
Entity entity = tr.GetObject(id, OpenMode.ForWrite) as Entity;
if (entity == null)
{
continue;
}
bool found = false;
bool shouldBeVisible = false;
if (entity is IsoArrowSymbol || entity is IsoSphereSymbol || entity is IsoStartPointSymbol)
{
//MessageBox.Show("Entrou no bloco de verificação de IsoArrowSymbol, IsoSphereSymbol ou IsoStartPointSymbol");
try
{
IDictionary<string, object> properties = GetOPMProperties(id);
var propertyDictionary = new Dictionary<string, string>();
if (properties != null && properties.Count > 0)
{
Thread.Sleep(1500);
//MessageBox.Show("Propriedades obtidas com sucesso.");
foreach (var property in properties)
{
string key = property.Key;
string value = string.Empty;
try
{
value = property.Value?.ToString();
//MessageBox.Show($"Propriedade: {key} = {value}");
}
catch (System.Exception ex)
{
MessageBox.Show($"Erro ao converter valor da propriedade para string: {ex.Message}");
continue;
}
if (key == "Line Number Tag" || key == "Service" || key == "Spec")
{
if (!string.IsNullOrEmpty(value))
{
if (rowValues.Contains(value))
{
shouldBeVisible = true;
found = true;
//MessageBox.Show("Encontrou a propriedade necessária e está visível.");
break;
}
}
}

}
