AutoCAD .NET: Iterate Through Visual Style Dictionary

We need to iterate through the visual style dictionary of the current database from time to time. Here is some succinct and good code in C# to do so.

[CommandMethod("VisualStyleIterator")]
public static void VisualStyleIterator_Method()
{
    Database database = HostApplicationServices.WorkingDatabase;
    using (Transaction transaction = database.TransactionManager.StartTransaction())
    {
        DBDictionary dbDictionary = (DBDictionary)transaction.GetObject(database.VisualStyleDictionaryId, OpenMode.ForRead);
        foreach (DBDictionaryEntry dictEntry in dbDictionary)
        {
            DBVisualStyle entry = (DBVisualStyle)transaction.GetObject(dictEntry.Value, OpenMode.ForRead);

            //TODO: Access to the entry object
            MgdAcApplication.DocumentManager.MdiActiveDocument.Editor.WriteMessage(string.Format("\nVisual style name: {0}", entry.Name));
        }

        transaction.Commit();
    }
}

If the command is run, something like the following may be printed out to the command line window.

Command: VisualStyleIterator
Visual style name: 2dWireframe
Visual style name: 3D Hidden
Visual style name: 3dWireframe
Visual style name: Basic
Visual style name: Brighten

is there a way in C# to capture the current visualstyle so i can use it later to reset the visualstyle back.

Hi McDiver, the Viewport.VisualStyleId Property should be what you are looking for. Since visual style is viewport dependant instead of database or document, no system variable is used to store the current visual style setting. The Database.ViewportTableId can give you the view port table then you can retrieve the *Active viewport from it. In case you’d like to get the display name of the visual style as shown by the UI, you can open the DBVisualStyle and get its Name as demonstrated in the post here.
