Removing All/1 Property from the DatabaseSummaryInfoBuilder CustomPropertyTable

[Anonymous]

I'm attempting to remove Custom properties from a drawing like so

public static void RemoveCustomProperty(this Database db, string key)
        {
            DatabaseSummaryInfoBuilder infoBuilder = new DatabaseSummaryInfoBuilder(db.SummaryInfo);
            IDictionary custProps = infoBuilder.CustomPropertyTable;
            custProps.Remove(key);
        }

and 

public static void RemoveCustomProperties(this Database db)
        {
            DatabaseSummaryInfoBuilder infoBuilder = new DatabaseSummaryInfoBuilder(db.SummaryInfo);
            IDictionary custProps = infoBuilder.CustomPropertyTable;
            custProps.Clear();
        }

However they don't seem to work and I keep running into a deadend.

Am i missing something silly?? - Thanks for any help

Hi,

You need to overwrite the summary info after editing the dictionary.

        public static void RemoveCustomProperty(this Database db, string key)
        {
            DatabaseSummaryInfoBuilder infoBuilder = new DatabaseSummaryInfoBuilder(db.SummaryInfo);
            IDictionary custProps = infoBuilder.CustomPropertyTable;
            custProps.Remove(key);
            db.SummaryInfo = infoBuilder.ToDatabaseSummaryInfo();
        }

        public static void RemoveCustomProperties(this Database db)
        {
            DatabaseSummaryInfoBuilder infoBuilder = new DatabaseSummaryInfoBuilder(db.SummaryInfo);
            IDictionary custProps = infoBuilder.CustomPropertyTable;
            custProps.Clear();
            db.SummaryInfo = infoBuilder.ToDatabaseSummaryInfo();
        }
