how can i exclude some of the attributes at depth 2?

i have a list that i want to hide 3 columns in the output. How can i update the Util.HorizontalRun(true, TradeObjectsFiltered).Dump(exclude: ?????" to factor the elements at depth 2 and only ignore some of the columns.

Write a ToDump method in the query:

static object ToDump (object input)
{
    if (input is Event e)
        return new { e.Prop1, e.Prop2, ... };  // Properties that you want

    return input;
}

Alternatively:

static object ToDump (object input)
{
    if (input is Event e)
        return Util.ToExpando (e, include:"...");

    return input;
}

or:

static object ToDump (object input)
{
    if (input is Event e)
        return Util.ToExpando (e, exclude:"...");

    return input;
}

You can also programmatically add or remove properties from the expando, should that be easier.

Make sure the query type is set to "C# Program", otherwise the ToDump method will not work.
