Retrieve Expression attribute via Column

[vermw]

Dear all,
I'm writing a script that loops over all columns in the model, checks if the column type is Calculated and then gets its Expression. Something like this:
foreach (var m in Model.AllColumns) { if(m.Type == ColumnType.Calculated) { if (m.Expression.Contains("dog")){ Info(m.Name); } } }

Problem is that the Columns class doesn't have an expression. Though when I do a ToString() on the column (m.ToString()), then it shows me "TabularEditor.TOMWrapper.CalculatedColumn", so it knows it's a calculated column, yet treats it as column.

Anyway, what is the appropriate way to retrieve an expression if you have the column?

Thanks!

I found a solution via:
foreach (var t in Model.Tables) { foreach (var cc in t.CalculatedColumns) { if (cc.Expression.Contains("dog")) { Info(t.Name + " " + cc.Name); } } }
It requires 2 loops instead of 1, so less ideal, but it does get the job done. Still interested if there would be an approach using the Model.AllColumns from my original post.
