You can see that I highlighted ProjectListModel.rolePMA. It is null for every list item. So I want to remove it from the list. Not the whole row just that member of every row. Is it possible to do this? The web page is going to display a grid from these query results and there is no need to have a column in the grid that is always null. My idea was to convert the list to a datatable and then I think I know how to process the datatable and remove the column (I think it would be a column) and convert the datatable back to a list. But I wanted to ask if this approach is correct and/or is there a better way? Thank you!]]> Sorry about the stupid title. I don't know what the "something" is.

I'm working with a web application so I run a database query asyncronously and get back a datatype "var" like so:
var data = await connection.QueryAsync<T>(sql);
