How do rename and remove columns in a MS SQL table?

I'm using the Server Management Objects library to alter a table.

My code for adding a column works fine, but whenever I try to rename a column, I get "SetName failed for Column '[columnName]'."

Likewise, my attempts to remove a column are met with "The Column '[columnName]' does not exist on the server."

All I'm doing are:

      tbl.Columns[oldName].Name = newName;


Another error that I've gotten when I attempt to remove columns is "You cannot perform operation Remove on an object in state Existing."

If all you want is to remove a column name from a table, why not simply do this:

And if your intention is to rename a column from old to new, for instance, this will do it:

sp_RENAME Yourtable.OldName', 'NewName' , 'COLUMN'

That's it
Is it possible that I misunderstood what you are trying to do?
