Check for a column in the DataReader OR do not disable the debugger for specific exceptions

Question

I have a code that looks like this:

  //System.Data.IDataRecord dr
  try
  {
       Consolidated = Utility.NullConvert.ToBool(dr[Constants.Data.Columns.cConsolidated], false);
  }
  catch (IndexOutOfRangeException) { } //swallow

I do not know if a consolidated column will be present in the datareader, so I do this for verification. It works great (a bit hacky).

When I attach a debugger, it breaks into this when it throws an exception. Extremely annoying.

Is there a better way to write this code; or is there some kind of Visual Studio method telling it to ignore the exception and not interrupt (but only right here, and not everywhere).
