Title
Body
Is there a way to see if a field exists in an IDataReader-based object w/o just checking for an IndexOutOfRangeException? In essence, I have a method that takes an IDataReader-based object and creates a strongly-typed list of the records. In 1 instance, one data reader has a field that others do not. I don't really want to rewrite all of the queries that feed this method to include some form of this field if I don't have to. The only way I have been able to figure out how to do it so far is to throw the 1 unique field into a try/catch block as shown below. try { tmp.OptionalField = reader["optionalfield"].ToString(); } catch (IndexOutOfRangeException ex) { //do nothing } Is there a cleaner way short of adding the "optional field" to the other queries or copying the loading method so 1 version uses the optional field and the other doesn't? I'm in the 2.0 framework also.
