Lets examine the problem a bit more, because I was as perplexed as you
were that a conversion from int to int would throw that exception.
What is happening here is that "reader.GetOrdinal
("RealContentItemId")" returns an integer.
And here is the problem: the returned int is used as the ColumnValue
*key* whose value happens to be something different.
Am not a System.Data expert, but this is either a bug on the original
runtime, or there is a miss-conception in the
