InvalidOperationException

The specified column does not contain a 64-bit signed integer value.

No conversions are performed; therefore, the data retrieved must already be an Int64 or coercible to an Int64.

Call IsDBNull to see if there are null values before calling this method.

The following example displays the contents of the column numbered 2 within the passed-in DataTableReader. If the value the column within a particular row is null, the code displays the text <NULL>.
