)
Parameters
field (Int32)
Specifies the field of the Record to get.
filePath (String)

Remarks

This method is capable of directly extracting substorages. To do so, first select both the `Name` and `Data` column of the `_Storages` table, then get the stream of the `Data` field. However, substorages may only be extracted from a database that is open in read-only mode.

Win32 MSI API: MsiRecordReadStream

Exceptions
Exception Condition
ArgumentOutOfRangeException The field is less than 0 or greater than the number of fields in the Record.
NotSupportedException Attempt to extract a storage from a database open in read-write mode, or from a database without an associated file path
