Where is type [Oracle.DataAccess.Client.OracleBulkCopy]?

问题

I tried

[System.Reflection.Assembly]::LoadWithPartialName("Oracle.DataAccess") 
$bulkCopy = new-object Oracle.DataAccess.Client.OracleBulkCopy $oraClientConnString

and got

GAC    Version        Location

Cf. OracleBulkCopy Class

What is missing?

回答1:

Maybe you're using an older version of Oracle? I see documentation for this class on Oracle for 11g or later.

http://download.oracle.com/docs/html/E10927_01/OracleBulkCopyClass.htm

Oracle.DataClient.dll is the containing assembly in the above documentation.

Try this:

ps> $a = [reflection.assembly]::loadwithpartialname("oracle.dataaccess")
ps> $a.getexportedtypes() | where { $_.fullname -like "*bulk*" }
