The type initializer for "Oracle.DataAccess.Client.OracleConnection" throws an exception.

The type initializer for "Oracle.DataAccess.Client.OracleConnection" throws an exception.

Was plagued by this problem for a long time, and finally found the reason :

The original version of the Oracle client that was natively installed is inconsistent with the server.

Workaround:

The following DLL files can be referenced, the DLL is divided into two versions, Windows7 32-bit System pro-test, regardless of the installation of Oracle client, can be used.

Version One: http://download.csdn.net/detail/zhzhx0318/9120651

Version two: http://download.csdn.net/detail/zhzhx0318/9120659
