Bug #23268 System.FormatException when invoking procedure with ENUM input parameter

Description:
System.FormatException is generated when invoking a stored procedure that is defined with an IN parameter of ENUM type.  The error occurs regardless of whether the input parameter is a string or an integer data type.

One possible workaround for affected users is to redefine the stored procedure to use a different data type for the IN paramter.

The stack trace is below:

How to repeat:
Test case attached.

Create a procedure with an ENUM IN parameter.  Try to invoke this stored procedure using Connector/NET 5.0.1-beta.

Suggested fix:
Eliminate System.FormatException when using ENUM input parameters.
