	成员名称	说明
	In	The Business Data Catalog instantiates the parameter and passes it to the system.
	InOut	System instantiates the parameter and passes it to the Business Data Catalog (corresponds to the Microsoft Visual C# ref keyword). The backend uses the parameter and overwrites it with a new value that the Business Data Catalog will marshal back, as long as this Parameter is the 'ReturnParameter' for the MethodInstance that is being executed.
	Out	The Business Data Catalog does nothing to this parameter. The system, may initialize it before returning it to the Business Data Catalog. This corresponds to the C# out keyword. The Business Data Catalog will marshal it back to the client if this Parameter is defined as the ReturnParameter in the MethodInstance being executed.
	Return	The system initializes the parameter and passes it to the Business Data Catalog as the return value of a method.
