) As ICollection

Parameters

Name	Type	Description
classInfo	XPClassInfo	An XPClassInfo object which contains the metadata information on a non-persistent class corresponding to the stored procedure’s result set. The class must be decorated with NonPersistentAttribute.
sprocName	String	A String value that specifies the stored procedure’s name.

Remarks

This method performs the following:

• Executes the specified stored procedure with parameters and obtains the result as a result set.
• Populates a collection with classInfo objects that are instantiated with the result set’s data. The type and the order of classInfo members should exactly match the result set’s columns. Note that classInfo should represent a non-persistent class decorated with a NonPersistentAttribute.
