Session.GetObjectsFromSproc(XPClassInfo, List<XPMemberInfo>, String, OperandValue[]) Method

Executes a stored procedure and returns its result set as a collection of non-persistent objects.

Namespace: DevExpress.Xpo

Assembly: DevExpress.Xpo.v21.2.dll


public ICollection GetObjectsFromSproc(
    XPClassInfo classInfo,
    List<XPMemberInfo> members,
    string sprocName,
    params OperandValue[] 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.

members List<XPMemberInfo>

Specifies object members mapped to columns in the resulting set. The order of list elements should correspond to the order of the resulting set columns.

sprocName String

A String value that specifies the stored procedure’s name.

parameters OperandValue[]

An array of OperandValue objects representing parameters to pass to the stored procedure.


Type Description

A collection of non-persistent classInfo objects instantiated with data obtained via the specified stored procedure.


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 based on the mapping information passed as the members parameter. Note that classInfo should represent a non-persistent class decorated with a NonPersistentAttribute.


The GetObjectsFromSproc method throws an exception if the members list includes any of the following classInfo members:

  • A property that is not defined within the classInfo object.
  • A struct type member.
  • A reference to a class with a struct type member.
  • A collection used in object relations.
