Session.GetObjectsFromSprocParametrized(XPClassInfo, String, SprocParameter[]) Method

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

Namespace: DevExpress.Xpo

Assembly: DevExpress.Xpo.v21.1.dll


public ICollection GetObjectsFromSprocParametrized(
    XPClassInfo classInfo,
    string sprocName,
    params SprocParameter[] 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.

parameters DevExpress.Xpo.DB.SprocParameter[]

An array of SprocParameter objects specifying 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. 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.

This method takes named parameters. The parameter order is arbitrary. The SprocParameter.Direction property should be set to Output for out parameters. Based on the current ADO.NET provider, the data type (SprocParameter.DbType), scale (SprocParameter.Scale) and precision (SprocParameter.Precision) may be required.


The GetObjectsFromSprocParametrized method throws an exception if classInfo members include any of the following:

  • 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.
