Performs a query and returns the results as a ResultSet object.
Synopsis:
ResultSet QueryObjects(string sessionId, string query, string criteria, string sortBy, string attributes, string options)
Return Value:
Result set of the query as a ResultSet object. If the set contains objects to which the user does not have rights to, only object ID is returned for those. While this function returns the same information as QueryObjectsAsXml, the information is contained in objects derived from the GenericElement superclass.
Supported classes and their properties are as follows:
ResultSet
Root object returned by the QueryObjects function call
ResultSet properties:
•int TotalResultsReturned: Number of objects matching the query
•GenericElement[] ChildElements: Array containing all the objects matching the query. Currently all the objects in this array are of type ResultObject
ResultObject
Container for all the attributes of a single result object.
ResultObject properties:
•string Id: ID of the object
•GenericElement[] ChildElements: Array containing all the values of the queried attributes. Currently all the objects in this array are of type Property
Property
Container for the value of a single attribute of a single result object.
Property properties:
•string Name: Name of the attribute
•string Value: Value of the attribute
•string ValueType: XML type of attribute's value
•ValueElement[] Attributes: Array containing additional information about the property
•GenericElement[] ChildElements: Array containing additional information about more complex attribute values. Currently all the objects in this array are of type Element
Element
Generic container for miscellaneous named information
Element properties:
•string Name: Name of the element
•string Value: Value of the element
•string ValueType: XML type of element's value
•ValueElement[] Attributes: Array containing additional information about the element
•GenericElement[] ChildElements: Array containing additional related sub-objects of the element
ValueElement
Simple name+value container
ValueElement Properties:
•string Name: Name
•string Value: Value
•string ValueType: XML type of the value
•GenericElement[] ChildElements: Array containing additional related sub-objects. Currently always empty
Parameters:
sessionId: String. ID of an authenticated session.
query: String. The actual query. See the Query Syntax section for syntax information.
criteria: String.
sortBy: String.
attributes: String. Comma-separated list of attributes that are included in the results.
options: String. Additional options for the query.
Example Procedure:
ServiceClient client = new ServiceClient("WSHttpBinding_IService");

ResultSet result = client.QueryObjects(sessionId, "[SC.1].SubObjects", "", "", "", "");
client.LogOff(sessionId);
client.Close();
