Parameters

typeName: String

Name of the type of the object to enumerate.

items: Object[]

The set of items to enumerate, specified as strings where named items are available, otherwise as indexes. In cases in which a data provider does not support items filtering, this parameter is ignored.Not supported in Visual Studio 2005.

restrictions: Object[]

A set of filtering restrictions to apply to the set of returned objects.

sort: String

A sort string, which follows syntax for the SQL Server ORDER BY clause. The actual sort order should be source-based; that is, if the client is English and the source is Chinese, the sort should be applied in Chinese.Not supported in Visual Studio 2005.

parameters: Object[]

An array whose contents are defined by the given implementation of EnumerateObjects(String, Object[], Object[], String, Object[]), and which is specified by the Data Object Support XML file. Information supplied in this parameter can be used to provide extra data indicating how to perform the enumeration, allowing implementations of this method to be more data driven.
