语法

声明
<SharePointPermissionAttribute(SecurityAction.InheritanceDemand, ObjectModel:=True)> _
<SharePointPermissionAttribute(SecurityAction.Demand, ObjectModel:=True)> _
Public Class DbEntityInstanceEnumerator
    Implements IEntityInstanceEnumerator
用法
Dim instance As DbEntityInstanceEnumerator

[SharePointPermissionAttribute(SecurityAction.InheritanceDemand, ObjectModel=true)] 
[SharePointPermissionAttribute(SecurityAction.Demand, ObjectModel=true)] 
public class DbEntityInstanceEnumerator : IEntityInstanceEnumerator

备注

The Runtime namespace contains classes and base classes that offer an intuitive, object-oriented interface to Business Data Catalog client applications. It abstracts the underlying data sources and insulates the clients from having to learn application-specific coding paradigms and allows them to access all business applications in a single, simplified way. It is because of the Runtime namespace that calling a method on an SAP application feels just the same as calling a method on Siebel or executing a query in SQL. You should work with the IEntityInstanceEnumerator instead of working directly with the system-specific DbEntityInstanceEnumerator.
