DataSourceKeyNameAttribute Class

Defines an attribute that associates an Entity subclass with a DataSourceKeyName.

Syntax

Visual Basic
C#

'Declaration
 
<AttributeUsageAttribute(ValidOn=AttributeTargets.Class, 
   AllowMultiple=True, 
   Inherited=True)>
Public NotInheritable Class DataSourceKeyNameAttribute 
   Inherits System.Attribute
   Implements System.Runtime.InteropServices._Attribute

'Usage
 
Dim instance As DataSourceKeyNameAttribute

[AttributeUsage(ValidOn=AttributeTargets.Class, 
   AllowMultiple=true, 
   Inherited=true)]
public sealed class DataSourceKeyNameAttribute : System.Attribute, System.Runtime.InteropServices._Attribute

Remarks

This attribute is auto-generated by the Object Mapper on each Entity class using the name of the data source key specified for the Entity Model. It is also generated on each EntityManager partial class to indicate which datasource keys are present within the EntityManager. Multiple datasource key attributes may be marked on a single EntityManager because an EntityManager may consist of multiple partial classes each representing a different data source. At run time, the actual data source key used is resolved based on the DataSourceKeyName attribute and the data source extension used by the Entity Manager.
