Syntax

Visual Basic
C#

'Declaration
 
Public Function New( _
   ByVal role1Type As Type, _
   ByVal role2Type As Type, _
   ByVal role1Multiplicity As Multiplicity, _
   ByVal role2Multiplicity As Multiplicity, _
   ByVal role1OnDeleteMode As OnDeleteMode, _
   ByVal role2OnDeleteMode As OnDeleteMode, _
   ByVal relationName As String, _

'Usage
 
Dim role1Type As Type
Dim role2Type As Type
Dim role1Multiplicity As Multiplicity
Dim role2Multiplicity As Multiplicity
Dim role1OnDeleteMode As OnDeleteMode
Dim role2OnDeleteMode As OnDeleteMode
Dim relationName As String
Dim shouldUpdateMetadataStore As Boolean
 
Dim instance As New EntityRelation(role1Type, role2Type, role1Multiplicity, role2Multiplicity, role1OnDeleteMode, role2OnDeleteMode, relationName, shouldUpdateMetadataStore)

public EntityRelation( 
   Type role1Type,
   Type role2Type,
   Multiplicity role1Multiplicity,
   Multiplicity role2Multiplicity,
   OnDeleteMode role1OnDeleteMode,
   OnDeleteMode role2OnDeleteMode,
   string relationName,
   bool shouldUpdateMetadataStore
)

Parameters

role1Type: Role1 entity type
role2Type: Role2 entity type
role1Multiplicity: Multiplicity of the role1 end
role2Multiplicity: Multiplicity of the role2 end
role1OnDeleteMode: Action to take upon delete of a role1 entity
role2OnDeleteMode: Action to take upon delete of a role2 entity
relationName: The non-namespace qualified name representing the role1/role2 relation.
shouldUpdateMetadataStore

Exceptions

Exception	Description
System.ArgumentException	Relation names must be universally unique.

Remarks

EntityRelations are automatically generated by the DevForce Object Mapping tool, and you will not usually need to construct additional instances. You can retrieve one or more EntityRelations using one of the GetEntityRelations overloads.

Note that the role1Type and role2Type cannot necessarily be inferred from role1Properties and role2Properties because of type inheritence. For example, the role1Type may be a subclass of the role1Properties[0].EntityType.

The relation name provided here should not be namespace-qualified. Namespace qualifiers are added automatically at run time to ensure that relation names are unique across all models loaded.

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
