EdmRelationshipAttribute Class

Defines a relationship between two entity types based on an association in the conceptual model.

System.Object
  System.Attribute
    System.Data.Objects.DataClasses.EdmRelationshipAttribute

Namespace:  System.Data.Objects.DataClasses
Assembly:  System.Data.Entity (in System.Data.Entity.dll)

[AttributeUsageAttribute(AttributeTargets.Assembly, AllowMultiple = true)]
public sealed class EdmRelationshipAttribute : Attribute

The EdmRelationshipAttribute type exposes the following members.

  NameDescription
Public propertyIsForeignKeyGets a Boolean value that indicates whether the relationship is based on the foreign key value.
Public propertyRelationshipNameName of the relationship.
Public propertyRelationshipNamespaceNameThe namespace for the relationship.
Public propertyRole1MultiplicityMultiplicity at one end of the relationship.
Public propertyRole1NameName of the role at one end of the relationship.
Public propertyRole1TypeType of the entity at one end of the relationship.
Public propertyRole2MultiplicityMultiplicity at the other end of the relationship.
Public propertyRole2NameName of the role at the other end of the relationship.
Public propertyRole2TypeType of the entity at the other end of the relationship.
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)

  NameDescription
Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

  NameDescription
Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

This attribute is applied at the assembly level with one instance for each association. There can be multiple attributes of this type in an assembly.

The details for the role of an entity type in a particular association should match the association defined in the conceptual schema.

An association does not define any ordering for the roles. This means that properties that define the related ends of an association can be defined in any order.
