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

NameDescription
System_CAPS_pubpropertyIsForeignKey

Gets a Boolean value that indicates whether the relationship is based on the foreign key value.

System_CAPS_pubpropertyRelationshipName

Name of the relationship.

System_CAPS_pubpropertyRelationshipNamespaceName

The namespace for the relationship.

System_CAPS_pubpropertyRole1Multiplicity

Multiplicity at one end of the relationship.

System_CAPS_pubpropertyRole1Name

Name of the role at one end of the relationship.

System_CAPS_pubpropertyRole1Type

Type of the entity at one end of the relationship.

System_CAPS_pubpropertyRole2Multiplicity

Multiplicity at the other end of the relationship.

System_CAPS_pubpropertyRole2Name

Name of the role at the other end of the relationship.

System_CAPS_pubpropertyRole2Type

Type of the entity at the other end of the relationship.

System_CAPS_pubpropertyTypeId

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

NameDescription
System_CAPS_pubmethodEquals(Object)

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)

System_CAPS_pubmethodGetHashCode()

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodIsDefaultAttribute()

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)

System_CAPS_pubmethodMatch(Object)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfoCount(UInt32)

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides 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.
