NameDescription
System_CAPS_pubmethod EdmRelationshipAttribute

Creates an instance of the EdmRelationshipAttribute class.

System_CAPS_pubmethod EdmRelationshipAttribute

Initializes a new instance of the EdmRelationshipAttribute class.

NameDescription
System_CAPS_pubproperty

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

System_CAPS_pubproperty

Name of the relationship.

System_CAPS_pubproperty

The namespace for the relationship.

System_CAPS_pubproperty

Multiplicity at one end of the relationship.

System_CAPS_pubproperty

Name of the role at one end of the relationship.

System_CAPS_pubproperty

Type of the entity at one end of the relationship.

System_CAPS_pubproperty

Multiplicity at the other end of the relationship.

System_CAPS_pubproperty

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

System_CAPS_pubproperty

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

System_CAPS_pubproperty

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

NameDescription
System_CAPS_pubmethod Equals

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_pubmethod GetHashCode

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

System_CAPS_pubmethod GetType

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

System_CAPS_pubmethod IsDefaultAttribute

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_pubmethod Match

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

System_CAPS_pubmethod ToString

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

NameDescription
System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetIDsOfNames

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

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfo

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

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfoCount

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

System_CAPS_pubinterface System_CAPS_privmethod _AttributeInvoke

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.
