Properties

Name Description
ClrType

Gets the type of value that this property-like object holds.

(Inherited from IReadOnlyPropertyBase)
DeclaringEntityType

Gets the entity type that this navigation property belongs to.
DeclaringType

Gets the type that this property-like object belongs to.

(Inherited from IReadOnlyPropertyBase)
FieldInfo

Gets the FieldInfo for the underlying CLR field for this property-like object. This may be null for shadow properties or if the backing field is not known.

(Inherited from IReadOnlyPropertyBase)
Inverse

Gets the inverse navigation.
IsCollection

Gets a value indicating whether the navigation property is a collection property.
IsEagerLoaded

Gets a value indicating whether this navigation should be eager loaded by default.
Item[String]

Gets the value of the annotation with the given name, returning null if it does not exist.

(Inherited from IReadOnlyAnnotatable)
LazyLoadingEnabled

Determines whether this navigation should lazy-load if lazy-loading is enabled and a mechanism for lazy-loading has been configured in the model.

(Inherited from IReadOnlyNavigationBase)
Name

Gets the name of this property-like object.

(Inherited from IReadOnlyPropertyBase)
PropertyInfo

Gets the PropertyInfo for the underlying CLR property for this property-like object. This may be null for shadow properties or if mapped directly to a field.

(Inherited from IReadOnlyPropertyBase)
Sentinel

Gets the sentinel value that indicates that this property is not set.

(Inherited from IReadOnlyPropertyBase)
TargetEntityType

Gets the entity type that this navigation property will hold an instance(s) of.

Methods

Name Description
AddRuntimeAnnotation(String, Object)

Adds a runtime annotation to this object. Throws if an annotation with the specified name already exists.

(Inherited from IAnnotatable)
AnnotationsToDebugString(Int32)

Gets the debug string for all annotations declared on the object.

(Inherited from IReadOnlyAnnotatable)
FindAnnotation(String)

Gets the annotation with the given name, returning null if it does not exist.

(Inherited from IReadOnlyAnnotatable)
FindRuntimeAnnotation(String)

Gets the runtime annotation with the given name, returning null if it does not exist.

(Inherited from IAnnotatable)
FindRuntimeAnnotationValue(String)

Gets the value of the runtime annotation with the given name, returning null if it does not exist.

(Inherited from IAnnotatable)
GetAnnotation(String)

Gets the annotation with the given name, throwing if it does not exist.

(Inherited from IReadOnlyAnnotatable)
GetAnnotations()

Gets all annotations on the current object.

(Inherited from IReadOnlyAnnotatable)
GetCollectionAccessor()

Gets the IClrCollectionAccessor for this navigation property, if it's a collection navigation.
GetCurrentValueComparer()

Gets a IComparer<T> for comparing values in tracked IUpdateEntry entries.

(Inherited from IPropertyBase)
GetFieldName()

Gets the name of the backing field for this property, or null if the backing field is not known.

(Inherited from IReadOnlyPropertyBase)
GetGetter()

Gets a IClrPropertyGetter for reading the value of this property.

(Inherited from IPropertyBase)
GetIndex()

Gets the property index for this property.

(Inherited from IPropertyBase)
GetMemberInfo(Boolean, Boolean)

Gets the PropertyInfo or FieldInfo that should be used to get or set a value for the given property.

(Inherited from IPropertyBase)
GetOrAddRuntimeAnnotationValue<TValue,TArg>(String, Func<TArg,TValue>, TArg)

Gets the value of the runtime annotation with the given name, adding it if one does not exist.

(Inherited from IAnnotatable)
GetPropertyAccessMode()

Gets the PropertyAccessMode being used for this property-like object.

(Inherited from IReadOnlyPropertyBase)
GetRuntimeAnnotations()

Gets all the runtime annotations on the current object.

(Inherited from IAnnotatable)
IsIndexerProperty()

Gets a value indicating whether this is an indexer property. An indexer property is one that is accessed through an indexer on the entity class.

(Inherited from IReadOnlyPropertyBase)
IsShadowProperty()

Gets a value indicating whether this is a shadow property. A shadow property is one that does not have a corresponding property in the entity class. The current value for the property is stored in the ChangeTracker rather than being stored in instances of the entity class.

(Inherited from IReadOnlyPropertyBase)
RemoveRuntimeAnnotation(String)

Removes the given runtime annotation from this object.

(Inherited from IAnnotatable)
SetIsLoadedWhenNoTracking(Object)

Calls SetLoaded(Object, String, Boolean) for a INavigationBase to mark it as loaded when a no-tracking query has eagerly loaded this relationship.
SetRuntimeAnnotation(String, Object)

Sets the runtime annotation stored under the given key. Overwrites the existing annotation if an annotation with the specified name already exists.

(Inherited from IAnnotatable)

Explicit Interface Implementations

Name Description
IPropertyBase.GetPropertyAccessMode()

Gets the PropertyAccessMode being used for this property. null indicates that the default property access mode is being used.

IReadOnlyPropertyBase.IsShadowProperty()

Gets a value indicating whether this is a shadow property. A shadow property is one that does not have a corresponding property in the entity class. The current value for the property is stored in the ChangeTracker rather than being stored in instances of the entity class.

(Inherited from IReadOnlyNavigationBase)

Extension Methods

Name Description
AnnotationsToDebugString(IAnnotatable, Int32)

Gets the debug string for all annotations declared on the object.
GetAnnotation(IAnnotatable, String)

Gets the annotation with the given name, throwing if it does not exist.
SetIsLoadedWhenNoTracking(INavigationBase, Object)

Calls SetLoaded(Object, String, Boolean) for a INavigationBase to mark it as loaded when a no-tracking query has eagerly loaded this relationship.
GetCurrentValueComparer(IPropertyBase)

Gets a IComparer<T> for comparing values in tracked IUpdateEntry entries.

GetFieldName(IPropertyBase)

Gets the name of the backing field for this property, or null if the backing field is not known.
GetGetter(IPropertyBase)

Gets a IClrPropertyGetter for reading the value of this property.

Note that it is an error to call this method for a shadow property (IsShadowProperty(IPropertyBase)) since such a property has no associated MemberInfo.

GetIndex(IPropertyBase)

Gets the property index for this property.
GetMemberInfo(IPropertyBase, Boolean, Boolean)

Gets the PropertyInfo or FieldInfo that should be used to get or set a value for the given property.

Note that it is an error to call this method for a shadow property (IsShadowProperty(IPropertyBase)) since such a property has no associated MemberInfo.

GetPropertyAccessMode(IPropertyBase)

Gets the PropertyAccessMode being used for this property. null indicates that the default property access mode is being used.

IsIndexerProperty(IPropertyBase)

Gets a value indicating whether this is an indexer property. An indexer property is one that is accessed through an indexer on the entity class.
IsShadowProperty(IPropertyBase)
Obsolete.

Gets a value indicating whether this is a shadow property. A shadow property is one that does not have a corresponding property in the entity class. The current value for the property is stored in the ChangeTracker rather than being stored in instances of the entity class.
