Overloads

SetField(FieldInfo, Boolean)
Obsolete.

Sets the FieldInfo for the underlying CLR field that this property should use.

By default, the backing field, if one is found or has been specified, is used when new objects are constructed, typically when entities are queried from the database. Properties are used for all other accesses. This can be changed by calling SetPropertyAccessMode(Nullable<PropertyAccessMode>, Boolean).

SetField(String, Boolean)

Sets the underlying CLR field that this property should use. This may be null for shadow properties or if the backing field for the property is not known.

Public Overridable Function SetField (fieldName As String, Optional fromDataAnnotation As Boolean = false) As FieldInfo
Public Function SetField (fieldName As String, Optional fromDataAnnotation As Boolean = false) As FieldInfo

Parameters

fieldName
String

The name of the field to use.

fromDataAnnotation
Boolean

Indicates whether the configuration was specified using a data annotation.

Returns

FieldInfo

The new FieldInfo.

Remarks

Backing fields are normally found by convention. This method is useful for setting backing fields explicitly in cases where the correct field is not found by convention.

By default, the backing field, if one is found or has been specified, is used when new objects are constructed, typically when entities are queried from the database. Properties are used for all other accesses. This can be changed by calling SetPropertyAccessMode(Nullable<PropertyAccessMode>, Boolean).

See Backing fields for more information and examples.
