PrimitivePropertyConfiguration.HasColumnAnnotation(String, Object) Method

Definition

Sets an annotation in the model for the database column used to store the property. The annotation value can later be used when processing the column such as when creating migrations.

public System.Data.Entity.ModelConfiguration.Configuration.PrimitivePropertyConfiguration HasColumnAnnotation (string name, object value);
member this.HasColumnAnnotation : string * obj -> System.Data.Entity.ModelConfiguration.Configuration.PrimitivePropertyConfiguration
Public Function HasColumnAnnotation (name As String, value As Object) As PrimitivePropertyConfiguration

Parameters

name
String

The annotation name, which must be a valid C#/EDM identifier.

value
Object

The annotation value, which may be a string or some other type that can be serialized with an IMetadataAnnotationSerializer

Returns

PrimitivePropertyConfiguration

The same PrimitivePropertyConfiguration instance so that multiple calls can be chained.

Remarks

It will likely be necessary to register a IMetadataAnnotationSerializer if the type of the annotation value is anything other than a string. Passing a null value clears any annotation with the given name on the column that had been previously set.
