Remarks

Instances of this class are returned from methods when using the ModelBuilder API and it is not designed to be directly constructed in your application code.

See Modeling entity types and relationships for more information and examples.

Constructors

ElementTypeBuilder(IMutableElementType)

This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.

Properties

Metadata

The element type being configured.

Methods

HasAnnotation(String, Object)	Adds or updates an annotation on the element type. If an annotation with the key specified in `annotation` already exists its value will be updated.
HasConversion(Type)	Configures elements of the collection so that their values are converted before writing to the database and converted back when reading from the database.
HasConversion(Type, Type)	Configures elements of the collection so that their values are converted before writing to the database and converted back when reading from the database.
HasConversion(Type, ValueComparer)	Configures elements of the collection so that their values are converted before writing to the database and converted back when reading from the database.
HasConversion(ValueConverter)	Configures elements of the collection so that their values are converted to and from the database using the given ValueConverter.
HasConversion(ValueConverter, ValueComparer)	Configures elements of the collection so that their values are converted before using the given ValueConverter.
HasConversion<TConversion,TComparer>()	Configures elements of the collection so that their values are converted before writing to the database and converted back when reading from the database.
HasConversion<TConversion>()	Configures elements of the collection so their values are converted before writing to the database and converted back when reading from the database.
HasConversion<TConversion>(ValueComparer)	Configures elements of the collection so that their values are converted before writing to the database and converted back when reading from the database.
HasMaxLength(Int32)	Configures the maximum length of data that can be stored in elements of the collection.
HasPrecision(Int32)	Configures the precision of elements of the collection.
HasPrecision(Int32, Int32)	Configures the precision and scale of elements of the collection.
IsRequired(Boolean)	Configures whether elements of the collection must have a value or can be `null`. An element can only be configured as non-required if it is based on a CLR type that can be assigned `null`.
IsUnicode(Boolean)	Configures whether elements of the collection are capable of persisting unicode characters.
