Class EntityProjectionExpression

Namespace

Microsoft.EntityFrameworkCore.Query

Assembly

Microsoft.EntityFrameworkCore.Relational.dll

An expression that represents an entity in the projection of SelectExpression.

This type is typically used by database providers (and other extensions). It is generally not used in application code.

Methods

AddNavigationBinding(INavigation, EntityShaperExpression)

Adds a navigation binding for this entity projection when the target entity type of the navigation is owned or weak.

public virtual void AddNavigationBinding(INavigation navigation, EntityShaperExpression entityShaper)

Parameters

navigation INavigation

A navigation to add binding for.

entityShaper EntityShaperExpression

An entity shaper expression for the target type.

BindNavigation(INavigation)

Binds a navigation with this entity projection to get entity shaper for the target entity type of the navigation which was previously added using AddNavigationBinding(INavigation, EntityShaperExpression) method.

public virtual EntityShaperExpression? BindNavigation(INavigation navigation)

Parameters

navigation INavigation

A navigation to bind.

Returns

EntityShaperExpression

An entity shaper expression for the target entity type of the navigation.

public virtual ColumnExpression BindProperty(IProperty property)

Parameters

property IProperty

A property to bind.

Returns

ColumnExpression

A column which is a SQL representation of the property.

MakeNullable()
